[Modes for carrying out the invention]

[0010] <First Embodiment> The karaoke device K according to the first embodiment will be described with reference to Figures 1 to 5B.

[0011] ==Karaoke Equipment== The karaoke device K is a device for karaoke performance of music and for users to perform karaoke singing. Further, the karaoke device K according to the present embodiment can implement content (hereinafter sometimes referred to as "karaoke bingo") that combines karaoke singing and a bingo game by executing a dedicated program (details will be described later).

[0012] As shown in FIG. 1, the karaoke device K includes a karaoke main body 10, a speaker 20, a display device 30, a microphone 40, and a remote control device 50. The karaoke main body 10 performs various controls related to karaoke performance and karaoke singing, such as karaoke performance control of the selected music, display control of lyrics, background images, etc., and processing of the audio signal input through the microphone 40. The speaker 20 is a configuration for emitting sound based on the sound emission signal from the karaoke main body 10. The display device 30 is a configuration for displaying images and pictures on the screen based on the signal from the karaoke main body 10. The microphone 40 is a configuration for converting the singing voice of the user's karaoke singing into an analog audio signal and inputting it to the karaoke main body 10. The remote control device 50 is a device for performing various operations on the karaoke main body 10.

[0013] As shown in FIG. 2, the karaoke main body 10 according to the present embodiment includes a storage means 10a, a communication means 10b, an input means 10c, a performance means 10d, and a control means 10e. Each component is connected to the bus B via an interface (not shown).

[0014] [Storage means] The storage means 10a is a large-capacity storage device that stores various data, such as a hard disk drive or the like. The storage means 10a stores a plurality of music pieces (specifically, music data corresponding to each music piece).

[0015] The song data includes song identification information to identify each individual song. This song identification information is unique to each song, such as a song ID used to identify the song. The song data also includes accompaniment data, reference data, and section information. The accompaniment data is the data that forms the basis of the karaoke performance sound. The reference data is data that shows the singing melody of the song that has been performed in karaoke, and is used when scoring the user's karaoke performance. The section information indicates the performance section. The performance section is the section in which the karaoke performance takes place. The performance section includes singing sections and non-singing sections. The singing section is the section in the song where lyrics to be sung are set (for example, the A section, B section, and chorus of the first verse). The non-singing section is the section in the song where lyrics to be sung are not set, such as the intro, interlude, and outro.

[0016] The storage means 10a stores lyric data for displaying the lyrics corresponding to each song on the display device 30 in sync with the karaoke performance, background video data such as background images displayed on the display device 30 during karaoke performance, and song attribute information (song title, artist name, genre, performance time, etc.).

[0017] [Communication methods / Input methods] The communication means 10b provides an interface for communicating with the remote control device 50. The input means 10c is configured for the user to input various instructions. The input means 10c is a button or the like provided on the karaoke unit 10. Alternatively, the remote control device 50 may function as the input means 10c.

[0018] [Means of performance] The performance means 10d performs karaoke performance of a song and processes signals based on singing voice input through the microphone 40, based on the control of the control means 10e. The performance means 10d includes a sound source, mixer, amplifier, etc. (none of which are shown in the figure).

[0019] [Control means] The control means 10e performs various controls on the karaoke machine K. The control means 10e includes a CPU and memory (neither of which are shown in the figure). The CPU implements various functions by executing programs stored in the memory.

[0020] In this embodiment, the CPU executes a dedicated karaoke bingo program stored in memory, and the control means 10e functions as a first extraction unit 101, a second extraction unit 102, a selection unit 103, a card display control unit 104, a reservation processing unit 105, a performance control unit 106, and a game control unit 107.

[0021] (First extraction unit) The first extraction unit 101 extracts a predetermined number of songs from among the multiple songs stored in the storage means 10a.

[0022] The first predetermined number is not particularly limited as long as it is less than or equal to the maximum number of songs that can be played on the karaoke machine K (i.e., songs whose song data is stored in the storage means 10a). The first predetermined number may be set to a single value in advance, such as "100 songs" or "500 songs," or it may be set to multiple values ​​depending on the difficulty level of the karaoke bingo. In the latter case, the first extraction unit 101 sets the first predetermined number according to the difficulty level of the karaoke bingo selected by the user via the remote control device 50 or the like. For example, the first extraction unit 101 sets the first predetermined number to "100 songs" when the difficulty level is "low," sets the first predetermined number to "300 songs" when the difficulty level is "medium," and sets the first predetermined number to "500 songs" when the difficulty level is "high."

[0023] Music can be extracted in various ways. For example, the first extraction unit 101 can randomly select 500 songs from the 200,000 songs stored in the storage means 10a.

[0024] (Second extraction section) The second extraction unit 102 extracts each word from the lyrics of the extracted song.

[0025] The second extraction unit 102 reads the lyrics data of a song extracted by the first extraction unit 101 from the storage means 10a and uses known techniques (for example, text mining) to extract words contained in the lyrics indicated by the lyrics data.

[0026] The second extraction unit 102 extracts multiple words by performing the same process on all the songs extracted by the first extraction unit 101.

[0027] The second extraction unit 102 can extract each word from the lyrics of the extracted song by comparing the extracted words and removing duplicate words.

[0028] Alternatively, the second extraction unit 102 creates a word table in advance in a portion of the storage area of ​​the storage means 10a. The word table is a table consisting of "words," "number of songs," and "duplicate flag." "Words" are specific words extracted from the lyrics indicated by the lyrics data. "Number of songs" is the number of songs that contain a certain word. For example, if 500 songs are extracted, the maximum value of "number of songs" will be "500." The "duplicate flag" is a flag that is set if the same word appears two or more times in a single song.

[0029] The second extraction unit 102 reads the lyrics data of a song extracted by the first extraction unit 101 from the storage means 10a, and extracts the words contained in the lyrics indicated by the lyrics data in order using known techniques, similar to the above.

[0030] The second extraction unit 102 checks whether a certain extracted word is registered in the word table. If the word is registered and the "duplicate flag" is "0", the second extraction unit 102 increments the "number of songs" and sets the "duplicate flag" to "1". Also, if the word is registered and the "duplicate flag" is "1", the second extraction unit 102 determines that the word has already been extracted in one song and does not perform any special processing.

[0031] On the other hand, if a certain word is not registered, the second extraction unit 102 registers that word in the word table and sets the "number of songs" and "duplicate flag" to "1".

[0032] After performing the same process for all words in one song, the second extraction unit 102 sets all "duplicate flags" in the word table to "0" and then extracts words that are included in the lyrics indicated by the lyrics data of other songs.

[0033] The second extraction unit 102 performs the same processing on all the songs extracted by the first extraction unit 101, thereby extracting each word from the lyrics of the extracted songs. In addition, the number of songs containing each word can also be determined.

[0034] (Selection section) The selection unit 103 selects a second predetermined number of words from the extracted multiple words.

[0035] The second predetermined number is the number of words used in karaoke bingo. This second predetermined number is set in advance. For example, a typical bingo game uses a card with numbers from 1 to 75 randomly placed in a 5x5 grid. When using a card of the same format (bingo game card) in karaoke bingo, the second predetermined number is "75".

[0036] Word selection can be performed in various ways. For example, the selection unit 103 can randomly select a second predetermined number of words from among the multiple words extracted by the second extraction unit 102.

[0037] (Card display control unit) The card display control unit 104 generates a bingo game card in which a third predetermined number of words or identifiers corresponding to selected words are placed in the squares, and displays it on the display means.

[0038] The identifiers corresponding to the words are used to distinguish each word, such as numbers or combinations of letters and numbers. In other words, the identifiers are different for each word. The third predetermined number is the number of words or identifiers to be placed on a single bingo game card. As mentioned above, a 5x5 grid card is used in a typical bingo game. In this case, the third predetermined number is "25". The third predetermined number is set in advance. Note that some cards used in typical bingo games have "FREE" in the center. In this case, the third predetermined number is "24". The display means are the display device 30 and the remote control device 50.

[0039] For example, suppose the word "75" is selected in the selection unit 103. Also, suppose the third predetermined number is "24". In this case, the card display control unit 104 randomly selects "24" words from the "75" words and generates a bingo game card by arranging the selected words in a 5x5 grid. The card display control unit 104 displays the generated bingo game card on the display device 30.

[0040] Alternatively, the card display control unit 104 assigns different identifiers to the selected "75" words. The card display control unit 104 stores a table showing the relationship between words and identifiers in the storage means 10a. The card display control unit 104 randomly selects "24" identifiers from the assigned identifiers and generates a bingo game card by arranging the selected identifiers in a 5x5 grid. The card display control unit 104 displays the generated bingo game card on the display device 30.

[0041] (Reservation processing) The reservation processing unit 105 reserves the song selected by the user.

[0042] Users who wish to sing karaoke select songs via the remote control device 50 or the like. The reservation processing unit 105 reserves a song (i.e., reserves a karaoke performance) by registering the song identification information of the song selected by the user in the reservation queue.

[0043] (Performance Control Unit) The performance control unit 106 controls the performance means 10d to perform karaoke performance of the reserved song.

[0044] The performance control unit 106 acquires song accompaniment data from the storage means 10a based on song identification information registered in the reservation queue. The performance control unit 106 plays the acquired accompaniment data and controls the performance means 10d to emit karaoke performance sound from the speaker 20.

[0045] Users can sing karaoke using the microphone 40 in time with the karaoke music emitted from speaker 20.

[0046] (Game Control Unit) The game control unit 107 changes the display mode of the word or the identifier corresponding to the word, and / or the display mode of the square on which the word or the identifier corresponding to the word is located, if the word or the identifier corresponding to the word is present in the bingo game card when the user sings karaoke in conjunction with the karaoke performance of a reserved song.

[0047] The display can be changed in various ways. For example, if a word entered by voice during a user's karaoke performance is present on the bingo card, the game control unit 107 can make the display of that word (e.g., color, font size) different from that of other words. Alternatively, the game control unit 107 can make the display of the square on the bingo card where that word is placed (e.g., color) different from that of other squares. Furthermore, if an identifier corresponding to a word entered by voice during a user's karaoke performance is present on the bingo card, the game control unit 107 can display the word in place of that identifier.

[0048] Assuming that a bingo game card with words placed on it is displayed on the display device 30, and the user selects a song and sings karaoke, the game control unit 107 uses known technology to analyze the user's singing voice input via the microphone 40 and detects words contained in the singing voice. The game control unit 107 checks whether the detected words are present on the displayed bingo game card. If the detected words are present on the bingo game card, the game control unit 107 changes the display mode of the word and / or the display mode of the square on which the word is placed.

[0049] Furthermore, suppose that a bingo game card with identifiers placed on it is displayed on the display device 30, and the user selects a song and sings karaoke. In this case, the game control unit 107 performs the same processing as above to detect words contained in the singing voice. The game control unit 107 refers to a table showing the relationship between words and identifiers stored in the storage means 10a and identifies the identifier corresponding to the detected word. The game control unit 107 checks whether the identified identifier is present on the displayed bingo game card. If the identified identifier is present on the bingo game card, the game control unit 107 changes the display mode of the identifier and / or the display mode of the square on which the identifier is placed.

[0050] The game control unit 107 repeats the above process until a bingo is achieved (when the display pattern of all words in a row or the identifier corresponding to those words changes). If a bingo is not achieved with one song, the game control unit 107 controls the performance means 10d to play the karaoke version of the next song reserved after the first song.

[0051] Furthermore, the game control unit 107 can temporarily hide the display of the bingo game card during karaoke singing in order to make the lyrics and background video easier to see. Alternatively, the game control unit 107 may display the bingo game card in a reduced size, or it may display it only on the display screen of the remote control device 50. In addition, the game control unit 107 can display the word "Reach" when the player is one word away from bingo or the identifier corresponding to that word, or display the word "Bingo!" when the player has achieved bingo.

[0052] Furthermore, the game control unit 107 can control the performance means 10d to stop the currently running karaoke performance if it changes the display mode of a word or an identifier corresponding to that word, and / or the display mode of the square where the word or an identifier corresponding to that word is located. The game control unit 107 can also control the performance means 10d to stop the currently running karaoke performance if a bingo is achieved.

[0053] ==Regarding the operation of the karaoke machine== Next, a specific example of the operation of the karaoke device K in this embodiment will be described with reference to Figures 3 to 5B. Figure 3 is a flowchart showing an example of the operation of the karaoke device K. Figure 4 is a table showing the relationship between words and identifiers. Figures 5A and 5B are bingo game cards displayed on the display device 30. Here, an example using a bingo game card in which identifiers corresponding to words are placed in the squares will be described.

[0054] User U operates the remote control device 50 to select karaoke bingo content. The karaoke device K starts karaoke bingo. The CPU of the control means 10e functions as a first extraction unit 101, a second extraction unit 102, a selection unit 103, a card display control unit 104, a reservation processing unit 105, a performance control unit 106, and a game control unit 107 by executing a dedicated karaoke bingo program stored in memory.

[0055] The first extraction unit 101 extracts a predetermined number of songs from among the multiple songs stored in the storage means 10a (extracting a predetermined number of songs; step 10). For example, the first extraction unit 101 extracts 500 songs (song X1 to song X500) from among the multiple songs stored in the storage means 10a.

[0056] The second extraction unit 102 extracts each word from the lyrics of the songs extracted in step 10 (extracting each word from the lyrics; step 11). The second extraction unit 102 performs the above process on each of the songs X1 to X500 extracted by the first extraction unit 101, thereby extracting each word from the lyrics of the extracted songs X1 to X500.

[0057] The selection unit 103 selects a second predetermined number of words from the multiple words extracted in step 11 (selection of a second predetermined number of words; step 12). For example, the selection unit 103 selects the word "75" from the multiple words extracted.

[0058] The card display control unit 104 generates a bingo game card in which identifiers corresponding to a third predetermined number of words are placed in the squares from the identifiers corresponding to the words selected in step 12, and displays it on the display device 30 (display the bingo game card; step 13).

[0059] Specifically, the card display control unit 104 assigns different identifiers "1 to 75" to the selected word "75". The card display control unit 104 stores a table showing the relationship between words and identifiers in the storage means 10a (see Figure 4).

[0060] The card display control unit 104 randomly selects "24" identifiers from the assigned identifiers and generates a bingo game card by arranging the selected identifiers in a 5x5 grid. The card display control unit 104 then displays the generated bingo game card on the display device 30 (see Figure 5A). In the bingo game card shown in Figure 5A, the central part is a "FREE" square.

[0061] The reservation processing unit 105 reserves the song selected by the user (reserves the song; step 14). Users playing karaoke bingo predict songs that contain words corresponding to the identifier on the displayed bingo game card and select a song via the remote control device 50. The reservation processing unit 105 reserves song X1 by registering the song ID of song X1 selected by the user in the reservation queue.

[0062] The performance control unit 106 controls the performance means 10d to perform karaoke performance of the song reserved in step 14 (karaoke performance of the reserved song; step 15). For example, the performance control unit 106 obtains the accompaniment data for song X1 from the storage means 10a based on the song ID registered in the reservation queue. The performance control unit 106 plays the obtained accompaniment data and controls the performance means 10d to emit karaoke performance sound from the speaker 20. The user U sings karaoke of song X1 using the microphone 40 in time with the karaoke performance sound emitted from the speaker 20.

[0063] The game control unit 107 checks whether an identifier corresponding to a word voice-input during the user's karaoke singing accompanying the karaoke performance of a reserved song exists on the bingo game card displayed in step 13.

[0064] If an identifier corresponding to a word voice-input during the karaoke performance of a reserved song is present on the bingo game card displayed in step 13 (if the result is Y in step 16), the game control unit 107 changes the display mode of the identifier corresponding to the word (change the display mode of the identifier; step 17).

[0065] Specifically, suppose user U selects song X1 and performs karaoke. In this case, the game control unit 107 uses known technology to analyze user U's singing voice input via microphone 40 and detects the word "dark night" contained in the singing voice. The game control unit 107 refers to a table (Figure 4) showing the relationship between words and identifiers stored in the memory means 10a and identifies identifier "3" corresponding to the detected word "dark night". The game control unit 107 checks whether the identified identifier "3" is present on the displayed bingo game card. The bingo game card in Figure 5A has identifier "3". Therefore, the game control unit 107 changes the display of identifier "3" and displays the word "dark night" instead of identifier "3" (see Figure 5B).

[0066] The karaoke device K repeatedly performs the processes from step 14 to step 17 until the display pattern of all the identifiers in a row of the bingo game card changes and a bingo is achieved (until it becomes Y in step 18).

[0067] As is clear from the above, the karaoke device K according to this embodiment includes: a first extraction unit 101 that extracts a first predetermined number of songs from a plurality of songs stored in the storage means 10a; a second extraction unit 102 that extracts words included in the lyrics of the extracted songs word by word; a selection unit 103 that selects a second predetermined number of words from the plurality of extracted words; a card display control unit 104 that generates a bingo game card in which a third predetermined number of words or identifiers corresponding to those words are placed in squares from the selected words or identifiers corresponding to those words, and displays it on the display means; a reservation processing unit 105 that reserves songs selected by the user; a performance control unit 106 that controls the performance means 10d to perform karaoke of the reserved songs; and a game control unit 107 that, when a word or identifier corresponding to that word is voice-input during the user's karaoke singing accompanying the karaoke performance of the reserved song, changes the display mode of the word or identifier corresponding to that word, and / or the display mode of the squares in which the word or identifier corresponding to that word is placed, in the bingo game card.

[0068] With this karaoke device K, a bingo game card is generated in which words included in the lyrics of a song or identifiers corresponding to those words are placed in squares, and the display of the bingo game card can be changed in accordance with the singing of karaoke. Therefore, users can enjoy a bingo game by singing karaoke. In other words, with the karaoke device K according to this embodiment, a new content combining karaoke singing and a bingo game can be implemented.

[0069] <Modified form of the first embodiment> The above example described a scenario where one user plays the karaoke bingo game on a single karaoke machine. However, it is also possible for multiple users to play the karaoke bingo game on a single karaoke machine.

[0070] In this case, for example, as in the embodiment described above, a bingo game card can be created, and multiple users can take turns singing karaoke to play bingo.

[0071] On the other hand, when the karaoke machine K implements content that combines karaoke singing and a bingo game with multiple users, the card display control unit 104 can generate multiple bingo game cards according to the number of users and display them on the display means. At least one of the words or identifiers corresponding to words placed in the squares of one bingo game card is different from the words or identifiers corresponding to words placed in the squares of another bingo game card.

[0072] For example, when four users play karaoke bingo, one user operates the remote control device 50 and inputs the number of users, "4 people". The card display control unit 104 generates four types of bingo game cards according to the input number of users, "4 people".

[0073] The card display control unit 104 displays the four generated bingo game cards on the display device 30. Figure 6 shows the four bingo game cards displayed on the display device 30. The space above the bingo game cards can be used to display song lyrics or background images.

[0074] The position where the bingo game cards are displayed is not limited to the example in Figure 6, and can be adjusted as appropriate depending on the number and size of the bingo game cards. Furthermore, when the game control unit 107 changes the display mode of a word or the identifier corresponding to that word, and / or the display mode of the square on which the word or the identifier corresponding to that word is placed, it can temporarily display the bingo game card on which the word or the identifier corresponding to that word is placed larger than the other bingo game cards. Alternatively, the game control unit 107 may change the display size of the bingo game cards according to the number of times the display mode has changed. For example, the game control unit 107 can display bingo game cards that have had their display mode changed more often larger.

[0075] As is clear from the above, when multiple users perform content that combines karaoke singing and a bingo game in the karaoke device K according to this modified example, the card display control unit 104 generates multiple bingo game cards according to the number of users and displays them on the display means. With such a karaoke device K, multiple users can perform karaoke bingo content.

[0076] <Second Embodiment> Next, with reference to Figures 7 to 10B, the karaoke device K according to the second embodiment will be described. In this embodiment, an example of playing karaoke bingo will be described in which bingo game cards generated by the karaoke device are displayed on a mobile terminal. Detailed explanations of the same configuration as in the first embodiment will be omitted.

[0077] ==Karaoke System== A karaoke system includes karaoke equipment and portable terminals.

[0078] A mobile terminal is a smartphone or tablet owned by the user, or a dedicated computer pre-installed in a karaoke room equipped with a karaoke machine. In this embodiment, the remote control device of the karaoke machine can also be used as a mobile terminal. Each mobile terminal is assigned terminal identification information. Terminal identification information is unique to each mobile terminal, such as a terminal ID used to identify the mobile terminal. Each mobile terminal has means of display, such as a display, which are commonly found in smartphones and the like.

[0079] The mobile terminal in this embodiment has dedicated application software (hereinafter referred to as "content app") installed for using content that combines karaoke singing and a bingo game (karaoke bingo). The content app can be obtained by downloading it from a designated website.

[0080] The karaoke machine is connected to a mobile device via a network such as a public telephone network or short-range wireless communication such as Wi-Fi (registered trademark). By launching a content application on the mobile device, the mobile device and the karaoke machine are connected in a communicative manner.

[0081] As shown in Figure 7, the karaoke system 1 according to this embodiment includes a mobile terminal M and a karaoke device K. The mobile terminal M is operated by a user U. A content application is installed on the mobile terminal M.

[0082] ==Karaoke Equipment== [g means] The communication means 10b according to this embodiment provides an interface for communicating with the remote control device 50 and the mobile terminal M.

[0083] [Control means] In this embodiment, the CPU executes a dedicated karaoke bingo program stored in memory, and the control means 10e functions as a first extraction unit 101, a second extraction unit 102, a selection unit 103, a reservation processing unit 105, a performance control unit 106, and a card distribution unit 108 (see Figure 8).

[0084] (Card Distribution Department) The card distribution unit 108 generates a bingo game card in which a third predetermined number of words or identifiers corresponding to selected words are placed in the squares, and distributes the card data corresponding to the bingo game card to the mobile terminal.

[0085] The generation of bingo game cards can be carried out in the same manner as in the first embodiment. The card distribution unit 108 distributes the card data corresponding to the generated bingo game cards to a mobile terminal that is capable of communication (i.e., a mobile terminal running the content application). The mobile terminal displays the bingo game cards on its display based on the received card data.

[0086] Furthermore, in this embodiment, if a word or an identifier corresponding to such word is voice-input by the user during karaoke singing accompanying the karaoke performance of a reserved song, the card distribution unit 108 generates a new bingo game card with updated display patterns for the word or the identifier corresponding to such word, and / or the display patterns for the squares where the word or the identifier corresponding to such word is located, and distributes the card data corresponding to the new bingo game card to the mobile terminal.

[0087] The display mode can be updated in various ways, similar to the change in the display mode in the first embodiment. For example, if a word that has been voice-input by the user during karaoke singing is present on the bingo game card, the card distribution unit 108 generates a new bingo game card with an updated display mode by making the display of that word (for example, color, font size) different from other words.

[0088] When a new bingo game card is generated, the card distribution unit 108 distributes the card data corresponding to the new bingo game card to the mobile terminal. The mobile terminal then displays the new bingo game card based on the received card data on its screen, replacing the previously displayed bingo game card.

[0089] The card distribution unit 108 repeats the above process until it distributes card data that has become a bingo (when the display pattern of all words in a row or the identifier corresponding to those words has changed).

[0090] Furthermore, if the card distribution unit 108 is one word away from a bingo or an identifier corresponding to that word, it can also transmit the word "Reach" along with the card data corresponding to the new bingo game card. The mobile terminal displays the word "Reach" based on the received text data along with the new bingo game card based on the received card data on its display. Alternatively, if a bingo is achieved, the mobile terminal can also transmit the word "Bingo" along with the card data corresponding to the new bingo game card. The mobile terminal displays the word "Bingo" based on the received text data along with the new bingo game card based on the received card data on its display.

[0091] ==Regarding the operation of the karaoke machine== Next, a specific example of the operation of the karaoke device K in this embodiment will be described with reference to Figures 9 to 10B. Figure 9 is a flowchart showing an example of the operation of the karaoke device K. Figures 10A and 10B are bingo game cards displayed on the display device. Here, we will describe an example using bingo game cards in which words are arranged in squares. In addition, user U is running a content application on their own mobile terminal M. The karaoke device K and the mobile terminal M are connected in a way that allows them to communicate with each other.

[0092] User U operates the remote control device 50 to select karaoke bingo content. The karaoke device K starts karaoke bingo. The CPU of the control means 10e functions as a first extraction unit 101, a second extraction unit 102, a selection unit 103, a reservation processing unit 105, a performance control unit 106, and a card distribution unit 108 by executing a dedicated karaoke bingo program stored in memory.

[0093] The first extraction unit 101 extracts a predetermined number of songs from among the multiple songs stored in the storage means 10a (extracting a predetermined number of songs; step 20). For example, the first extraction unit 101 extracts 500 songs (song X1 to song X500) from among the multiple songs stored in the storage means 10a.

[0094] The second extraction unit 102 extracts each word from the lyrics of the songs extracted in step 20 (extracting each word from the lyrics; step 21). The second extraction unit 102 performs the same processing as in the first embodiment for each of the songs X1 to X500 extracted by the first extraction unit 101, thereby extracting each word from the lyrics of the extracted songs X1 to X500.

[0095] The selection unit 103 selects a second predetermined number of words from the multiple words extracted in step 12 (selection of a second predetermined number of words; step 22). For example, the selection unit 103 selects the word "75" from the multiple words extracted.

[0096] The card distribution unit 108 generates a bingo game card by placing a third predetermined number of words from the words selected in step 22 into the squares, and distributes the card data corresponding to the bingo game card to the mobile terminal M (distribution of the bingo game card to the mobile terminal; step 23).

[0097] Specifically, the card distribution unit 108 randomly selects 24 words from the selected 75 words and generates a bingo game card by arranging the selected words in a 5x5 grid. The card distribution unit 108 then distributes the card data corresponding to the generated bingo game card to the mobile terminal M. The mobile terminal M displays the bingo game card based on the received card data on its screen (see Figure 10A). In the bingo game card shown in Figure 10A, the central part is a "FREE" square.

[0098] The reservation processing unit 105 reserves the song selected by the user (reserves the song; step 24). Users playing karaoke bingo predict which songs contain the words on the bingo game card displayed on the mobile terminal M's screen and select the song via the remote control device 50. The reservation processing unit 105 reserves song X1 by registering the song ID of song X1 selected by the user in the reservation queue.

[0099] The performance control unit 106 controls the performance means 10d to perform karaoke performance of the song reserved in step 24 (karaoke performance of the reserved song; step 25). For example, the performance control unit 106 obtains the accompaniment data for song X1 from the storage means 10a based on the song ID registered in the reservation queue. The performance control unit 106 plays the obtained accompaniment data and controls the performance means 10d to emit karaoke performance sound from the speaker 20. The user U sings karaoke of song X1 using the microphone 40 in time with the karaoke performance sound emitted from the speaker 20.

[0100] The card distribution unit 108 checks whether the words voice-input by the user during karaoke singing accompanying the karaoke performance of the reserved song are present in the bingo game card distributed in step 23.

[0101] If a word entered by the user during karaoke singing accompanying the karaoke performance of a reserved song is present in the bingo game card distributed in step 23 (if Y in step 26), the card distribution unit 108 generates a new bingo game card with updated word display formatting and distributes card data corresponding to the new bingo game card to the mobile terminal M (distributes card data corresponding to the new bingo game card to the mobile terminal; step 27).

[0102] Specifically, suppose user U selects song X1 and performs karaoke. In this case, the card distribution unit 108 uses known technology to analyze user U's singing voice input via microphone 40 and detects the word "machine" contained in the singing voice. The card distribution unit 108 checks whether the word "machine" is present in the distributed bingo game card. The bingo game card in Figure 10A contains the word "machine". In this case, the card distribution unit 108 generates a new bingo game card with updated display patterns for the squares where the word "machine" is placed. The card distribution unit 108 distributes card data corresponding to the newly generated bingo game card to the mobile terminal M. The mobile terminal M displays the new bingo game card based on the received card data on its display (see Figure 10B).

[0103] The karaoke device K updates the display of the squares where all the words in a row of the bingo game card are placed, and repeats the process from step 24 to step 27 until a bingo is achieved (until it becomes Y in step 28).

[0104] As is clear from the above, the karaoke device K according to this embodiment is communicably connected to a mobile terminal M. The karaoke device K includes a first extraction unit 101 that extracts a first predetermined number of songs from a plurality of songs stored in the storage means 10a, a second extraction unit 102 that extracts words contained in the lyrics of the extracted songs word by word, a selection unit 103 that selects a second predetermined number of words from the plurality of extracted words, a card distribution unit 108 that generates a bingo game card in which a third predetermined number of words or identifiers corresponding to those words are placed in squares from the selected words or identifiers corresponding to those words, and distributes card data corresponding to the bingo game card to the mobile terminal, a reservation processing unit 105 that reserves songs selected by the user, and a performance control unit 106 that controls the performance means 10d to perform karaoke performance of the reserved songs. The card distribution unit 108, when it detects a word or an identifier corresponding to a word that has been voice-input during the user's karaoke performance accompanying the karaoke playback of a reserved song, generates a new bingo game card with updated display patterns for the word or the identifier and / or the squares on which the word or the identifier is located, and distributes the card data corresponding to the new bingo game card to the mobile terminal M.

[0105] With this karaoke device K, it is possible to generate a bingo game card in which words contained in the lyrics of a song or identifiers corresponding to those words are placed in squares, and to deliver it to the user's mobile terminal. Furthermore, the karaoke device K can generate a new bingo game card with an updated display in accordance with the karaoke singing, and deliver card data corresponding to the new bingo game card to the mobile terminal M. Therefore, the user can check the bingo game card on their mobile terminal. In other words, with the karaoke device K according to this embodiment, it is possible to implement new content that combines karaoke singing and bingo games.

[0106] <Modified form of the second embodiment> The above example described a scenario where one user plays the karaoke bingo game on a single karaoke machine. However, it is also possible for multiple users to play the karaoke bingo game on a single karaoke machine.

[0107] In this case, for example, a bingo game card can be created and distributed to a mobile device, as in the embodiment described above. Multiple users can then play the bingo game by taking turns singing karaoke.

[0108] On the other hand, when the karaoke machine K implements content that combines karaoke singing and a bingo game with multiple users, the card distribution unit 108 can generate multiple bingo game cards according to the number of users and distribute the card data corresponding to the bingo game cards to each user's mobile terminal.

[0109] For example, when four users play karaoke bingo, one user operates the remote control device 50 and inputs the number of users, "4". The card distribution unit 108 generates four types of bingo game cards according to the input number of users, "4". It is assumed that each user is running the content application on their mobile device. When the mobile device starts the content application, it sends its own device ID to the karaoke device K.

[0110] The card distribution unit 108 associates one terminal ID with each of the four types of bingo game cards it has generated. The card distribution unit 108 then distributes the card data corresponding to the bingo game cards to the mobile terminals according to the terminal IDs associated with the bingo game cards.

[0111] The card distribution unit 108 generates new bingo game cards that update the display of the word or the identifier, and / or the display of the square where the word or the identifier is located, for only the bingo game cards that contain a word or an identifier that was voice-input during the user's karaoke singing accompanying the karaoke performance of the reserved song, and distributes the card data corresponding to the new bingo game cards to the mobile terminal.

[0112] For example, if a user sings karaoke, the card distribution unit 108 uses known technology to analyze the user's singing voice input via the microphone 40 and detects words contained in the singing voice. The card distribution unit 108 then checks whether the detected words are present in each of the four types of bingo game cards corresponding to the distributed card data. Here, the card distribution unit 108 determines that the detected words are present in two of the four types of bingo game cards, C1 and C2, that correspond to the distributed card data.

[0113] In this case, the card distribution unit 108 generates a new bingo game card C1' to replace the bingo game card C1. The card distribution unit 108 also generates a new bingo game card C2' to replace the bingo game card C2. The card distribution unit 108 refers to the terminal ID associated with bingo game card C1 and distributes the card data corresponding to the new bingo game card C1' to the mobile terminal that distributed the card data corresponding to bingo game card C1. The mobile terminal displays the new bingo game card C1' based on the received card data on its display. The card distribution unit 108 also refers to the terminal ID associated with bingo game card C2 and distributes the card data corresponding to the new bingo game card C2' to the mobile terminal that distributed the card data corresponding to bingo game card C2. The mobile terminal displays the new bingo game card C2' based on the received card data on its display.

[0114] As is clear from the above, when multiple users perform content combining karaoke singing and a bingo game in the karaoke device K according to this modified example, the card distribution unit 108 generates multiple bingo game cards according to the number of users and distributes the card data corresponding to the bingo game cards to each user's mobile terminal. Furthermore, the card distribution unit 108 generates new bingo game cards with updated display patterns only for bingo game cards that contain words or identifiers corresponding to words that were voice-input during the karaoke performance of the reserved song, and distributes the card data corresponding to these new bingo game cards to the mobile terminal. With such a karaoke device K, multiple users can perform karaoke bingo content using their mobile terminals.

[0115] <Third Embodiment> Next, with reference to Figures 11 to 13, a karaoke system according to the third embodiment will be described. In this embodiment, an example will be described in which the display pattern of bingo game cards is changed using a mobile terminal in the karaoke system shown in the second embodiment. Detailed explanations of configurations similar to those in the first or second embodiment will be omitted.

[0116] ==Karaoke System== Similar to the second embodiment, the karaoke system includes a karaoke device and a portable terminal.

[0117] ==Karaoke Equipment== [Control means] In this embodiment, the CPU executes a dedicated karaoke bingo program stored in memory, and the control means 10e functions as a first extraction unit 101, a second extraction unit 102, a selection unit 103, a reservation processing unit 105, a performance control unit 106, a card distribution unit 108, and a transmission processing unit 109 (see Figure 11).

[0118] (Card Distribution Department) The card distribution unit 108 according to this embodiment generates a bingo game card in which a third predetermined number of words or identifiers corresponding to selected words are placed in the squares, similar to the second embodiment, and distributes the card data corresponding to the bingo game card to the mobile terminal. However, unlike the second embodiment, the card distribution unit 108 according to this embodiment does not generate new bingo game cards. Furthermore, when placing identifiers corresponding to words in the squares of the bingo game card, the card distribution unit 108 generates a table showing the relationship between words and identifiers by assigning different identifiers to the words selected by the selection unit 103, and stores it in the storage means 10a.

[0119] (Transmission processing unit) The transmission processing unit 109 transmits word information to the mobile terminal when a user sings karaoke along with the karaoke performance of a reserved song, and a word selected by the selection unit 103 is input via voice.

[0120] Word information is information that indicates the word that was input via voice or the identifier corresponding to that word. When a word is placed in a square on a bingo game card generated by the card distribution unit 108, the word information becomes the word. On the other hand, when an identifier corresponding to a word is placed in a square on a bingo game card generated by the card distribution unit 108, the word information becomes the identifier corresponding to the word.

[0121] The transmission processing unit 109 compares the words voiced by the user during karaoke singing accompanying the karaoke performance of a reserved song with the words selected by the selection unit 103 to determine whether or not the selected words were voiced. If the words selected by the selection unit 103 are voiced, the transmission processing unit 109 transmits word information indicating the word or an identifier corresponding to the word to the mobile terminal.

[0122] ==Mobile Devices== As shown in Figure 12, the mobile terminal M comprises a storage means 60, a communication means 61, a display means 62, an input means 63, and a control means 64. Each component is connected to bus B via an interface (not shown).

[0123] [Memory means, communication means, display means, input means] The storage means 60 is a storage device for storing various types of data. The communication means 61 provides an interface for communicating with the karaoke device K. The display means 62 is a display for showing various types of information. The input means 63 is configured for the user to input various instructions. Note that the display means 62, which is configured in a touch panel format, may also function as the input means 63.

[0124] [Control means] The control means 64 performs various controls on the mobile terminal M. The control means 64 includes a CPU and memory (neither of which are shown in the figure). The CPU implements various functions by executing programs stored in the memory.

[0125] In this embodiment, when a content application is launched on the mobile terminal M, the control means 64 functions as a display control unit 200.

[0126] (Display Control Unit) The display control unit 200 displays the bingo game card on the display means 62 based on the distributed card data, and if the word indicated by the word information received from the karaoke device K or the identifier corresponding to that word is present on the bingo game card, it changes the display mode of the word or the identifier corresponding to that word, and / or the display mode of the square where the word or the identifier corresponding to that word is located.

[0127] When card data is distributed from the karaoke machine K, the display control unit 200 displays a bingo game card based on the received card data on the display means 62.

[0128] On the other hand, when word information is received from the karaoke device K, the display control unit 200 checks whether the word indicated by the word information or the identifier corresponding to that word is present in the bingo game card. If the word indicated by the word information received from the karaoke device K or the identifier corresponding to that word is present in the bingo game card, the display control unit 200 changes the display mode of the word or the identifier corresponding to that word, and / or the display mode of the square where the word or the identifier corresponding to that word is located. The change in the display mode can be performed by the same process as the process performed by the game control unit 107 in the first embodiment.

[0129] The display control unit 200 repeats the above process until a bingo is achieved (when the display of all words in a row or the identifier corresponding to those words changes). When a bingo is achieved, the display control unit 200 displays the word "Bingo!" on the display means 62. When a bingo is achieved, the display control unit 200 also sends a signal to the karaoke device K to that effect. Upon receiving this signal, the karaoke device K terminates the karaoke bingo content.

[0130] ==Regarding the operation of the karaoke system== Next, with reference to Figure 13, a specific example of the operation of the karaoke system 1 in this embodiment will be described. Figure 13 is a flowchart of an example of the operation of the karaoke system 1. Here, an example using a bingo game card in which identifiers corresponding to words are placed in squares will be explained.

[0131] User U operates the remote control device 50 to select karaoke bingo content. The karaoke device K starts karaoke bingo. The CPU of the control means 10e functions as a first extraction unit 101, a second extraction unit 102, a selection unit 103, a reservation processing unit 105, a performance control unit 106, a card distribution unit 108, and a transmission processing unit 109 by executing a dedicated karaoke bingo program stored in memory. Furthermore, when user U launches the content application on the mobile terminal M, the control means 64 functions as a display control unit 200. By launching the content application on the mobile terminal M, the karaoke device K and the mobile terminal M are connected in a communication-enabled manner.

[0132] The first extraction unit 101 extracts a predetermined number of songs from among the multiple songs stored in the storage means 10a (extracting a predetermined number of songs; step 30). For example, the first extraction unit 101 extracts 500 songs (song X1 to song X500) from among the multiple songs stored in the storage means 10a.

[0133] The second extraction unit 102 extracts each word from the lyrics of the songs extracted in step 30 (extracting each word from the lyrics; step 31). The second extraction unit 102 performs the same processing as in the first embodiment for each of the songs X1 to X500 extracted by the first extraction unit 101, thereby extracting each word from the lyrics of the extracted songs X1 to X500.

[0134] The selection unit 103 selects a second predetermined number of words from the multiple words extracted in step 31 (selection of a second predetermined number of words; step 32). For example, the selection unit 103 selects the word "75" from the multiple words extracted.

[0135] The card distribution unit 108 generates a bingo game card in which identifiers corresponding to a third predetermined number of words from the words selected in step 32 are placed in the squares, and distributes the card data corresponding to the bingo game card to the mobile terminal M (distribution of the bingo game card to the mobile terminal; step 33).

[0136] Specifically, the card distribution unit 108 assigns different identifiers "1 to 75" to the selected "75" words. The card distribution unit 108 stores a table (see Figure 4) showing the relationship between words and identifiers in the storage means 10a. The card distribution unit 108 randomly identifies "24" identifiers from the selected "75" words and generates a bingo game card by arranging the identified identifiers in a 5x5 grid. The card distribution unit 108 distributes the card data corresponding to the generated bingo game card to the mobile terminal M.

[0137] When card data is delivered from the karaoke machine K, the display control unit 200 of the mobile terminal M displays a bingo game card based on the received card data on the display means 62 (display bingo game card; step 34). The display control unit 200 displays, for example, the bingo game card shown in Figure 5A on the display means 62.

[0138] The reservation processing unit 105 reserves the song selected by the user (reserves the song; step 35). Users playing karaoke bingo predict songs that contain words corresponding to the identifier on the displayed bingo game card and select a song via the remote control device 50. The reservation processing unit 105 reserves song X1 by registering the song ID of song X1 selected by the user in the reservation queue.

[0139] The performance control unit 106 controls the performance means 10d to perform karaoke performance of the song reserved in step 35 (karaoke performance of the reserved song; step 36). For example, the performance control unit 106 obtains the accompaniment data for song X1 from the storage means 10a based on the song ID registered in the reservation queue. The performance control unit 106 plays the obtained accompaniment data and controls the performance means 10d to emit karaoke performance sound from the speaker 20. The user U sings karaoke of song X1 using the microphone 40 in time with the karaoke performance sound emitted from the speaker 20.

[0140] The transmission processing unit 109 transmits word information to the mobile terminal when a user sings karaoke accompanied by the karaoke performance of a reserved song and a word selected by the selection unit 103 is input by voice (transmitting word information to the mobile terminal; step 37). For example, the transmission processing unit 109 determines whether the word input by voice during the karaoke performance of user U accompanied by the karaoke performance of the reserved song X1 is a word selected by the selection unit 103. If it is a word selected by the selection unit 103, the transmission processing unit 109 refers to the table of words and identifiers stored in the storage means 10a and transmits word information indicating the identifier corresponding to that word to the mobile terminal M.

[0141] When word information is received from the karaoke device K, the display control unit 200 checks whether an identifier corresponding to the word indicated by the word information exists in the bingo game card.

[0142] If the identifier indicated by the word information received from the karaoke device K is present in the bingo game card displayed in step 34 (i.e., Y in step 38), the display control unit 200 changes the display mode of the identifier corresponding to that word (change the display mode of the identifier; step 39).

[0143] Specifically, let's assume that the word information transmitted from the karaoke machine K was identifier "3" corresponding to the word "dark night". The display control unit 200 checks whether the bingo game card being displayed has the identifier indicated by the received word information. The bingo game card in Figure 5A has identifier "3". Therefore, the display control unit 200 changes the display of identifier "3" and displays the word "dark night" instead of identifier "3" (see Figure 5B).

[0144] The karaoke system 1 repeatedly performs the processes from step 35 to step 39 until the display pattern of all the identifiers in a row of the bingo game card distributed to the mobile terminal M changes and a bingo is achieved (until it becomes Y in step 40).

[0145] As is clear from the above, the karaoke system 1 according to this embodiment includes a karaoke device K and a portable terminal M. The karaoke device K includes: a first extraction unit 101 that extracts a first predetermined number of songs from a plurality of songs stored in the storage means 10a; a second extraction unit 102 that extracts words from the lyrics of the extracted songs word by word; a selection unit 103 that selects a second predetermined number of words from the plurality of extracted words; a card distribution unit 108 that generates a bingo game card in which a third predetermined number of words or identifiers corresponding to those words are placed in squares from the selected words or identifiers corresponding to those words, and distributes card data corresponding to the bingo game card to the mobile terminal M; a reservation processing unit 105 that reserves songs selected by the user; a performance control unit 106 that controls the performance means 10d to perform karaoke performance of the reserved songs; and a transmission processing unit 109 that, when a voice input of a word selected by the selection unit 103 is received during the user's karaoke singing accompanying the karaoke performance of the reserved songs, transmits word information indicating the word or the identifier corresponding to that word to the mobile terminal M. The mobile terminal M displays a bingo game card on the display means 62 based on the distributed card data, and has a display control unit 200 that changes the display mode of the word or the identifier corresponding to the word, and / or the display mode of the square where the word or the identifier corresponding to the word is located, if the word indicated by the word information received from the karaoke device K is present on the bingo game card.

[0146] According to this karaoke system 1, a bingo game card can be generated with words from the song lyrics or identifiers corresponding to those words placed in squares, and this card can be delivered to the user's mobile device. Furthermore, the mobile device can change the display of the bingo game card in accordance with the karaoke singing. Therefore, the user can check the bingo game card on their mobile device. In other words, according to the karaoke system 1 of this embodiment, a new content combining karaoke singing and a bingo game can be implemented.

[0147] <Modified form of the third embodiment> The above example described a scenario where one user participates in the karaoke bingo content on a single karaoke system. However, it is also possible for multiple users to participate in the karaoke bingo content on a single karaoke system.

[0148] In this case, for example, a bingo game card can be created as in the above embodiment and distributed to each user's mobile device. Then, multiple users can play the bingo game by taking turns singing karaoke.

[0149] On the other hand, when a karaoke system implements content that combines karaoke singing and a bingo game with multiple users, the card distribution unit 108 can generate multiple bingo game cards according to the number of users and distribute the card data corresponding to the bingo game cards to each user's mobile terminal. In addition, the transmission processing unit 109 can transmit word information to each user's mobile terminal.

[0150] For example, when four users play karaoke bingo, one user operates the remote control device 50 and inputs the number of users, "4". The card distribution unit 108 generates four types of bingo game cards according to the input number of users, "4". It is assumed that each user is running the content application on their mobile device. When the mobile device starts the content application, it sends its own device ID to the karaoke device K.

[0151] The card distribution unit 108 associates one terminal ID with each of the four types of bingo game cards it has generated. The card distribution unit 108 then distributes the card data corresponding to the bingo game cards to the mobile terminals according to the terminal IDs associated with the bingo game cards.

[0152] Furthermore, the transmission processing unit 109 determines whether the word voiced during the user's karaoke singing accompanying the karaoke performance of the reserved song is a word selected by the selection unit 103. If it is a word selected by the selection unit 103, the transmission processing unit 109 transmits word information indicating the word or an identifier corresponding to the word to each mobile terminal. The display control unit 200 in each mobile terminal performs the same processing as described in the third embodiment.

[0153] As is clear from the above, in the karaoke system 1 according to this modified example, when multiple users perform content that combines karaoke singing and a bingo game, the card distribution unit 108 generates multiple bingo game cards according to the number of users, distributes the card data corresponding to the bingo game cards to each user's mobile terminal, and the transmission processing unit 109 transmits word information to each user's mobile terminal. With such a karaoke system 1, multiple users can perform karaoke bingo content using their mobile terminals.

[0154] <Example 1> In the above embodiment and modified configuration, the first extraction unit 101 can extract a first predetermined number of songs that satisfy predetermined conditions.

[0155] The predetermined conditions are the conditions for extracting a song from among multiple songs stored in the storage means 10a.

[0156] Specifically, the genre of the song and the name of the artist can be set as predetermined conditions. For example, a user playing karaoke bingo selects the genre of the song as a condition for extracting songs via the remote control device 50 or the like. The first extraction unit 101 refers to the attribute information for each song stored in the storage means 10a and identifies songs whose attribute information includes the genre of the song selected by the user. The first extraction unit 101 extracts a predetermined number of songs from the songs of the selected genre.

[0157] Alternatively, the system may require that the songs be included in a national karaoke ranking (for example, a list compiled in descending order of the number of times a song has been sung in karaoke machines nationwide over the past six months) or in the user's singing history (a list recording the date and time the user sang karaoke, the song title, the scoring result, etc.) obtained from an external server device (not shown). In this case, the first extraction unit 101 can refer to the national karaoke ranking or the user's singing history and extract a predetermined number of songs randomly or in descending order of the number of times they have been sung. The first extraction unit 101 may also extract a predetermined number of songs according to the difficulty level of the karaoke bingo selected by the user via the remote control device 50 or the like. For example, if the first extraction unit 101 is set to a first predetermined number of 300 songs, it can extract songs ranked 1st to 300th in terms of the number of times sung when the difficulty level is "low", extract songs ranked 301st to 600th in terms of the number of times sung when the difficulty level is "medium", and extract songs ranked 601st to 900th in terms of the number of times sung when the difficulty level is "high".

[0158] Furthermore, multiple conditions may be set as predetermined conditions. For example, the genre of the song and the artist's name may be predetermined conditions, or the genre of the song and inclusion in the national rankings may be predetermined conditions.

[0159] If the first extraction unit 101 extracts a predetermined number of songs that satisfy predetermined conditions, the reservation processing unit 105 reserves only the songs that satisfy the predetermined conditions.

[0160] For example, suppose the first extraction unit 101 extracts a predetermined number of songs that satisfy the genre "anime song". In this case, the reservation processing unit 105 refers to the attribute information of the songs selected by the user and checks whether the selected songs belong to the genre "anime song". If the selected songs belong to the genre "anime song", the reservation processing unit 105 reserves the songs by registering the song identification information of those songs in the reservation queue. On the other hand, if the songs do not belong to the genre "anime song", the reservation processing unit 105 does not register the song identification information of those songs in the reservation queue (i.e., does not reserve the songs). If the songs are not reserved, the reservation processing unit 105 may display a message to that effect to the user. For example, the reservation processing unit 105 may display the message "This song does not meet the set predetermined conditions" on the display device 30, or emit the message from the speaker 20.

[0161] In this modified configuration, the first extraction unit 101 extracts a predetermined number of songs that satisfy predetermined conditions, and the reservation processing unit 105 reserves only the songs that satisfy the predetermined conditions. With this configuration, only songs that satisfy the predetermined conditions are extracted. In other words, the range of words used on the bingo game cards is limited. Therefore, users can enjoy the karaoke bingo content by focusing on songs that are easy to sing at karaoke or songs that are frequently sung at karaoke.

[0162] <Modification 2> In the above embodiment and modified configuration, the second extraction unit 102 can extract each word from the lyrics of a predetermined singing section of the extracted song.

[0163] A predetermined singing section may be a single singing section such as the A section, chorus, and B section of the first verse, or multiple singing sections such as "one chorus (A section, B section, and chorus of the first verse)." A predetermined singing section may be set in advance for each Karaoke Bingo content, or the user may set any singing section via the remote control device 50 each time they perform Karaoke Bingo content.

[0164] For example, if "one chorus" is set as a predetermined singing section, the second extraction unit 102 reads the lyrics data of a song extracted by the first extraction unit 101 from the storage means 10a and extracts the words contained in the lyrics corresponding to the singing sections of the first verse, pre-chorus, and chorus.

[0165] When the second extraction unit 102 extracts words from the lyrics of a predetermined singing section of a song, the performance control unit 106 controls the performance means 10d to perform karaoke playback only for the predetermined singing section of the reserved song.

[0166] For example, if the second extraction unit 102 extracts each word from the lyrics of "one chorus" of a song, the performance control unit 106 controls the performance means 10d to perform karaoke playback of only "one chorus" of the reserved song's singing section.

[0167] As described above, the second extraction unit 102 in this modified example extracts words from the lyrics of a predetermined singing section of the extracted song, word by word, and the performance control unit 106 controls the performance means 10d to perform karaoke only the predetermined singing section of the reserved song. With this configuration, only words from the lyrics of a portion of the song's singing section are extracted. Furthermore, the karaoke performance of the song is limited to that portion of the singing section. As a result, the karaoke performance for each song is shortened, allowing users to enjoy bingo while singing karaoke to various songs.

[0168] <Variation 3> In the above embodiment and modified configuration, the selection unit 103 can select a second predetermined number of words according to the number of songs containing each word determined for that word.

[0169] In this case, the second extraction unit 102 determines the number of songs containing each word, as described in the first embodiment. The selection unit 103 checks the number of songs for each word and can select a second predetermined number of words in descending order of frequency.

[0170] Alternatively, the selection unit 103 may select words according to the difficulty level of the karaoke bingo selected by the user via the remote control device 50 or the like. For example, if the difficulty level is "low," the selection unit 103 may select a second predetermined number of words in descending order of the number of songs; if the difficulty level is "medium," it may select a second predetermined number of words from the top 20-50% of words in terms of the number of songs; and if the difficulty level is "high," it may select a second predetermined number of words in descending order of the number of songs.

[0171] In this modified example, the selection unit 103 can select a second predetermined number of words according to the number of songs containing each word determined for that word. With this configuration, the words to be used on the bingo game cards can be determined according to the number of songs containing each word.
