[0006] During an infectious disease epidemic, karaoke parlors may voluntarily suspend operations and users may avoid singing karaoke, causing many users to become estranged from singing karaoke. Even when the infectious disease epidemic subsides and users are able to sing karaoke again, it may take time for users to get into karaoke rhythm because it has been a long time since their last karaoke performance. Therefore, if users use karaoke singing scoring content after a long break and are not in rhythm, their scoring results may be poor, preventing users from enjoying karaoke singing. As a result, there is a risk that users may once again become estranged from singing karaoke.

[0007] To provide a karaoke machine that allows a user to enjoy singing karaoke comfortably without the score being poor even when the karaoke singing is scored after a long break. [Means for solving the problem]

[0008] In order to solve the above problems, the karaoke device of the present invention is characterized by having an evaluation unit that evaluates the karaoke singing performed by a user in accordance with a karaoke performance of a song and outputs a scoring result, an acquisition unit that acquires the user's karaoke singing history, an identification unit that determines the number of days that have passed since the last karaoke singing based on the singing history, and a correction unit that adds points to the scoring result based on the number of days that have passed. [Effects of the Invention]

[0009] According to the present invention, even when karaoke singing is scored after a long break, the scoring result will not be poor and karaoke singing can be enjoyed comfortably. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] [First embodiment] A karaoke device 1 according to a first embodiment of the present invention will now be described.

[0012] [Karaoke equipment] Fig. 1 is a block diagram showing the configuration of a karaoke device 1 according to a first embodiment. As shown in Fig. 1, the karaoke device 1 includes a karaoke main unit 2, a microphone 3, a speaker 4, a display device 5 such as a monitor, and a remote control device 6. The karaoke device 1 is installed in an installation location such as a karaoke room. The karaoke device 1 is communicably connected to an external server device 7 to form a karaoke system 100.

[0013] The karaoke machine main unit 2 is connected by wire or wirelessly to a microphone 3, a speaker 4, a display device 5, and a remote control device 6. The microphone 3 converts the user's singing voice into an audio signal and inputs it to the karaoke machine main unit 2. The speaker 4 emits the user's singing voice along with the karaoke performance of the song based on the sound emission signal from the karaoke machine main unit 2. The display device 5 displays various screens based on the video signal etc. from the karaoke machine main unit 2, for example, displaying lyrics captions along with background images in time with the karaoke performance.

[0014] The remote control device 6 is mainly composed of a touch panel. The remote control device 6 displays various screens and various operation buttons on the touch panel, and also accepts login operations and song selection (reservation) operations via the touch panel. The remote control device 6 and the karaoke main unit 2 are paired via wireless communication, allowing various information to be transmitted and received between them.

[0015] The remote control device 6 transmits user identification information (user ID) and the like input in response to the user's login operation to the karaoke main unit 2. The remote control device 6 accepts song searches and song selections (reservations), and transmits song identification information (song ID) of the song selected in response to the user's song selection operation to the karaoke main unit 2 as reserved song information.

[0016] The karaoke unit 2 has a function of not only performing karaoke performance of the selected songs, but also evaluating the singing voice of the user singing karaoke.

[0017] The karaoke main unit 2 includes a control unit 10, a memory unit 11, a sound source 12, and an audio input / output unit 13. The control unit 10 includes a CPU (Central Processing Unit) and other components, and controls the karaoke main unit 2. The memory unit 11 includes storage media such as a ROM (Read Only Memory), RAM (Random Access Memory), and HDD (Hard Disc Drive), and stores programs and data for controlling each unit and function of the karaoke device 1.

[0018] For example, the storage unit 11 stores the user ID of each user of the karaoke machine 1 to identify each user. The control unit 10 receives the user ID entered in response to the user's login operation from the remote control device 6 and confirms that the received user ID is stored in the storage unit 11, thereby accepting the user's login. This allows the user to log in to the karaoke machine 1 or to the karaoke system 100 to which the karaoke machine 1 belongs.

[0019] The storage unit 11 also stores basic information such as the song ID, song title, singer name, and genre for each song that can be karaoke-played by the karaoke device 1. The storage unit 11 also stores song data for each song, including performance data, reference data, and lyric data. The storage unit 11 also stores a reservation list for sequentially registering reserved song information for songs reserved on the karaoke device 1. The storage unit 11 also stores, for each user of the karaoke device 1, the song IDs of songs performed by that user in association with the logged-in user ID as the singing history of that user. The singing history also includes information such as the date of the karaoke performance and the identification information of the karaoke device 1 on which the karaoke performance was performed.

[0020] In the song data, performance data is MIDI format data that serves as the basis for the accompaniment sounds of a karaoke performance. Reference data is pitch information used as a standard for evaluating a user's karaoke singing. Lyric data is data that serves as the basis for the lyric captions displayed on the display device 5. Note that a song to be performed as karaoke is made up of multiple singing sections, and the song data includes singing section information for each singing section. Note that a song has performance sections (non-singing sections) before and / or after each singing section, and the song data also includes performance section information for each performance section.

[0021] The sound source 12 is a karaoke performance means, which is composed of, for example, a MIDI sound source, and generates a performance signal for a karaoke performance based on the performance data of the song data. When the control unit 10 reads out the song data corresponding to the songs from the storage unit 11 in the order in which the songs are registered in the reservation list of the storage unit 11, the sound source 12 generates a performance signal based on the performance data of the read song data and outputs it to the audio input / output unit 13.

[0022] The audio input / output unit 13 is comprised of a mixer (digital mixer), an amplifier, etc., and mixes the karaoke performance signal and the karaoke singing audio signal, and amplifies this mixed signal to be output from the speaker 4. The volume levels of the karaoke performance signal and the singing audio signal reflect the music volume setting made by the user. For example, the audio input / output unit 13 is connected to the sound source 12 and inputs the performance signal from the sound source 12, and is also connected to the microphone 3 and inputs the audio signal from the microphone 3. The audio input / output unit 13 is connected to the speaker 4 and outputs a mixed signal of the performance signal and the audio signal to the speaker 4.

[0023] The control unit 10 controls each unit and function of the karaoke device 1 by executing calculations based on the programs and data stored in the storage unit 11. For example, the control unit 10 of this embodiment executes the programs stored in the storage unit 11 to operate as an evaluation unit 20, an acquisition unit 21, a determination unit 22, a correction unit 23, and a notification unit 24, and has the function of evaluating karaoke singing and outputting the scoring results.

[0024] The evaluation unit 20 evaluates the singing voice of the user singing karaoke along with the karaoke performance of the song, calculates and outputs the scoring result. Specifically, the evaluation unit 20 acquires the karaoke singing audio signal input from the microphone 3 during the karaoke performance via the audio input / output unit 13. The evaluation unit 20 also uses known technology to compare the karaoke singing audio signal with reference data of the song data stored in the storage unit 11, and calculates the scoring result of the singing voice by evaluating the accuracy of the singing pitch, singing technique, etc. on a scale of 100 points. The evaluation unit 20 may evaluate and score the singing voice for each singing section of the song, and calculate the scoring result of the karaoke singing based on the scoring results for all singing sections (for example, by calculating the average value).

[0025] When a user logs in to the karaoke device 1 or the karaoke system 100 by inputting a user ID using a remote control device 6, the acquisition unit 21 acquires the singing history of the user's past karaoke singing from the storage unit 11 based on the logged-in user ID.

[0026] The determination unit 22 determines the number of days that have elapsed since the user's last karaoke performance to the current karaoke performance, based on the user's singing history acquired by the acquisition unit 21. For example, the determination unit 22 determines the number of days that have elapsed based on the number of days between the date information of the last (most recent) stored singing history among the singing history stored during the user's previous logins and the date of the current login. Alternatively, the karaoke device 1 may store the login date of each user, and the determination unit 22 may determine the number of days that have elapsed based on the number of days between the last login date when the user logged in to the karaoke system 100 and performed karaoke, and the date of the current login.

[0027] The correction unit 23 corrects the score of the karaoke singing evaluated by the evaluation unit 20 by adding points based on the number of days elapsed since the user's last karaoke singing performance identified by the identification unit 22. For example, the correction unit 23 determines whether the number of days elapsed satisfies a predetermined elapsed condition, and if the predetermined elapsed condition is met, corrects the score of the karaoke singing performance by adding a predetermined number of points. Here, the predetermined elapsed condition is set to the number of days elapsed being equal to or greater than a predetermined threshold number of days (e.g., six months), and the predetermined number of points is set to a predetermined fixed value (e.g., 10 points). Alternatively, the predetermined number of points may be set using a predetermined coefficient, for example, the score multiplied by the coefficient (e.g., 0.1). The correction unit 23 also corrects the score of other karaoke singing performances performed by the user on the same day by adding points.

[0028] In addition, it is desirable for the correction unit 23 to add points to the scoring result so that the scoring result after adding points is less than or equal to a predetermined upper limit of added points.For example, it is desirable to add points so that the scoring result after adding points is less than or equal to 95.0 points or less than 100 points.

[0029] The notification unit 24 notifies the user of the scoring result of the karaoke singing evaluated by the evaluation unit 20. When the correction unit 23 adds points to the scoring result, the notification unit 24 notifies the user of the corrected scoring result. The notification unit 24 may display a screen notifying the scoring result on the display device 5 or the remote control device 6, or may cause the speaker 4 to emit a synthesized voice notifying the scoring result.

[0030] [Evaluation Operation of the First Embodiment] Next, in the first embodiment, an example of an evaluation operation in which the karaoke device 1 evaluates the karaoke singing of the song X1 when the user U sings the karaoke song after a predetermined blank period has elapsed will be described with reference to Fig. 2. Fig. 2 is a flowchart showing an example of the evaluation operation of the karaoke device 1 in the first embodiment.

[0031] In this example, it is assumed that on May 31, 2021, user U logged into the karaoke system 100 to which the karaoke device 1 belongs and performed karaoke using the karaoke device 1. At this time, the karaoke device 1 stores in the storage unit 11 a singing history including date information of May 31, 2021 for the song that was performed karaoke.

[0032] After that, due to the outbreak of the infectious disease, user U is assumed to have been away from singing karaoke using karaoke device 1 for more than six months. Then, after a blank period of more than six months has passed since the outbreak of the infectious disease subsided, user U enters a karaoke room in which karaoke device 1 is installed on January 5, 2022, and enters his / her user ID using remote control device 6 to log in to karaoke system 100 to which karaoke device 1 belongs.

[0033] When the user U logs in to the karaoke system 100, the acquisition unit 21 acquires the singing history of the user U from the storage unit 11 based on the user ID of the user U (step S101).

[0034] Furthermore, the determination unit 22 determines the number of days D that have elapsed since the user U's last karaoke singing to the current karaoke singing, based on the singing history of the user U acquired by the acquisition unit 21 (step S102). In this example, the date information of the most recently stored singing history of the user U stored in the storage unit 11 is May 31, 2021, the date when the user U last logged in to the karaoke system 100, so the determination unit 22 determines the date of the last karaoke singing to be May 31, 2021. Furthermore, the date when the user U last logged in to the karaoke system 100 is January 5, 2022, so the determination unit 22 determines the date when the current karaoke singing will be performed to be January 5, 2022. Then, the determination unit 22 determines the number of elapsed days D as "7 months + 4 days" based on the number of days between the last karaoke singing on May 31, 2021 and the current karaoke singing on January 5, 2022.

[0035] When user U currently logged into karaoke system 100 reserves song X using remote control device 6, remote control device 6 transmits the song ID of song X as reserved song information to karaoke main unit 2. In karaoke main unit 2, control unit 10 registers the song ID of song X included in the received reserved song information in a reservation list in storage unit 11. Control unit 10 also reads out song data of song X registered in the reservation list from storage unit 11, generates a performance signal for song X based on performance data of this song data using sound source 12, and outputs the performance signal for song X to speaker 4 via audio input / output unit 13 to emit sound, thereby starting the karaoke performance of song X (step S103).

[0036] When a user U sings karaoke using a microphone 3 during the karaoke performance of a piece of music X, the singing voice of the user U is input to an audio input / output unit 13, which outputs an audio signal of the singing voice to a speaker 4 to emit the voice, and the singing voice of the user U is emitted from the speaker 4 together with the karaoke performance of the piece of music X.

[0037] At this time, the evaluation unit 20 compares the audio signal of the singing voice of the user U output from the audio input / output unit 13 with the reference data of the music data of the music piece X, evaluates and scores the singing voice of the user U based on the comparison result, and outputs the scoring result P (step S104). In this example, the evaluation unit 20 outputs the scoring result P in which the karaoke singing of the music piece X by the user U is scored as "72.5" points.

[0038] The correction unit 23 determines whether the number of days D since the user U last sang karaoke, identified by the identification unit 22, satisfies a predetermined elapsed condition (step S105). In this example, the number of days D, "7 months + 4 days," satisfies the predetermined elapsed condition of 6 months or more (step S105: YES). Therefore, the correction unit 23 corrects the score P of the user U's karaoke singing of the song X, evaluated by the evaluation unit 20, by adding a predetermined score P_add (step S106), and outputs the corrected score P to the notification unit 24.

[0039] In this example, when the predetermined score P_add is a fixed value of "10.0", the correction unit 23 adds "10.0" of the predetermined score P_add to "72.5" of the score P, thereby correcting the score P to "72.5+10.0=82.5". Alternatively, when the predetermined score P_add is the result of multiplying the original score P by a predetermined coefficient R_add (for example, "0.10"), the correction unit 23 calculates "72.5×0.10=7.25" as the predetermined score P_add based on the original score P and the predetermined coefficient R_add, and adds "7.25" of the predetermined score P_add to "72.5" of the score P, thereby correcting the score P to "72.5+7.25=79.75".

[0040] If the number of elapsed days D does not satisfy the predetermined elapsed condition (step S105: NO), the correction unit 23 outputs the scoring result P to the notification unit 24 without correcting it.

[0041] The notification unit 24 notifies the user U of the score P of the karaoke singing of the song X by the user U, which has been evaluated by the evaluation unit 20 and corrected by the correction unit 23, by displaying or audibly (step S107).

[0042] As described above, according to the first embodiment of the present invention, the karaoke device 1 includes an evaluation unit 20 that evaluates the karaoke singing performed by the user in sync with the karaoke performance of a song and outputs a scoring result, an acquisition unit 21 that acquires the user's karaoke singing history, an identification unit 22 that identifies the number of days that have passed since the last karaoke singing based on the singing history, and a correction unit 23 that adds points to the scoring result based on the number of days that have passed.

[0043] As a result, even when a user is away from singing karaoke in a karaoke room due to an epidemic or the like and his / her karaoke singing is scored after a long break, the scoring result will not be poor due to the break, and the user can enjoy singing karaoke comfortably. [Variations]

[0044] In the above embodiment, the correction unit 23 sets the predetermined points to be added to the scoring result of the user's karaoke singing based on a fixed value or a predetermined coefficient, but the present invention is not limited to this example. As a modified example, the correction unit 23 may set the predetermined points P_add to be added to the scoring result P according to the number of days D that have passed since the user's last karaoke singing and the current karaoke singing. For example, the longer the number of days D, the larger the predetermined points P_add is set.

[0045] Specifically, the correction unit 23 may calculate a difference value D_dif between the number of elapsed days D and a predetermined threshold number of days (e.g., six months) of a predetermined elapsed condition, and set the predetermined score P_add as a function of the difference value D_dif. Alternatively, the correction unit 23 may predefine a table associating the predetermined score P_add with the difference value D_dif and store the table in the storage unit 11, as shown in Fig. 3, and read out the predetermined score P_add from the table according to the difference value D_dif.

[0046] Thus, even when karaoke singing is scored after a longer blank, the scoring result is corrected according to the length of the blank, so that the blank does not cause the scoring result to deteriorate, and the user can enjoy singing karaoke comfortably.

[0047] In addition, in the above embodiment, the identification unit 22 determines the period from the user's last karaoke singing to the current karaoke singing as the number of elapsed days, and the correction unit 23 determines that the number of elapsed days being equal to or greater than a predetermined threshold number of days (e.g., 6 months) is the predetermined elapsed condition for adding points to the scoring result of the karaoke singing, but the present invention is not limited to this example.

[0048] As a modified example, the determination unit 22 may determine, as the number of elapsed days, the longest period between the login dates of the most recent fixed number of times (for example, four times) that the user logged in to the karaoke system 100 and performed karaoke. In this case, if the most recent fixed number of times is four, the determination unit 22 determines, as the number of elapsed days, the longest period among the period between the third login date and the second login date, the period between the second login date and the previous (previous) login date, and the period between the previous login date and the current login date.

[0049] For example, as shown in Figure 4, a user logs in on May 7, 2021, May 16, 2021, May 24, 2021, May 31, 2021, January 5, 2022, January 6, 2022, January 8, 2022, and January 11, 2022, and the karaoke device 1 stores each login date in the memory unit 11.

[0050] Here, when a user logs in on May 31, 2021 as the current date, and the login date three logins ago was May 7, 2021, the identification unit 22 determines the period between the login date three logins ago, May 7, 2021, and the login date two logins ago, May 16, 2021, as 8 days, the period between the login date two logins ago, May 16, 2021, as 7 days, and the previous login date, May 24, 2021, as 6 days, and determines the longest of these, 8 days, as the number of elapsed days. In this case, the number of elapsed days of 8 days is less than the day threshold of 6 months, so the scoring result is not added.

[0051] Furthermore, when a user logs in on January 5, 2022 as the current date, and the login date three logins ago was May 16, 2021, the identification unit 22 determines the period between the login date three logins ago, May 16, 2021, and the login date two logins ago, May 24, 2021, as 7 days, the period between the login date two logins ago, May 24, 2021, and the previous login date, May 31, 2021, as 6 days, and the period between the previous login date, May 31, 2021, and the current login date, January 5, 2022, as 7 months and 4 days, and identifies the longest of these, 7 months and 4 days, as the number of elapsed days. In this case, since the number of elapsed days of 7 months and 4 days is greater than the day threshold of 6 months, the scoring result is added. Similarly, if a user logs in on January 6, 2022 or January 8, 2022, the number of days that have passed will be greater than or equal to the threshold, and the scoring result will be added.

[0052] Furthermore, when a user logs in on January 11, 2022 as the current date, the third login date before that is January 5, 2022, and therefore the identification unit 22 determines the period between the third login date before that, January 5, 2022, and the second login date before that, January 6, 2022, as 0 days, the period between the second login date before that, January 6, 2022, as 1 day, and the period between the last login date, January 8, 2022, and the current login date, January 11, 2022, as 2 days, and identifies the longest of these, 2 days, as the number of elapsed days. In this case, since the number of elapsed days of 2 days is less than the day threshold of 6 months, the scoring result is not added.

[0053] In this way, if the number of times karaoke is sung after a gap is less than the predetermined number of times in the immediate future, the determination unit 22 can determine the number of days that have passed by taking into account the number of days since the last karaoke song before the gap.If the user sings karaoke several times at short intervals after a gap (for example, every few days (1 to 3 days, etc.) or every few days (1 week, etc.)), the correction unit 23 can determine that the predetermined elapsed condition is met and add this to the scoring result of the karaoke singing.

[0054] As a result, even if a user sings karaoke a predetermined number of times after a long break, the scoring result will not be deteriorated due to the break, and the user can enjoy singing karaoke comfortably.

[0055] In addition, when the number of karaoke songs sung after the break reaches a predetermined number of times in the immediate future, the determination unit 22 determines the number of days that have passed without considering the number of days since the karaoke song sung before the break. Therefore, even if the user sings karaoke at short intervals, the correction unit 23 determines that the predetermined elapsed condition is not met and does not add it to the scoring result of the karaoke singing.

[0056] [Second embodiment] A karaoke device 1 according to a second embodiment of the present invention will be described below. In the description of the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0057] In the karaoke device 1 of the second embodiment, as in the first embodiment, the control unit 10 executes the program stored in the storage unit 11 to operate as the evaluation unit 20, acquisition unit 21, identification unit 22, correction unit 23, and notification unit 24. In the second embodiment, the correction unit 23 is configured to add points to the score for the karaoke singing of only a predetermined number of songs (e.g., three songs) in the order of the karaoke performance. In other words, the correction unit 23 adds points to the score for the karaoke singing of a song only if the song order of the songs to be karaoke performed is within a predetermined order (e.g., three).

[0058] [Evaluation Operation of the Second Embodiment] Next, in the second embodiment, an example of an evaluation operation in which the karaoke device 1 evaluates the karaoke singing of songs X1, X2, X3, X4, and X5 performed by a user U after a predetermined blank period will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of the evaluation operation of the karaoke device 1 in the second embodiment.

[0059] In this example, it is assumed that user U logs in to the karaoke system 100 to which the karaoke device 1 belongs after "7 months + 4 days" have passed since the last karaoke performance. The acquisition unit 21 acquires user U's singing history from the storage unit 11 based on user U's user ID (step S201), and the identification unit 22 identifies the number of days D that have passed since user U's last karaoke performance to the current karaoke performance as "7 months + 4 days" based on user U's singing history (step S202).

[0060] When the user U reserves songs X1, X2, X3, X4, and X5 using the remote control device 6, the control unit 10 of the karaoke main unit 2 sequentially registers the reserved song information of songs X1, X2, X3, X4, and X5 in a reservation list in the storage unit 11. The control unit 10 also sequentially reads out the song data of songs X1, X2, X3, X4, and X5 registered in the reservation list from the storage unit 11, and the sound source 12 and the audio input / output unit 13 perform karaoke performances of songs X1, X2, X3, X4, and X5 in the order in which they were reserved (step S203).

[0061] First, the user U sings karaoke using the microphone 3 along with the karaoke performance of the song X1, and the evaluation unit 20 evaluates the user U's karaoke singing of the song X1 and outputs the scoring result P1 scoring "72.5" points (step S204).

[0062] The correction unit 23 adds a fixed value of "10.0" points as a predetermined score P_add to the scoring result P1 of user U's karaoke singing of song X1, and corrects the scoring result P1 to "72.5 + 10.0 = 82.5" points (step S207), because the number of days D that have passed since user U's last karaoke singing, "7 months + 4 days," meets the predetermined elapsed condition of 6 months or more (step S205: YES), and the karaoke performance of song X1 is the first song, that is, it meets the predetermined number of songs (e.g., 3 songs) in the order of karaoke performance (step S206: YES).

[0063] The notification unit 24 notifies the user U of the score P1 of "82.5" points, which is the score evaluated by the evaluation unit 20 and corrected by the correction unit 23, for the user U's karaoke singing of the song X1 (step S208). After the karaoke performance of the song X1, reserved songs X2, X3, X4, and X5 remain (step S209: YES), so the karaoke performance of the next song, X2, begins (step S203).

[0064] Next, the user U sings karaoke using the microphone 3 along with the karaoke performance of the song X2, and the evaluation unit 20 evaluates the karaoke singing of the song X2 by the user U and outputs the scoring result P2 scoring it as "78.0" points (step S204).

[0065] The correction unit 23 adds a fixed value of "10.0" points as a predetermined score P_add to the scoring result P2 of user U's karaoke singing of song X2, and corrects the scoring result P2 to "78.0 + 10.0 = 88.0" points (step S207), because the number of days D that have passed since user U's last karaoke singing, "7 months + 4 days," meets the predetermined elapsed condition of 6 months or more (step S205: YES), and the karaoke performance of song X2 is the second song, that is, it meets the predetermined number of songs (e.g., 3 songs) in the order of karaoke performance (step S206: YES).

[0066] The notification unit 24 notifies the user U of the score P2 of "88.0" points, which is the score evaluated by the evaluation unit 20 and corrected by the correction unit 23, for the user U's karaoke singing of the song X2 (step S208). After the karaoke performance of the song X2, reserved songs X3, X4, and X5 remain (step S209: YES), so the karaoke performance of the next song, X3, begins (step S203).

[0067] Next, the user U sings karaoke using the microphone 3 along with the karaoke performance of the song X3, and the evaluation unit 20 evaluates the karaoke singing of the song X3 by the user U and outputs the scoring result P3 scoring it as "81.5" points (step S204).

[0068] The correction unit 23 adds a fixed value of "10.0" points as a predetermined score P_add to the scoring result P3 of user U's karaoke singing of song X3, and corrects the scoring result P3 to "81.5 + 10.0 = 91.5" points (step S207), because the number of days D that have passed since user U's last karaoke singing, "7 months + 4 days," meets the predetermined elapsed condition of 6 months or more (step S205: YES), and the karaoke performance of song X3 is the third song, that is, it meets the predetermined number of songs (e.g., 3 songs) in the order of karaoke performance (step S206: YES).

[0069] The notification unit 24 notifies the user U of the score P3 of "91.5" which is the score evaluated by the evaluation unit 20 and corrected by the correction unit 23 for the user U's karaoke singing of the song X3 (step S208). After the karaoke performance of the song X3, the reserved songs X4 and X5 remain (step S209: YES), so the karaoke performance of the next song X4 begins (step S203).

[0070] Next, the user U sings karaoke using the microphone 3 along with the karaoke performance of the song X4, and the evaluation unit 20 evaluates the user U's karaoke singing of the song X4 and outputs a scoring result P4 scoring "89.5" points (step S204).

[0071] The correction unit 23 determines that the number of days D since the user U's last karaoke performance, "7 months + 4 days," satisfies the predetermined elapsed condition of 6 months or more (step S205: YES), but does not make any additional correction to the scoring result P4 of the user U's karaoke singing of song X4 because the karaoke performance of song X4 is the fourth song, i.e., it does not satisfy the condition that the number of songs in the karaoke performance order is within the predetermined number (e.g., 3 songs) (step S206: NO).

[0072] The notification unit 24 notifies the user U of "89.5 points," which is the unadjusted score P4 evaluated by the evaluation unit 20 for the user U's karaoke singing of song X4 (step S208). After the karaoke performance of song X4, reserved song X5 remains (step S209: YES), so the karaoke performance of the next song X5 begins (step S203).

[0073] Next, the user U sings karaoke using the microphone 3 along with the karaoke performance of the song X5, and the evaluation unit 20 evaluates the karaoke singing of the song X5 by the user U and outputs the scoring result P5 scoring it as "90.0" points (step S204).

[0074] The correction unit 23 determines that the number of days D since the user U's last karaoke performance, "7 months + 4 days," satisfies the predetermined elapsed condition of 6 months or more (step S205: YES), but does not make any additional correction to the scoring result P5 of the user U's karaoke singing of song X5 because the karaoke performance of song X5 is the fifth song, i.e., it does not satisfy the condition that the number of songs in the karaoke performance order is within the predetermined number (e.g., 3 songs) (step S206: NO).

[0075] The notification unit 24 notifies the user U of "90.0" points, which is the uncorrected score P5 evaluated by the evaluation unit 20 for the user U's karaoke singing of song X5 (step S208). After the karaoke performance of song X5, there are no reserved songs remaining (step S209: NO), so the operation ends.

[0076] When a user starts singing karaoke after a long break, they may feel out of tune at first, but gradually regain their rhythm as they sing a few songs. According to the second embodiment, points are added to the scoring result during the predetermined number of songs until the user regains their rhythm, so the scoring result is not affected by the break, allowing the user to enjoy singing karaoke comfortably. Furthermore, after the user regains their rhythm after singing a predetermined number of karaoke songs, their karaoke singing is scored as usual, allowing the user to enjoy singing karaoke.

[0077] In the second embodiment, the correction unit 23 adds a fixed value of "10.0" points as the predetermined score P_add to each of the songs within the predetermined number of songs in the karaoke performance order, but the present invention is not limited to this example. In another example, the correction unit 23 may set different predetermined scores P_add for each of the songs within the predetermined number of songs depending on the karaoke performance order, and in this case, the predetermined scores P_add may be set to be smaller in the karaoke performance order, in other words, the earlier the karaoke performance order, the larger the predetermined score P_add may be set.

[0078] For example, taking the songs X1, X2, and X3 described in the evaluation operation of the karaoke device 1 of the second embodiment above as an example, the correction unit 23 may set the predetermined score P_add1 for the scoring result P1 of the karaoke singing of the first song X1 to "10.0," the predetermined score P_add2 for the scoring result P2 of the karaoke singing of the second song X2 to "5.0," and the predetermined score P_add3 for the scoring result P3 of the karaoke singing of the third song X3 to "2.5."

[0079] As a result, the scoring result is gradually adjusted and added over the predetermined number of songs until the user gradually recovers his / her rhythm, so that the scoring result can be corrected naturally, allowing the user to enjoy singing karaoke comfortably.

[0080] [Third embodiment] A karaoke device 1 according to a third embodiment of the present invention will be described below. In the description of the third embodiment, the same components as those in the first embodiment are given the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0081] In the karaoke device 1 of the third embodiment, as in the first embodiment, the control unit 10 executes a program stored in the storage unit 11 to operate as the evaluation unit 20, acquisition unit 21, identification unit 22, correction unit 23, and notification unit 24. In the third embodiment, the correction unit 23 is configured to add to the score the karaoke singing in a predetermined addition section of the singing section of the song. In this case, the correction unit 23 does not add to the score the karaoke singing in singing sections other than the addition section.

[0082] The song that the karaoke device 1 performs karaoke on is made up of multiple singing sections, and the evaluation unit 20 evaluates and scores the singing voice for each singing section of the song, and calculates the score for the karaoke singing based on the scoring results for all singing sections (for example, by calculating the average value). The song data stored in the storage unit 11 for each song includes singing section information for each singing section and performance section information for performance sections (non-sung sections) before and / or after each singing section. The karaoke device 1 pre-determines predetermined addition sections from the multiple singing sections of the song that will be added to the score.

[0083] For example, the singing section information may be set to the "verse verse of the first verse," "verse verse of the second verse," "chorus of the third verse," etc., or may be set more precisely, for example, to the "first half of the verse verse" every four bars. The performance section information may be set to the "introduction" before the "verse verse of the first verse," the "interlude" between the "chorus of the second verse" and the "verse verse of the third verse," the "postlude" after the "chorus of the third verse," etc.

[0084] [Evaluation Operation of the Third Embodiment] Next, in the third embodiment, an example of an evaluation operation by the karaoke device 1 to evaluate a karaoke singing performance when a user U sings karaoke of a piece of music X consisting of singing sections "S1" to "S9" after a predetermined blank period has elapsed will be described with reference to Fig. 6. Fig. 6 is a flowchart showing an example of the evaluation operation by the karaoke device 1 of the third embodiment.

[0085] In this example, it is assumed that user U logs in to the karaoke system 100 to which the karaoke device 1 belongs after "7 months + 4 days" have passed since the last karaoke performance. The acquisition unit 21 acquires user U's singing history from the storage unit 11 based on user U's user ID (step S301), and the identification unit 22 identifies the number of days D that have passed since user U's last karaoke performance to the current karaoke performance as "7 months + 4 days" based on user U's singing history (step S302).

[0086] When the user U reserves a song X using the remote control device 6, the control unit 10 of the karaoke main unit 2 registers the reserved song information of the song X in a reservation list in the storage unit 11. The control unit 10 also reads out the song data of the song X registered in the reservation list from the storage unit 11, and the sound source 12 and the audio input / output unit 13 perform karaoke performance of the song X (step S303).

[0087] Here, the song data for song X includes singing section information for each of the singing sections "S1," "S2," and "S3" (verse 1 to chorus), "S4," "S5," and "S6" (verse 2 to chorus), and "S7," "S8," and "S9" (verse 3 to chorus), and the singing sections "S1," "S2," and "S3" are set as predetermined addition sections. The sound source 12 and the audio input / output unit 13 perform karaoke performances of each singing section based on performance data corresponding to each singing section "S1" to "S9."

[0088] Furthermore, the evaluation unit 20 evaluates the karaoke singing by the user U for each singing section "S1" to "S9" of the song X, outputs scoring results "Q1" to "Q9" for each singing section "S1" to "S9," calculates the average of the scoring results "Q1" to "Q9," and outputs the scoring result P for the song X. The correction unit 23 corrects the scoring result Q of the addition section by adding a predetermined score P_add, and here, the result obtained by multiplying the original scoring result Q by a predetermined coefficient R_add (e.g., "0.60") is set as the predetermined score P_add to be added to the scoring result Q. An example of the scoring results "Q1" to "Q9" for each singing section "S1" to "S9" is shown in FIG. 7. In FIG. 7, n indicates the order of the singing sections, the singing sections are represented as "Sn," and the scoring results are represented as "Qn." The correction unit 23 adds points to the scoring result so that the scoring result after the addition is equal to or less than a predetermined upper limit of points to be added, for example, so that the scoring result after the addition is equal to or less than 95.0 points or less than 100 points.

[0089] Specifically, first, user U sings karaoke using microphone 3 along with the karaoke performance of singing section "S1" of song X, and then evaluation unit 20 evaluates user U's karaoke singing of singing section "S1" and outputs scoring result Q1 scoring "48.00" points (step S304).

[0090] Since the number of days D since user U's last karaoke performance, "7 months + 4 days," satisfies the predetermined elapsed condition of six months or more (step S305: YES), and the singing section "S1" satisfies the predetermined addition section (step S306: YES), the correction unit 23 multiplies the scoring result Q1 of user U's karaoke singing for the singing section "S1," "48.00," by the predetermined coefficient R_add "0.60," to obtain a predetermined score P_add1 "28.80," and adds this to the original scoring result Q1, correcting the scoring result Q1 to "48.00 + 28.80 = 76.80" points (step S307). After scoring the singing section "S1," unscored singing sections "S2" to "S9" remain (step S308: YES), so the correction unit 23 proceeds to scoring the next singing section, "S2" (step S304).

[0091] Next, the user U sings karaoke using the microphone 3 along with the karaoke performance of the singing section "S2" of the song X, and the evaluation unit 20 evaluates the karaoke singing of the singing section "S2" by the user U and outputs the scoring result Q2 scoring "54.00" points (step S304).

[0092] Since the number of days D since user U's last karaoke performance, "7 months + 4 days," satisfies the predetermined elapsed condition of six months or more (step S305: YES), and the singing section "S2" satisfies the predetermined addition section (step S306: YES), the correction unit 23 multiplies the scoring result Q2 of user U's karaoke singing for singing section "S2," "54.00," by the predetermined coefficient R_add "0.60," to obtain a predetermined score P_add2 of "32.40," and adds it to the original scoring result Q2, correcting the scoring result Q2 to "54.00 + 32.40 = 86.40" points (step S307). After scoring section "S2" is completed, unscored singing sections "S3" to "S9" remain (step S308: YES), so the correction unit 23 proceeds to scoring the next singing section, "S3" (step S304).

[0093] Next, the user U sings karaoke using the microphone 3 along with the karaoke performance of the singing section "S3" of the song X, and the evaluation unit 20 evaluates the karaoke singing of the singing section "S3" by the user U and outputs the scoring result Q3 scoring it as "56.00" points (step S304).

[0094] Since the number of days D since user U's last karaoke performance, "7 months + 4 days," satisfies the predetermined elapsed condition of six months or more (step S305: YES), and the singing section "S3" satisfies the predetermined addition section (step S306: YES), the correction unit 23 multiplies the scoring result Q3 of user U's karaoke singing for singing section "S3," "56.00," by the predetermined coefficient R_add "0.60," to obtain a predetermined score P_add3 "33.60," and adds this to the original scoring result Q3, correcting the scoring result Q3 to "56.00 + 33.60 = 89.60" points (step S307). After scoring section "S3" is completed, unscored singing sections "S4" to "S9" remain (step S308: YES), so the correction unit 23 proceeds to scoring the next singing section, "S4" (step S304).

[0095] Next, the user U sings karaoke using the microphone 3 along with the karaoke performance of the singing sections "S4," "S5," "S6," "S7," "S8," and "S9" of the song X, and the evaluation unit 20 evaluates the karaoke singing by the user U for the singing sections "S4," "S5," "S6," "S7," "S8," and "S9," and outputs the scoring results Q4 "72.00" points, Q5 "75.00" points, Q6 "78.00" points, Q7 "83.00" points, Q8 "86.00" points, and Q9 "88.00" points (step S304).

[0096] The correction unit 23 determines that the number of days D since the user U's last karaoke performance, "7 months + 4 days," satisfies the predetermined elapsed condition of six months or more (step S305: YES), but because the singing section "S4" to "S9" is not a predetermined addition section (step S306: NO), it does not make any addition correction to the scoring results Q4 to Q9 of the karaoke singing of the singing section "S4" to "S9" by the user U. After scoring the singing section "S9," there are no unscored singing sections remaining (step S308: NO), so it moves on to scoring the song X (step S309).

[0097] When the karaoke performance of song X is completed, the evaluation unit 20 calculates and outputs the score P of the karaoke singing of song X as "(76.80+86.40+89.60+72.00+75.00+78.00+83.00+86.00+88.0) / 9=81.64" points based on the corrected score results Q1 to Q3 of the karaoke singing of the singing sections "S1" to "S3" and the uncorrected score results Q4 to Q9 of the singing sections "S4" to "S9" (step S309).

[0098] The notification unit 24 notifies the user U of "81.64" points, which is the score P evaluated by the evaluation unit 20 for the user U's karaoke singing of the song X (step S310).

[0099] When a user starts singing karaoke after a long break, they may feel out of tune at the beginning of the song, but gradually regain their rhythm as the song progresses. According to the third embodiment, points are added to the scoring result during a predetermined addition period, which is the singing period until the user regains their rhythm. This prevents the scoring result from being negatively affected by the break, allowing the user to enjoy singing karaoke comfortably. Furthermore, after the user regains their rhythm after singing karaoke for the predetermined addition period, their karaoke singing is scored as usual, allowing the user to enjoy singing karaoke.

[0100] In the third embodiment, the correction unit 23 sets the predetermined coefficient R_add for the predetermined score P_add to "0.60" for the singing section, which is the predetermined addition section, but the present invention is not limited to this example. In another example, the correction unit 23 may set a different predetermined coefficient R_add for each singing section, which is the predetermined addition section, and in this case, the predetermined coefficient R_add may be set to a smaller value in the order of the karaoke performance. In other words, the earlier the karaoke performance is, the larger the predetermined coefficient R_add may be set.

[0101] For example, taking the singing section "S1" to "S3", which is the predetermined addition section of song X described in the evaluation operation of karaoke device 1 of the third embodiment above, as an example, correction unit 23 may correct the scoring result Q1 of the karaoke singing in singing section "S1" using a predetermined coefficient R_add1 of "0.60", correct the scoring result Q2 of the karaoke singing in singing section "S2" using a predetermined coefficient R_add2 of "0.40", and correct the scoring result Q3 of the karaoke singing in singing section "S3" using a predetermined coefficient R_add3 of "0.20".

[0102] Thus, during a predetermined addition period until the user gradually recovers his / her rhythm, the score is added while gradually adjusting the score result, so that the score result can be corrected naturally, allowing the user to enjoy singing karaoke comfortably.

[0103] [Fourth embodiment] A karaoke device 1 according to a fourth embodiment of the present invention will be described below. In the description of the fourth embodiment, the same components as those in the first embodiment are given the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0104] In the karaoke device 1 of the fourth embodiment, as in the first embodiment, the control unit 10 operates as an evaluation unit 20, an acquisition unit 21, an identification unit 22, a correction unit 23 and an alarm unit 24 by executing a program stored in the memory unit 11, and in the fourth embodiment in particular, the correction unit 23 is configured to add to the current scoring result based on a comparison between the user's past karaoke singing scoring history and the current karaoke singing scoring result.

[0105] In other words, in addition to determining whether or not the predetermined progress condition is met, the correction unit 23 also determines whether or not the scoring history of past karaoke singing of the song for which the evaluation unit 20 evaluates the karaoke singing (for example, the average value of past scoring results) and the scoring result of the current karaoke singing of that song meet predetermined decrease conditions, and adds points to the scoring result if both the predetermined progress condition and the predetermined decrease condition are met.

[0106] Here, the predetermined decrease condition is set to a decrease threshold value obtained by multiplying the score of the current karaoke singing performance by a predetermined decrease rate (e.g., 90.0%), calculated by multiplying the score history (e.g., average value) of past karaoke singing performances. The decrease rate is set to 90.0% when the deviation of the score results of past karaoke singing performances from the average value is considered to be 10.0%, but it may also be calculated by statistically processing the distribution of past score results for each song using other methods. If the score result of the current karaoke singing performance is less than the decrease threshold value, the predetermined decrease condition is satisfied and the correction unit 23 adds points to the score result.

[0107] In addition, the karaoke device 1 stores the song IDs of the songs performed by each user as the singing history of that user in the storage unit 11, and also stores the scoring results of the evaluation unit 20 on the karaoke singing of that song as a scoring history included in the singing history.

[0108] [Evaluation Operation of the Fourth Embodiment] Next, in the fourth embodiment, an example of an evaluation operation in which the karaoke device 1 evaluates the karaoke singing of a piece of music X performed by a user U after a predetermined blank period has elapsed will be described with reference to Fig. 8. Fig. 8 is a flowchart showing an example of the evaluation operation of the karaoke device 1 in the fourth embodiment.

[0109] In this example, it is assumed that user U sang song X using karaoke device 1 before the blank period, and that karaoke device 1 stored the scoring results of user U's karaoke singing of song X as part of the singing history in storage unit 11. It is assumed that user U then logs in to karaoke system 100 to which karaoke device 1 belongs after the blank period of "7 months + 4 days" has passed since the last time he sang karaoke.

[0110] The acquisition unit 21 acquires the singing history of the user U from the memory unit 11 based on the user U's user ID (step S401), and the identification unit 22 identifies the number of days D that have elapsed since the user U's last karaoke singing to the current karaoke singing as "7 months + 4 days" based on the user U's singing history (step S402).

[0111] When user U reserves song X using remote control device 6, control unit 10 in karaoke main unit 2 registers the reserved song information of song X in a reservation list in storage unit 11 (step S403). Correction unit 23 extracts the scoring history of user U's past karaoke singing of song X based on user U's singing history, and calculates the average score P_ave of those scores to "87.5" (step S404). Control unit 10 also reads out the song data of song X registered in the reservation list from storage unit 11, and song X is played as karaoke by sound source 12 and audio input / output unit 13 (step S405).

[0112] The user U sings karaoke using the microphone 3 along with the karaoke performance of the song X, and the evaluation unit 20 evaluates the karaoke singing of the song X by the user U and outputs the scoring result P scoring it as "72.5" points (step S406).

[0113] The correction unit 23 calculates the reduction threshold as "87.5 x 0.90 = 78.75" based on the average value P_ave of the scoring results, which is the scoring history of past karaoke singing of song X, of "87.5", and the predetermined reduction rate of "90.0%". Since the scoring result P of the current karaoke singing of song X, "72.5", is less than the reduction threshold "78.75", the correction unit 23 determines that the predetermined reduction condition is met.

[0114] Then, since the number of days D since user U's last karaoke performance, "7 months + 4 days", meets the specified elapsed condition of 6 months or more (step S407: YES), and also meets the specified decrease condition for the karaoke performance of song X1 as described above (step S408: YES), the correction unit 23 adds the specified score P_add "10.0" to the scoring result P of user U's current karaoke singing of song X, "72.5", and corrects the scoring result P to "72.5 + 10.0 = 82.5" (step S409).

[0115] The notification unit 24 notifies the user U of "82.5" points, which is the score P of the karaoke singing of the song X by the user U, evaluated by the evaluation unit 20 and corrected by the correction unit 23 (step S409).

[0116] For some users, even if they have had a long break from singing karaoke, their singing ability may not have deteriorated significantly compared to before the break, for example, by practicing karaoke at a home karaoke facility. Based on a comparison of the scoring history of past karaoke singing performances with the scoring result of the current karaoke performance, if the current scoring result is not poor, it can be determined that the user's singing ability has not deteriorated. Therefore, the user can enjoy singing karaoke comfortably without adding points to the scoring result. Note that, if the correction unit 23 determines that the user's singing ability has not deteriorated for a given song, it may not determine the number of days since the break or add the predetermined points for subsequent songs. Alternatively, it may determine the number of days since the break and add the predetermined points for each song.

[0117] On the other hand, based on the comparison of the scoring history of past karaoke singing with the scoring results of the current karaoke singing, if the current scoring results are poor, it can be determined that the singing ability has deteriorated or that the user's condition has not improved.Therefore, according to the fourth embodiment, by adding points to the scoring results, the scoring results will not deteriorate due to a gap in singing, and the user can enjoy singing karaoke comfortably.

[0118] In the above-described embodiments, the user's singing history is stored in the storage unit 11 of the karaoke machine 1, but the present invention is not limited to this example. In another example, the karaoke machine 1 may be communicably connected to the server device 7 of the karaoke system 100 via a predetermined network, and the singing history of each user may be stored in the server device 7. In this case, when the acquisition unit 21 of the karaoke machine 1 needs the user's singing history, it accesses the server device 7 and reads out the user's singing history.

[0119] Although the first to fourth embodiments have been described separately above, the karaoke machine 1 of the present invention may be configured by appropriately combining the functions of the first to fourth embodiments (including modifications). For example, the karaoke machine 1 may be configured by combining the second and third embodiments, so that karaoke singing in the addition section of only a predetermined number of songs in the order of karaoke performance is added to the score result.

[0120] Furthermore, the present invention can be modified as appropriate within the scope of the claims and the gist or idea of the invention that can be read from the entire specification, and karaoke devices with such modifications are also included in the technical idea of the present invention.
