[0025] Next, the specific processing by the specific processing unit 290 of the data processing device 12 will be described.

[0026] "Example 1" As one embodiment of the present invention, a GUI (Graphical User Interface) is provided as a means for inputting an artist name and song title specified by the user. This GUI includes text boxes for inputting the artist name and song title, and a button for confirming the input. For example, the user inputs "The Beatles" in the artist name text box and "Yesterday" in the song title text box, and presses a button to start generating a music track for the specified artist and song. "Example 2" The voice synthesis technology is used as a means of generating voice data of the specified artist. Specifically, past voice data of the specified artist is obtained from a database, and the voice data is analyzed to extract the voice characteristics of the artist. New voice data is generated based on the extracted voice characteristics. This voice data reproduces a voice that sounds as if the specified artist is singing. "Example 3" Music generation technology is used as a means of generating music data based on a specified song title. Specifically, existing music data related to the specified song title is retrieved from a database, and the music data is analyzed to extract the musical characteristics of the song. New music data is generated based on the extracted musical characteristics. This music data reproduces music as if the specified song was being played. "Example 4" The generated voice data and music data are combined to generate a single music track using voice and music mixing technology. Specifically, the generated voice data and music data are synchronized and mixed in an appropriate balance. This generates a single music track that sounds as if a specified artist is singing a specified song.

[0027] The process flow of each embodiment will be described below.

[0028] "Example 1" Step 1: The user enters an artist name and a song title. Specifically, the user enters "The Beatles" as the artist name and "Yesterday" as the song title in the text boxes on the GUI. Step 2: The user presses a button to confirm the input, and the system starts generating a music track for the specified artist and song. "Example 2" Step 1: The system retrieves the specified artist's past audio data from the database. Step 2: Analyze the acquired audio data and extract the artist's audio characteristics. Step 3: Based on the extracted voice features, new voice data is generated, which reproduces the voice as if it were being sung by the specified artist. "Example 3" Step 1: The system retrieves existing music data related to the specified song title from the database. Step 2: Analyze the acquired music data and extract the musical features of the song. Step 3: Based on the extracted musical features, new music data is generated, which reproduces music as if the specified song were being played. "Example 4" Step 1: Synchronize the generated voice data with the music data. Step 2: Mix the synchronized voice and music data in the right balance. Step 3: Output the mixed result as a single music track, which will generate a single music track as if the specified artist was singing the specified song.

[0029] Furthermore, an emotion engine that estimates the emotion of the user may be combined. That is, the identification processing unit 290 may estimate the emotion of the user using the emotion identification model 59, and perform identification processing using the emotion of the user.

[0030] "Example 5" The embodiment of the invention combining the emotion engine recognizes the emotion of the user and adjusts the generation of music data and voice data based on the emotion. Specifically, information such as the operation pattern, usage time, and frequency of use when the user uses the application is collected, and the emotional state of the user is estimated from this information. For example, if a user frequently uses the application, it is estimated that the user is enjoying himself / herself. Based on such an emotional state, the generation of music data and voice data is adjusted. For example, if it is estimated that the user is enjoying himself / herself, up-tempo songs and voice data with bright tones are generated. "Example 6" The emotion engine can also fine-tune the generation of music and voice data according to the user's emotions. For example, if the user is estimated to be depressed, it can generate soft-toned voice data and slow-tempo music. This allows the user to have a music experience that suits their emotional state. "Example 7" Furthermore, the emotion engine can track the user's emotional state over time. This allows the generation of music data and voice data that correspond to changes in the user's emotions. For example, if a user is excited when they first use the application, but becomes calmer over time, the emotion engine will generate up-tempo music at first, and generate softer voice data and slower songs over time. "Example 8" The emotion engine can also provide feedback to the user, as well as adjust the generation of music and voice data based on the user's emotional state. For example, if the user is estimated to be stressed, the emotion engine can generate relaxing music and suggest activities that will have a relaxing effect to the user. This allows the user to learn to control their emotions through music.

[0031] The process flow of each embodiment will be described below.

[0032] "Example 5" Step 1: The user starts the application. Step 2: The application collects information such as user operation patterns, usage time, and frequency of use. Step 3: The emotion engine infers the user's emotional state from the collected information. Step 4: Adjust the generation of music and speech data based on the estimated emotional state. "Example 6" Step 1: The user starts the application. Step 2: The application collects information such as user operation patterns, usage time, and frequency of use. Step 3: The emotion engine infers the user's emotional state from the collected information. Step 4: Fine-tune the generation of music and speech data based on the estimated emotional state. "Example 7" Step 1: The user starts the application. Step 2: The application collects information such as user operation patterns, usage time, and frequency of use. Step 3: The emotion engine infers the user's emotional state from the collected information. Step 4: The emotion engine tracks the user's emotional state over time and generates music and voice data that responds to those changes. "Example 8" Step 1: The user starts the application.

The communication I / Fs 44 and 26 are responsible for transmitting and receiving various types of information between the processor 46 and the processor 28 via the network 54. The transmission and reception of various types of information between the processor 46 and the processor 28 using the communication I / Fs 44 and 26 is performed in a secure state.

[0067] Fig. 6 shows an example of main functions of the data processing device 12 and the headset type terminal 314. As shown in Fig. 6, in the data processing device 12, a specific process is performed by the processor 28. A specific process program 56 is stored in the storage 32.

[0068] The specific processing program 56 is an example of a "program" according to the technology of the present disclosure. The processor 28 reads the specific processing program 56 from the storage 32, and executes the read specific processing program 56 on the RAM 30.

[0071] Next, the specific processing by the specific processing unit 290 of the data processing device 12 will be described.

[0072] "Example 1" As one embodiment of the present invention, a GUI (Graphical User Interface) is provided as a means for inputting an artist name and song title specified by the user. This GUI includes text boxes for inputting the artist name and song title, and a button for confirming the input. For example, the user inputs "The Beatles" in the artist name text box and "Yesterday" in the song title text box, and presses a button to start generating a music track for the specified artist and song. "Example 2" The voice synthesis technology is used as a means of generating voice data of the specified artist. Specifically, past voice data of the specified artist is obtained from a database, and the voice data is analyzed to extract the voice characteristics of the artist. New voice data is generated based on the extracted voice characteristics. This voice data reproduces a voice that sounds as if the specified artist is singing. "Example 3" Music generation technology is used as a means of generating music data based on a specified song title. Specifically, existing music data related to the specified song title is retrieved from a database, and the music data is analyzed to extract the musical characteristics of the song. New music data is generated based on the extracted musical characteristics. This music data reproduces music as if the specified song was being played. "Example 4" The generated voice data and music data are combined to generate a single music track using voice and music mixing technology. Specifically, the generated voice data and music data are synchronized and mixed in an appropriate balance. This generates a single music track that sounds as if a specified artist is singing a specified song.

[0073] The process flow of each embodiment will be described below.

[0074] "Example 1" Step 1: The user enters an artist name and a song title. Specifically, the user enters "The Beatles" as the artist name and "Yesterday" as the song title in the text boxes on the GUI. Step 2: The user presses a button to confirm the input, and the system starts generating a music track for the specified artist and song. "Example 2" Step 1: The system retrieves the specified artist's past audio data from the database. Step 2: Analyze the acquired audio data and extract the artist's audio characteristics. Step 3: Based on the extracted voice features, new voice data is generated, which reproduces the voice as if it were being sung by the specified artist. "Example 3" Step 1: The system retrieves existing music data related to the specified song title from the database. Step 2: Analyze the acquired music data and extract the musical features of the song. Step 3: Based on the extracted musical features, new music data is generated, which reproduces music as if the specified song were being played. "Example 4" Step 1: Synchronize the generated voice data with the music data. Step 2: Mix the synchronized voice and music data in the right balance. Step 3: Output the mixed result as a single music track, which will generate a single music track as if the specified artist was singing the specified song.

[0075] In addition, an emotion engine that estimates the emotion of the user may be further combined. That is, the identification processing unit 290 may estimate the emotion of the user using the emotion identification model 59, and perform identification processing using the emotion of the user.

[0076] "Example 5" The embodiment of the invention combining the emotion engine recognizes the emotion of the user and adjusts the generation of music data and voice data based on the emotion. Specifically, information such as the operation pattern, usage time, and frequency of use when the user uses the application is collected, and the emotional state of the user is estimated from this information. For example, if a user frequently uses the application, it is estimated that the user is enjoying himself / herself. Based on such an emotional state, the generation of music data and voice data is adjusted. For example, if it is estimated that the user is enjoying himself / herself, up-tempo songs and voice data with bright tones are generated. "Example 6" The emotion engine can also fine-tune the generation of music and voice data according to the user's emotions. For example, if the user is estimated to be depressed, it can generate soft-toned voice data and slow-tempo music. This allows the user to have a music experience that suits their emotional state. "Example 7" Furthermore, the emotion engine can track the user's emotional state over time. This allows the generation of music data and voice data that correspond to changes in the user's emotions. For example, if a user is excited when they first use the application, but becomes calmer over time, the emotion engine will generate up-tempo music at first, and generate softer voice data and slower songs over time. "Example 8" The emotion engine can also provide feedback to the user, as well as adjust the generation of music and voice data based on the user's emotional state. For example, if the user is estimated to be stressed, the emotion engine can generate relaxing music and suggest activities that will have a relaxing effect to the user. This allows the user to learn to control their emotions through music.

[0077] The process flow of each embodiment will be described below.

[0078] "Example 5" Step 1: The user starts the application. Step 2: The application collects information such as user operation patterns, usage time, and frequency of use. Step 3: The emotion engine infers the user's emotional state from the collected information. Step 4: Adjust the generation of music and speech data based on the estimated emotional state. "Example 6" Step 1: The user starts the application. Step 2: The application collects information such as user operation patterns, usage time, and frequency of use. Step 3: The emotion engine infers the user's emotional state from the collected information. Step 4: Fine-tune the generation of music and speech data based on the estimated emotional state. "Example 7" Step 1: The user starts the application. Step 2: The application collects information such as user operation patterns, usage time, and frequency of use. Step 3: The emotion engine infers the user's emotional state from the collected information. Step 4: The emotion engine tracks the user's emotional state over time and generates music and voice data that responds to those changes. "Example 8" Step 1: The user starts the application. Step 2: The application collects information such as user operation patterns, usage time, and frequency of use. Step 3: The emotion engine infers the user's emotional state from the collected information. Step 4: The emotion engine coordinates the generation of music and voice data and also provides feedback to the user.

[0079] The specific processing unit 290 transmits the result of the specific processing to the headset type terminal 314. In the headset type terminal 314, the control unit 46A causes the speaker 240 and the display 343 to output the result of the specific processing. The microphone 238 acquires voice indicating a user input for the result of the specific processing. The control unit 46A transmits voice data indicating the user input acquired by the microphone 238 to the data processing device 12. In the data processing device 12, the specific processing unit 290 acquires the voice data.

[0080] The data generation model 58 is a so-called generative AI (Artificial Intelligence). An example of the data generation model 58 is ChatGPT (Internet search<URL: https: / / openai.com / blog / chatgpt> ) and other generation AIs. The data generation model 58 is obtained by making a neural network perform deep learning. A prompt including an instruction is input to the data generation model 58, and inference data such as voice data indicating a voice, text data indicating a text, and image data indicating an image is input. The data generation model 58 performs inference on the input inference data according to the instruction indicated by the prompt, and outputs the inference result in a data format such as voice data and text data. Here, inference refers to, for example, analysis, classification, prediction, and / or summarization.

[0102] The specific processing unit 290 transmits the result of the specific processing to the robot 414. In the robot 414, the control unit 46A causes the speaker 240 and the control target 443 to output the result of the specific processing. The microphone 238 acquires a voice indicating a user input for the result of the specific processing.

In the data processing device 12, the specific processing unit 290 acquires the voice data.

[0103] The data generation model 58 is a so-called generative AI (Artificial Intelligence). An example of the data generation model 58 is ChatGPT (Internet search<URL: https: / / openai.com / blog / chatgpt> ) and other generation AIs. The data generation model 58 is obtained by making a neural network perform deep learning. A prompt including an instruction is input to the data generation model 58, and inference data such as voice data indicating a voice, text data indicating a text, and image data indicating an image is input. The data generation model 58 performs inference on the input inference data according to the instruction indicated by the prompt, and outputs the inference result in a data format such as voice data and text data. Here, inference refers to, for example, analysis, classification, prediction, and / or summarization.

[0104] In the above embodiment, an example was given in which the specific process was performed by the data processing device 12, but the technology of the present disclosure is not limited to this, and the specific process may be performed by the robot 414.

[0105] The emotion identification model 59 as an emotion engine may determine the emotion of the user according to a specific mapping. Specifically, the emotion identification model 59 may determine the emotion of the user according to an emotion map (see FIG. 9), which is a specific mapping. Similarly, the emotion identification model 59 may determine the emotion of the robot, and the identification processing unit 290 may perform identification processing using the emotion of the robot.

[0106] FIG. 9 is a diagram showing an emotion map 400 on which multiple emotions are mapped. In the emotion map 400, emotions are arranged in concentric circles radiating from the center. The closer to the center of the concentric circles, the more primitive emotions are arranged. The more outside the concentric circles, the more emotions that represent states and actions that arise from a state of mind are arranged. Emotions are a concept that includes emotions and mental states. On the left side of the concentric circles, emotions that are generally generated from reactions that occur in the brain are arranged. On the right side of the concentric circles, emotions that are generally induced by situational judgment are arranged. On the upper and lower sides of the concentric circles, emotions that are generally generated from reactions that occur in the brain and are induced by situational judgment are arranged. In addition, on the upper side of the concentric circles, emotions of "pleasure" are arranged, and on the lower side, emotions of "discomfort" are arranged. In this way, in the emotion map 400, multiple emotions are mapped based on the structure in which emotions are generated, and emotions that tend to occur simultaneously are mapped close to each other.

[0107] These emotions are distributed in the three o'clock direction of emotion map 400 and usually fluctuate between relief and anxiety. In the right half of emotion map 400, situational awareness dominates over internal sensations, resulting in a sense of calm.

[0108] The inside of emotion map 400 represents what is going on inside one's mind, and the outside of emotion map 400 represents behavior, so the further out you go on emotion map 400, the more visible the emotions become (the more they are expressed in behavior).

[0109] Here, human emotions are based on various balances such as posture and blood sugar level, and when these balances are far from the ideal, it indicates an unpleasant state, and when they are close to the ideal, it indicates a pleasant state. Emotions can also be created for robots, cars, motorcycles, etc., based on various balances such as posture and battery level, so that when these balances are far from the ideal, it indicates an unpleasant state, and when they are close to the ideal, it indicates a pleasant state. The emotion map may be generated, for example, based on the emotion map of Dr. Mitsuyoshi (Research on speech emotion recognition and emotion brain physiological signal analysis system, Tokushima University, doctoral dissertation: https: / / ci.nii.ac.jp / naid / 500000375379). On the left half of the emotion map, emotions belonging to an area called "reaction" where sensation is dominant are lined up. On the right half of the emotion map, emotions belonging to an area called "situation" where situation recognition is dominant are lined up.

[0110] The emotion map defines two emotions that promote learning. The first is the negative emotion around the middle of "repentance" or "remorse" on the situation side. In other words, this is when the robot experiences negative emotions such as "I never want to feel this way again" or "I don't want to be scolded again." The other is the positive emotion around "desire" on the response side. In other words, this is when the robot has positive feelings such as "I want more" or "I want to know more."

[0111] The emotion identification model 59 inputs the user input to a pre-trained neural network, obtains emotion values ​​indicating each emotion shown in the emotion map 400, and determines the emotion of the user. This neural network is pre-trained based on multiple learning data that are combinations of the user input and emotion values ​​indicating each emotion shown in the emotion map 400. Furthermore, this neural network is trained so that emotions that are located close to each other have similar values, as in the emotion map 900 shown in Fig. 10. Fig. 10 shows an example in which multiple emotions, "relief," "calm," and "encouraging," have similar emotion values.

[0112] In the above embodiment, an example was given in which a specific process is performed by one computer 22, but the technology disclosed herein is not limited to this, and distributed processing of the specific process may be performed by multiple computers, including computer 22.

[0114] In addition, the specific processing program 56 may be stored in a storage device such as a server connected to the data processing device 12 via the network 54, and the specific processing program 56 may be downloaded and installed on the computer 22 upon request from the data processing device 12.

[0115] It is not necessary to store all of the specific processing program 56 in a storage device such as a server connected to the data processing device 12 via the network 54, or to store all of the specific processing program 56 in the storage 32; only a portion of the specific processing program 56 may be stored.

Each processor has a built-in or connected memory, and each processor executes the specific process by using the memory.

[0117] The hardware resource that executes the specific process may be one of these various processors, or may be a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Also, the hardware resource that executes the specific process may be a single processor.

Second, there is a configuration using a processor that realizes the functions of the entire system including multiple hardware resources that execute a specific process on a single IC chip, as typified by SoC (System-on-a-chip). In this way, a specific process is realized using one or more of the above-mentioned various processors as hardware resources.
