[0109] Next, a description will be given of Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the smart device 14 will be referred to as a "terminal."
[0110] Currently, voice communication relies on direct voice communication, which makes it difficult to use in quiet environments or places where privacy is required. Voice communication is also difficult for people with hearing impairments. Furthermore, conventional voice input systems have problems with misrecognition due to background noise and differences in speaking speed.

[0112] In this invention, the server includes means for capturing the user's lip and tongue movements, means for generating text based on the captured movements, means for converting the generated text into speech, means for transmitting the generated speech data to another terminal, and means for converting the speech data received from the other terminal into text. This enables silent calls, allowing for smooth and safe calls even in quiet environments or places where privacy is required. It also provides an alternative means of voice calls for people with hearing impairments, enabling highly accurate calls unaffected by background noise or speech rate.
[0113] "Capturing means" refers to devices and software that detect the user's lip and tongue movements in real time and acquire and store them as visual data.

[0115] The "means for converting to speech" refers to devices and software for converting the generated text data into synthetic speech. Specifically, speech synthesis technology is used.
[0116] The "transmitting means" refers to a device and software for transmitting the generated voice data to another terminal via a network.
[0117] The "means for converting into text" refers to the device and software that analyzes the voice data received from the other party's terminal and converts it into text data. Specifically, it uses voice recognition technology.
[0118] "Conversational context" refers to information and processing methods for generating appropriate text based on the context of the user's statements and the flow of the dialogue.
[0119] "Past learning data" refers to data accumulated based on the user's past training and conversation content, and is the data and processing method used to improve the accuracy of text generation.
[0120] The present invention relates to a "Silent Call" system that allows users to make calls without making any sound. This system provides the function of capturing the movements of the user's lips and tongue, generating text based on the captured movements, and converting the text into speech. It is also possible to convert the speech of the other party into text and provide it to the user.
[0121] System configuration
[0122] Capture Device
[0123] The user speaks silently, and the device uses the front camera to capture the user's lip and tongue movements in real time. The captured movements are saved as visual data. The front camera uses a high-resolution camera and a dedicated chip for real-time image processing.
[0124] Data transmission and analysis
[0125] The device sends the captured visual data to a server, where it is encrypted and transmitted securely using the HTTPS protocol.
[0126] The server analyzes the received visual data and generates corresponding text using CNN (Convolutional Neural Network) and RNN (Recurrent Neural Network) technologies, generating highly accurate text based on the user's past learning data and conversational context.
[0127] Text-to-speech
[0128] The server converts the generated text into audio data using TTS (Text to Speech) technology, such as Google Cloud Text-to-Speech. This audio data is generated as a high-quality audio file (e.g., WAV format).
[0129] The server transmits the generated voice data to the other terminal in real time.
[0130] Response processing from the other party
[0131] The other device captures the voice data spoken by the other user and sends it to the server. The voice data is encrypted and sent using the HTTPS protocol.
[0132] The server converts the received voice data into text using ASR (Automatic Speech Recognition) technology. In this case, we use "Google Cloud Speech-to-Text."
[0133] The server sends the converted text to the user terminal.
[0134] The device will then display the received text to the user or play it as audio.
[0135] Specific examples
[0136] 1. User training
[0137] The user silently reads the training sample sentence, "I am currently in Tokyo."
[0138] The device's in-camera captures lip and tongue movements and sends the visual data to a server.
[0139] The server analyzes the received data and saves the text "I am in Tokyo now" along with the corresponding visual data as training data.
[0140] 2. Actual call
[0141] The user starts a call and silently says, "The meeting starts at 3:00 PM."
[0142] The device's in-camera captures the user's lip and tongue movements and sends the visual data to a server.
[0143] The server analyzes the visual data and generates the text "The meeting starts at 3pm" based on the training data and context.
[0144] The server converts the text into voice and transmits the voice data to the other terminal.
[0145] The other device plays the received voice data and transmits the user's words to the other device.
[0146] 3. Response from the other person
[0147] The other person will respond by voice, "Understood, I'll join."
[0148] The remote terminal captures the voice data and sends it to the server.
[0149] The server converts the voice data into text and sends it to the user's device.
[0150] The device will then display the received text to the user or play it as audio.
[0151] This allows the system to provide a smooth and secure means of making calls even in quiet environments or where privacy is required. By utilizing past training data and conversation context, the system can generate text with higher accuracy and achieve natural-sounding voice calls.
[0152] Prompt Sentence Examples
[0153] Here are some example prompts to present to a generative AI model:

[0171] The server inputs the features into a recurrent neural network (RNN) model and generates the corresponding text, taking into account the user's past learning data and conversational context.
[0172] Input: Visual data (received data from the server)
[0173] Output: The generated text
[0174] Step 4: Text-to-speech

[0487] server:
[0488] The generated voice data is transmitted to another terminal in real time.
[0489] 4. Processing replies from the other party
[0490] Remote device:
[0491] As with a normal voice call, the voice data from the other party is captured and sent to the server.
[0492] server:
[0493] The received voice data is converted into text using voice recognition technology, and the text and emotional data are sent to the user's device.
[0494] Device:
[0495] It receives text and emotion data and displays it to the user. It also synthesizes the text into speech and plays it back with the emotion reflected.
[0496] Specific examples
[0497] 1. User training:
[0498] The user silently reads the training sample sentence, "I am in Tokyo now." The device captures lip and tongue movements with the front camera and sends the visual data to the server. It also captures facial expressions and sends them as emotional data. The server analyzes the received data and saves the visual and emotional data corresponding to the text "I am in Tokyo now" as training data.
[0499] 2. Actual call:
[0500] The user silently utters, "The meeting will start at 3 PM." The device captures lip and tongue movements with the in-camera and sends the visual data to the server. It also sends facial expression data for emotion recognition. The server analyzes the visual and emotional data and generates the text "The meeting will start at 3 PM" based on the learning data and context. It then converts this into speech using emotion-reflecting speech synthesis technology and sends it to the other device. The other device receives the voice data and conveys the user's remarks to the other party.
[0501] 3. Response from the other person:
[0502] The other party responds by saying "Got it. I'll join." The other party's device captures the voice data and sends it to the server. The server converts the voice data into text and sends the text and emotion data to the user's device. The device receives the text and emotion data and displays it to the user or plays it back as voice.
[0503] Example prompt for a generative AI model:
[0504] "Analyze the user's lip and tongue movements and generate text. Use the following video stream data. Also, recognize emotions from facial expressions and generate audio data that reflects them. Video stream data example: [Image data] Emotion data example: [Emotion label based on image data]"
[0505] The flow of the specific processing in the application example 2 will be described with reference to FIG.
[0506] Step 1:
[0507] The user silently speaks. For example, in a quiet environment, the user silently utters, "The meeting will start at 3:00 PM." At this time, the user moves their mouth in the same way as they would during a normal phone call.
[0508] Step 2:
[0509] The device uses an in-camera and specific sensors to capture the user's lip and tongue movements in real time. The video data captured by the in-camera is input, and visual data for analyzing lip and tongue movements is output. The device also captures the user's facial expressions. This facial expression data is also output as visual data.
[0510] Step 3:
[0511] The terminal transmits the captured visual data to the server. The input is the captured visual data, and the output is the data transmission to the server. Network communication technology is used for data transmission.
[0512] Step 4:
[0513] The server analyzes the received visual data. Specifically, it analyzes lip and tongue movement data and facial expression data to generate text data. The input is the received visual data, and the output is the text data generated by the data analysis process. LipMovementRecognizer and EmotionRecognizer are used for the analysis.
[0514] Step 5:
[0515] The server uses the conversational context and the user's past learning data to improve the accuracy of the generated text. The input is the initial text data, the user's past learning data, and the conversational context, and the output is the final text data with high accuracy. Natural language processing technology is used for data processing.
[0516] Step 6:

[0630] "Past learning data" refers to data accumulated based on the user's past training and conversation content, and is the data and processing method used to improve the accuracy of text generation.
[0631] The present invention relates to a "Silent Call" system that allows users to make calls without making any sound. This system provides the function of capturing the movements of the user's lips and tongue, generating text based on the captured movements, and converting the text into speech. It is also possible to convert the speech of the other party into text and provide it to the user.
[0632] System configuration

[0642] The other device captures the voice data spoken by the other user and sends it to the server. The voice data is encrypted and sent using the HTTPS protocol.
[0643] The server converts the received voice data into text using ASR (Automatic Speech Recognition) technology. In this case, we use "Google Cloud Speech-to-Text."
[0644] The server sends the converted text to the user terminal.
[0645] The device will then display the received text to the user or play it as audio.
[0646] Specific examples
[0647] 1. User training
[0648] The user silently reads the training sample sentence, "I am currently in Tokyo."
[0649] The device's in-camera captures lip and tongue movements and sends the visual data to a server.

[1019] Step 2:
[1020] The device uses an in-camera and specific sensors to capture the user's lip and tongue movements in real time. The video data captured by the in-camera is input, and visual data for analyzing lip and tongue movements is output. The device also captures the user's facial expressions. This facial expression data is also output as visual data.
[1021] Step 3:
[1022] The terminal transmits the captured visual data to the server. The input is the captured visual data, and the output is the data transmission to the server. Network communication technology is used for data transmission.
[1023] Step 4:
[1024] The server analyzes the received visual data. Specifically, it analyzes lip and tongue movement data and facial expression data to generate text data. The input is the received visual data, and the output is the text data generated by the data analysis process. LipMovementRecognizer and EmotionRecognizer are used for the analysis.
[1025] Step 5:

[1031] Step 8:
[1032] The other device plays back the received voice data and transmits the user's speech to the other device. The input is the received voice data, and the output is the played voice.
[1033] Step 9:
[1034] The other party responds with voice, just like in a normal voice call. For example, they might respond with, "Got it. I'll join." This voice is captured by the other party's device.
[1035] Step 10:
[1036] The remote terminal transmits the captured voice data to the server. The input is the voice data, and the output is the data transmission to the server.
[1037] Step 11:

[1141] "Past learning data" refers to data accumulated based on the user's past training and conversation content, and is the data and processing method used to improve the accuracy of text generation.
[1142] The present invention relates to a "Silent Call" system that allows users to make calls without making any sound. This system provides the function of capturing the movements of the user's lips and tongue, generating text based on the captured movements, and converting the text into speech. It is also possible to convert the speech of the other party into text and provide it to the user.
[1143] System configuration
[1144] Capture Device
[1145] The user speaks silently, and the device uses the front camera to capture the user's lip and tongue movements in real time. The captured movements are saved as visual data. The front camera uses a high-resolution camera and a dedicated chip for real-time image processing.

[1148] The server analyzes the received visual data and generates corresponding text using CNN (Convolutional Neural Network) and RNN (Recurrent Neural Network) technologies, generating highly accurate text based on the user's past learning data and conversational context.
[1149] Text-to-speech
[1150] The server converts the generated text into audio data using TTS (Text to Speech) technology, such as Google Cloud Text-to-Speech. This audio data is generated as a high-quality audio file (e.g., WAV format).
[1151] The server transmits the generated voice data to the other terminal in real time.
[1152] Response processing from the other party
[1153] The other device captures the voice data spoken by the other user and sends it to the server. The voice data is encrypted and sent using the HTTPS protocol.
[1154] The server converts the received voice data into text using ASR (Automatic Speech Recognition) technology. In this case, we use "Google Cloud Speech-to-Text."
[1155] The server sends the converted text to the user terminal.
[1156] The device will then display the received text to the user or play it as audio.
[1157] Specific examples
[1158] 1. User training
[1159] The user silently reads the training sample sentence, "I am currently in Tokyo."
[1160] The device's in-camera captures lip and tongue movements and sends the visual data to a server.

[1642] Example 1
[1643] Next, a description will be given of Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the robot 414 will be referred to as a "terminal."
[1644] Currently, voice communication relies on direct voice communication, which makes it difficult to use in quiet environments or places where privacy is required. Voice communication is also difficult for people with hearing impairments. Furthermore, conventional voice input systems have problems with misrecognition due to background noise and differences in speaking speed.
[1645] The specific processing by the specific processing unit 290 of the data processing device 12 in the first embodiment is realized by the following means.
[1646] In this invention, the server includes means for capturing the user's lip and tongue movements, means for generating text based on the captured movements, means for converting the generated text into speech, means for transmitting the generated speech data to another terminal, and means for converting the speech data received from the other terminal into text. This enables silent calls, allowing for smooth and safe calls even in quiet environments or places where privacy is required. It also provides an alternative means of voice calls for people with hearing impairments, enabling highly accurate calls unaffected by background noise or speech rate.
[1647] "Capturing means" refers to devices and software that detect the user's lip and tongue movements in real time and acquire and store them as visual data.

[1649] The "means for converting to speech" refers to devices and software for converting the generated text data into synthetic speech. Specifically, speech synthesis technology is used.
[1650] The "transmitting means" refers to a device and software for transmitting the generated voice data to another terminal via a network.
[1651] The "means for converting into text" refers to the device and software that analyzes the voice data received from the other party's terminal and converts it into text data. Specifically, it uses voice recognition technology.
[1652] "Conversational context" refers to information and processing methods for generating appropriate text based on the context of the user's statements and the flow of the dialogue.
[1653] "Past learning data" refers to data accumulated based on the user's past training and conversation content, and is the data and processing method used to improve the accuracy of text generation.
[1654] The present invention relates to a "Silent Call" system that allows users to make calls without making any sound. This system provides the function of capturing the movements of the user's lips and tongue, generating text based on the captured movements, and converting the text into speech. It is also possible to convert the speech of the other party into text and provide it to the user.
[1655] System configuration
[1656] Capture Device
[1657] The user speaks silently, and the device uses the front camera to capture the user's lip and tongue movements in real time. The captured movements are saved as visual data. The front camera uses a high-resolution camera and a dedicated chip for real-time image processing.
[1658] Data transmission and analysis
[1659] The device sends the captured visual data to a server, where it is encrypted and transmitted securely using the HTTPS protocol.
[1660] The server analyzes the received visual data and generates corresponding text using CNN (Convolutional Neural Network) and RNN (Recurrent Neural Network) technologies, generating highly accurate text based on the user's past learning data and conversational context.
[1661] Text-to-speech
[1662] The server converts the generated text into audio data using TTS (Text to Speech) technology, such as Google Cloud Text-to-Speech. This audio data is generated as a high-quality audio file (e.g., WAV format).
[1663] The server transmits the generated voice data to the other terminal in real time.
[1664] Response processing from the other party
[1665] The other device captures the voice data spoken by the other user and sends it to the server. The voice data is encrypted and sent using the HTTPS protocol.
[1666] The server converts the received voice data into text using ASR (Automatic Speech Recognition) technology. In this case, we use "Google Cloud Speech-to-Text."
[1667] The server sends the converted text to the user terminal.
[1668] The device will then display the received text to the user or play it as audio.
[1669] Specific examples
[1670] 1. User training
[1671] The user silently reads the training sample sentence, "I am currently in Tokyo."
[1672] The device's in-camera captures lip and tongue movements and sends the visual data to a server.

[1682] The remote terminal captures the voice data and sends it to the server.
[1683] The server converts the voice data into text and sends it to the user's device.
[1684] The device will then display the received text to the user or play it as audio.
[1685] This allows the system to provide a smooth and secure means of making calls even in quiet environments or where privacy is required. By utilizing past training data and conversation context, the system can generate text with higher accuracy and achieve natural-sounding voice calls.

[1996] (Application example 2)
[1997] Next, a description will be given of Application Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the robot 414 will be referred to as a "terminal."
[1998] In modern society, there is a growing demand for calls and communication in situations where confidentiality and privacy are essential. However, conventional voice calls pose the risk of sound leakage and eavesdropping, making them unsuitable for use in quiet environments or sensitive situations. There is also a need for a method to convey text information to the other party more accurately and emotionally. Technology is needed to solve this problem and enable emotionally charged, natural communication even in silent environments.
[1999] The specific processing by the specific processing unit 290 of the data processing device 12 in Application Example 2 is realized by the following means. In this invention, the server includes means for capturing the movements of the user's lips and tongue, means for generating text based on the captured movements, means for recognizing the user's emotions and reflecting them in the generated text, and means for converting the generated text into speech. This makes it possible to accurately generate text from the movements of the lips and tongue even in a silent environment, enabling voice calls that reflect the user's emotions.
[2000] "Means for capturing the movement of a user's lips and tongue" refers to devices or technologies that use an in-camera or specific sensors to capture the movement and shape of the area around a user's mouth in real time and record it as digital data.
[2001] "Means for generating text from captured movements" means algorithms and software for analyzing captured lip and tongue movement data and converting it into corresponding characters, words, or sentences.
[2002] "Means for recognizing user emotions and reflecting them in text generation" refers to technology that uses image analysis technology and facial expression recognition engines to detect emotions from the user's facial expressions and incorporate that emotional information into the text generation process.
[2003] "Means for converting generated text into speech" refers to software and hardware that utilizes speech synthesis technology using artificial intelligence to convert text data into speech data and generate natural-sounding speech that reflects emotion.
[2004] "Means for improving the accuracy of text generation by utilizing conversational context and the user's past learning data" refers to algorithms and databases that utilize the user's past conversation history and contextual information from dialogue to improve the content and accuracy of the generated text.
[2005] "Means for transmitting the generated voice data and emotional data to another terminal in real time and conversing with the other party" refers to communication technologies and protocols that enable real-time communication by quickly transmitting the generated voice data and emotional information to another device via a network.
[2006] The "Secure Silent Call System" that realizes this application example captures the movement of the user's lips and tongue, generates text based on that movement, recognizes the user's emotions and reflects them in the generated text, converts the generated text into speech, and transmits it to other devices in real time, enabling communication.
[2007] System configuration
[2008] 1. Capture device and emotion recognition engine
[2009] user:
[2010] This feature is intended for use in quiet environments such as conference rooms and libraries.

[2017] The software analyzes the received visual data and generates text based on lip and tongue movements and facial expressions, leveraging the user's past learning data and conversational context. The software includes a lip movement recognition engine (LipMovementRecognizer) and an emotion recognition engine (EmotionRecognizer).
[2018] 3. Text-to-speech

[2020] The generated text and emotion data are then converted into emotion-reflecting voice data using speech synthesis technology. This process is carried out using TextToSpeech software.
[2021] server:
[2022] The generated voice data is transmitted to another terminal in real time.
[2023] 4. Processing replies from the other party
[2024] Remote device:
[2025] As with a normal voice call, the voice data from the other party is captured and sent to the server.
[2026] server:
[2027] The received voice data is converted into text using voice recognition technology, and the text and emotional data are sent to the user's device.
[2028] Device:
[2029] It receives text and emotion data and displays it to the user. It also synthesizes the text into speech and plays it back with the emotion reflected.
[2030] Specific examples
[2031] 1. User training:
[2032] The user silently reads the training sample sentence, "I am in Tokyo now." The device captures lip and tongue movements with the front camera and sends the visual data to the server. It also captures facial expressions and sends them as emotional data. The server analyzes the received data and saves the visual and emotional data corresponding to the text "I am in Tokyo now" as training data.
[2033] 2. Actual call:
[2034] The user silently utters, "The meeting will start at 3 PM." The device captures lip and tongue movements with the in-camera and sends the visual data to the server. It also sends facial expression data for emotion recognition. The server analyzes the visual and emotional data and generates the text "The meeting will start at 3 PM" based on the learning data and context. It then converts this into speech using emotion-reflecting speech synthesis technology and sends it to the other device. The other device receives the voice data and conveys the user's remarks to the other party.
[2035] 3. Response from the other person:
[2036] The other party responds by saying "Got it. I'll join." The other party's device captures the voice data and sends it to the server. The server converts the voice data into text and sends the text and emotion data to the user's device. The device receives the text and emotion data and displays it to the user or plays it back as voice.
[2037] Example prompt for a generative AI model:
[2038] "Analyze the user's lip and tongue movements and generate text. Use the following video stream data. Also, recognize emotions from facial expressions and generate audio data that reflects them. Video stream data example: [Image data] Emotion data example: [Emotion label based on image data]"
[2039] The flow of the specific processing in the application example 2 will be described with reference to FIG.
[2040] Step 1:
[2041] The user silently speaks. For example, in a quiet environment, the user silently utters, "The meeting will start at 3:00 PM." At this time, the user moves their mouth in the same way as they would during a normal phone call.
[2042] Step 2:
[2043] The device uses an in-camera and specific sensors to capture the user's lip and tongue movements in real time. The video data captured by the in-camera is input, and visual data for analyzing lip and tongue movements is output. The device also captures the user's facial expressions. This facial expression data is also output as visual data.
[2044] Step 3:
[2045] The terminal transmits the captured visual data to the server. The input is the captured visual data, and the output is the data transmission to the server. Network communication technology is used for data transmission.
[2046] Step 4:
[2047] The server analyzes the received visual data. Specifically, it analyzes lip and tongue movement data and facial expression data to generate text data. The input is the received visual data, and the output is the text data generated by the data analysis process. LipMovementRecognizer and EmotionRecognizer are used for the analysis.
[2048] Step 5:
[2049] The server uses the conversational context and the user's past learning data to improve the accuracy of the generated text. The input is the initial text data, the user's past learning data, and the conversational context, and the output is the final text data with high accuracy. Natural language processing technology is used for data processing.
[2050] Step 6:
[2051] The server converts the final text data and emotion data into speech. The input is the final text data and emotion data, and the output is speech data that reflects the emotion expression. TextToSpeech software is used for speech synthesis.
[2052] Step 7:
[2053] The server transmits the generated voice data to the remote terminal in real time. The input is voice data, and the output is voice data transmitted over the network. A communication protocol is used for transmission.
[2054] Step 8:
[2055] The other device plays back the received voice data and transmits the user's speech to the other device. The input is the received voice data, and the output is the played voice.
[2056] Step 9:
[2057] The other party responds with voice, just like in a normal voice call. For example, they might respond with, "Got it. I'll join." This voice is captured by the other party's device.
[2058] Step 10:
[2059] The remote terminal transmits the captured voice data to the server. The input is the voice data, and the output is the data transmission to the server.
[2060] Step 11:
[2061] The server analyzes the received voice data and converts it into text data. The input is voice data and the output is text data. The analysis is performed using voice recognition technology.
[2062] Step 12:
[2063] The server sends the generated text data and emotion data to the user terminal. The input is the text data and emotion data, and the output is the data transmission to the user terminal.
[2064] Step 13:
[2065] The terminal displays the received text data and emotion data to the user, and also plays the text as speech that reflects the emotion. The input is the text data and emotion data, and the output is the displayed text and the played speech.
[2066] 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 voice indicating a user input regarding 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.
[2067] 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> ), Gemini (Internet search <url: https: gemini.google.com ?hl="ja">) and other generation AIs. The data generation model 58 is obtained by performing deep learning on a neural network. A prompt including an instruction is input to the data generation model 58, and inference data such as voice data indicating voice, text data indicating text, and image data indicating an image is also input. The data generation model 58 performs inference on the input inference data in accordance with 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.
[2068] In the above embodiment, an example was given in which the specific processing is performed by the data processing device 12, but the technology of the present disclosure is not limited to this, and the specific processing may be performed by the robot 414.
[2069] The emotion identification model 59 as an emotion engine may determine the user's emotion according to a specific mapping. Specifically, the emotion identification model 59 may determine the user's emotion according to an emotion map (see FIG. 9), which is a specific mapping. Similarly, the emotion identification model 59 may determine the robot's emotion, and the identification processing unit 290 may perform identification processing using the robot's emotion.
[2070] FIG. 9 is a diagram illustrating 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. Emotions closer to the center of the concentric circles are more primitive. Emotions representing states and actions arising from a state of mind are arranged on the outer edges of the concentric circles. The concept of emotion includes both affect and mental states. Emotions generally generated from reactions occurring in the brain are arranged on the left side of the concentric circles. Emotions generally induced by situational judgment are arranged on the right side of the concentric circles. Emotions generally generated from reactions occurring in the brain and induced by situational judgment are arranged on the upper and lower sides of the concentric circles. Furthermore, the emotion of "pleasure" is arranged on the upper side of the concentric circles, and the emotion of "discomfort" is arranged on the lower side. In this way, in the emotion map 400, multiple emotions are mapped based on the structure by which emotions are generated, and emotions that tend to occur simultaneously are mapped close to each other.
[2071] These emotions are distributed in the 3 o'clock direction on emotion map 400, and typically 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.
[2072] The inside of emotion map 400 represents what is going on in the mind, and the outside of emotion map 400 represents behavior, so the further you go outside emotion map 400, the more visible the emotions become (the more they are expressed in behavior).
[2073] Human emotions are based on various balances, such as posture and blood sugar levels. When these balances deviate from the ideal, a state of discomfort is indicated, and when they approach the ideal, a state of pleasure is indicated. Emotions can also be created for robots, automobiles, and motorcycles, based on various balances, such as posture and remaining battery life. When these balances deviate from the ideal, a state of discomfort is indicated, and when they approach the ideal, a state of pleasure is indicated. An emotion map can be generated, for example, based on Dr. Mitsuyoshi's emotion map (Research on Voice Emotion Recognition and Emotional Brain Physiological Signal Analysis Systems, Tokushima University, Doctoral Dissertation: https: / / ci.nii.ac.jp / naid / 500000375379). The left half of the emotion map lists emotions belonging to the "reaction" domain, where sensation is dominant. The right half of the emotion map lists emotions belonging to the "situation" domain, where situational awareness is dominant.
[2074] The emotion map defines two emotions that promote learning. One is a negative emotion on the situation side, around the middle of "repentance" or "reflection." In other words, this occurs 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 a positive emotion on the response side, around "desire." In other words, this occurs when the robot experiences positive feelings such as "I want more" or "I want to know more."
[2075] The emotion identification model 59 inputs user input into a pre-trained neural network, obtains emotion values indicating each emotion shown in the emotion map 400, and determines the user's emotion. This neural network is pre-trained based on multiple pieces of training data that are combinations of 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, "relieved," "calm," and "reassuring," have similar emotion values.
[2076] The system according to the present disclosure has been described above mainly with respect to the functions of the data processing device 12, but the system according to the present disclosure is not necessarily implemented on a server.

[2080] 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.
