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

[0026] "Example 1" The system of the present invention uses natural language processing technology as a means of accepting users' chatter and sympathy. Specifically, it takes in the user's utterance as text data and uses natural language processing technology to understand the content. This understanding includes semantic analysis of the utterance, sentiment analysis, topic analysis, etc. "Example 2" In addition, sensor data and input data from the user are used as a means of analyzing the user's situation, emotions, and vital signs. Specifically, vital data such as the user's heart rate, blood pressure, and body temperature are obtained from sensors, and by analyzing this data, the user's physical condition is understood. In addition, by analyzing speech data and text input data from the user, the user's emotional and thought states are understood. "Example 3" Furthermore, as a means of continuing to acknowledge and accept the user, the system generates appropriate responses according to the user's situation and emotions. Specifically, it uses natural language generation technology to generate responses based on the content of the user's speech, emotional state, vital data, etc. This response is one that acknowledges and accepts the user, and has the effect of reducing the user's feelings of loneliness and stress.

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

[0028] "Example 1" Step 1: Obtain speech from the user through an input device such as a microphone. Step 2: The acquired speech is converted into text data using speech recognition technology. Step 3: The converted text data is analyzed using natural language processing techniques, including semantic analysis of the utterance, sentiment analysis, and topic analysis. "Example 2" Step 1: Obtain the user's vital data from the sensor. The data includes heart rate, blood pressure, body temperature, etc. Step 2: Analyze the acquired vital data. This analysis allows the user's physical condition to be understood. Step 3: Analyze the user's speech data and text input data to understand the user's emotional and thought states. "Example 3" Step 1: Generate a response based on the user's spoken content, emotional state, vital data, etc. Natural language generation technology is used for this generation. Step 2: The generated response is communicated to the user using a means such as a text display or voice output. Step 3: Observe user reactions and adjust responses as needed, using machine learning techniques that use user reaction data as feedback.

[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 1" As one embodiment of the present invention, a system including an emotion engine is provided. This system estimates an emotional state from a user's speech and behavior. Specifically, the system analyzes the content of the user's speech, tone of voice, facial expressions, gestures, and the like, and estimates the user's emotional state from the results. For example, if a user says, "Today was fun," the system estimates from this speech that the user is feeling an emotion of joy. Also, if the user frowns or lowers the tone of his or her voice, the system estimates from these actions that the user is feeling an emotion of discomfort. "Example 2" In another embodiment of the present invention, a system is provided that adjusts a response to a user based on an estimated emotional state. Specifically, the system generates a response to the user taking into account the estimated emotional state. For example, if the system estimates that the user is feeling happy, the system generates a positive response such as "That's great!". If the system estimates that the user is feeling unpleasant, the system generates an empathetic response such as "That must have been hard." "Example 3" Further, as another embodiment of the present invention, a system is provided that learns the emotional state of a user and performs more accurate emotion estimation and response generation over time. Specifically, the system uses data obtained through interactions with the user as learning data to improve the accuracy of emotion estimation. For example, if a user smiles after uttering "Today was fun," the system learns the association between the utterance "Today was fun" and the emotion of joy. In this way, the system improves its ability to more accurately estimate the user's emotional state over time and generate appropriate responses.

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

[0032] "Example 1" Step 1: The emotion engine collects user utterances and actions. Step 2: Analyze the collected data and infer the user's emotional state. Step 3: The system records the estimated emotional state. "Example 2" Step 1: The system estimates the user's emotional state. Step 2: Based on the estimated emotional state, the system generates a response to the user. Step 3: Present the generated response to the user. "Example 3" Step 1: The system collects learning data obtained through interactions with users. Step 2: Using the collected training data, the system improves the accuracy of emotion estimation. Step 3: Using the improved accuracy of emotion estimation, the system generates an appropriate response.

[0033] The specific processing unit 290 transmits the result of the specific processing to the smart device 14. In the smart device 14, the control unit 46A causes the output device 40 to output the result of the specific processing. The microphone 38B acquires a voice indicating a user input for the result of the specific processing. The control unit 46A transmits the voice data indicating the user input acquired by the microphone 38B to the data processing device 12. In the data processing device 12, the specific processing unit 290 acquires the voice data.

[0034] 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.

"Example 3" Furthermore, as a means of continuing to acknowledge and accept the user, the system generates appropriate responses according to the user's situation and emotions. Specifically, it uses natural language generation technology to generate responses based on the content of the user's speech, emotional state, vital data, etc. This response is one that acknowledges and accepts the user, and has the effect of reducing the user's feelings of loneliness and stress.

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

[0074] "Example 1" Step 1: Obtain speech from the user through an input device such as a microphone. Step 2: The acquired speech is converted into text data using speech recognition technology. Step 3: The converted text data is analyzed using natural language processing techniques, including semantic analysis of the utterance, sentiment analysis, and topic analysis. "Example 2" Step 1: Obtain the user's vital data from the sensor. The data includes heart rate, blood pressure, body temperature, etc. Step 2: Analyze the acquired vital data. This analysis allows the user's physical condition to be understood. Step 3: Analyze the user's speech data and text input data to understand the user's emotional and thought states. "Example 3" Step 1: Generate a response based on the user's spoken content, emotional state, vital data, etc. Natural language generation technology is used for this generation. Step 2: The generated response is communicated to the user using a means such as a text display or voice output. Step 3: Observe user reactions and adjust responses as needed, using machine learning techniques that use user reaction data as feedback.

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

[0076] "Example 1" As one embodiment of the present invention, a system including an emotion engine is provided. This system estimates an emotional state from a user's speech and behavior. Specifically, the system analyzes the content of the user's speech, tone of voice, facial expressions, gestures, and the like, and estimates the user's emotional state from the results. For example, if a user says, "Today was fun," the system estimates from this speech that the user is feeling an emotion of joy. Also, if the user frowns or lowers the tone of his or her voice, the system estimates from these actions that the user is feeling an emotion of discomfort. "Example 2" In another embodiment of the present invention, a system is provided that adjusts a response to a user based on an estimated emotional state. Specifically, the system generates a response to the user taking into account the estimated emotional state. For example, if the system estimates that the user is feeling happy, the system generates a positive response such as "That's great!". If the system estimates that the user is feeling unpleasant, the system generates an empathetic response such as "That must have been hard." "Example 3" Further, as another embodiment of the present invention, a system is provided that learns the emotional state of a user and performs more accurate emotion estimation and response generation over time. Specifically, the system uses data obtained through interactions with the user as learning data to improve the accuracy of emotion estimation. For example, if a user smiles after uttering "Today was fun," the system learns the association between the utterance "Today was fun" and the emotion of joy. In this way, the system improves its ability to more accurately estimate the user's emotional state over time and generate appropriate responses.

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

[0078] "Example 1" Step 1: The emotion engine collects user utterances and actions. Step 2: Analyze the collected data and infer the user's emotional state. Step 3: The system records the estimated emotional state. "Example 2" Step 1: The system estimates the user's emotional state. Step 2: Based on the estimated emotional state, the system generates a response to the user. Step 3: Present the generated response to the user. "Example 3" Step 1: The system collects learning data obtained through interactions with users. Step 2: Using the collected training data, the system improves the accuracy of emotion estimation. Step 3: Using the improved accuracy of emotion estimation, the system generates an appropriate response.

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.

[0094] Next, the specific processing by the specific processing unit 290 of the data processing device 12 will be described.

[0095] "Example 1" The system of the present invention uses natural language processing technology as a means of accepting users' chatter and sympathy. Specifically, it takes in the user's utterance as text data and uses natural language processing technology to understand the content. This understanding includes semantic analysis of the utterance, sentiment analysis, topic analysis, etc. "Example 2" In addition, sensor data and input data from the user are used as a means of analyzing the user's situation, emotions, and vital signs. Specifically, vital data such as the user's heart rate, blood pressure, and body temperature are obtained from sensors, and by analyzing this data, the user's physical condition is understood.

[0098] In addition, an emotion engine that estimates the user's emotion may be further combined. That is, the identification processing unit 290 may estimate the user's emotion using the emotion identification model 59, and perform identification processing using the user's emotion.

[0099] "Example 1" As one embodiment of the present invention, a system including an emotion engine is provided. This system estimates an emotional state from a user's speech and behavior.

[0100] The process flow of each embodiment will be described below.

[0101] "Example 1" Step 1: The emotion engine collects user utterances and actions. Step 2: Analyze the collected data and infer the user's emotional state. Step 3: The system records the estimated emotional state. "Example 2" Step 1: The system estimates the user's emotional state.

[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.

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 3 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.

[0113] In the above embodiment, an example in which the specific processing program 56 is stored in the storage 32 has been described, but the technology of the present disclosure is not limited to this. For example, the specific processing program 56 may be stored in a portable computer-readable non-transitory storage medium such as a Universal Serial Bus (USB) memory. The specific processing program 56 stored in the non-transitory storage medium is installed in the computer 22 of the data processing device 12. The processor 28 executes the specific processing in accordance with the specific processing program 56.

[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.

[0118] As an example of a configuration using one processor, first, one processor is configured by combining one or more CPUs and software, and this processor functions as a hardware resource that executes a specific process. 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.

[0119] Furthermore, more specifically, the hardware structure of these various processors can be an electric circuit that combines circuit elements such as semiconductor elements.
