System

A system comprising:

• circuitry configured to:
• receive, via a communication interface coupled to a packet-switched network, dialog data from a terminal device, apply a speech recognition model to audio signal data and a prosody analysis model to extract prosodic features, and generate text data and a prosodic feature set;
• analyze the text data using natural language processing to classify a request type and extract intention attributes, apply an emotion classification model to the text data and the prosodic feature set to generate an emotional state representation with confidence scores, and store the request type, intention attributes, and emotional state representation as profile data in a storage device;
• analyze the profile data to identify intention categories, preference patterns, regret patterns, and current concerns, construct a prompt sentence incorporating the identified profile attributes, and input the prompt sentence to a generative AI model to obtain a personalized message or proposal;
• transmit the personalized message or proposal to a terminal device associated with a target user via the communication interface, and adjust a response content to the user based on the emotional state representation;
• and
• acquire schedule information or environment information from at least one of a schedule management service and an information-providing service via the communication interface based on the request type.

A method comprising:

• receiving, via a communication interface coupled to a packet-switched network, dialog data from a terminal device as an audio signal or a character string, and generating text data by performing a speech recognition process on the audio signal or a character-string acquisition process on the character string;
• analyzing the text data by performing natural language processing to interpret a request and an intention of the user, classifying and recognizing an emotional state of the user from the text data, and associating the request, the intention, and the emotional state as attribute information of the user for storage as profile data in a storage device;
• determining, based on an analysis result, a type of access to an external information source, acquiring environment information or schedule information from at least one of an information-providing service and a schedule management service via the communication interface, and integrating and managing the acquired information in the storage device;
• creating, based on the profile data, a prompt sentence for instructing a generative AI model to generate a message or a proposal for a target user, and inputting the prompt sentence to the generative AI model to obtain generated content;
• and
• transmitting the generated content to a terminal device associated with the target user via the communication interface, and adjusting a response presented to the user on the basis of the recognized emotional state.
