Voice Input Device Multi-User History Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current speech recognition services struggle to determine user intent and parameters when information associated with another user is required, limiting their ability to provide accurate responses based on utterance history.
Innovation Solution
A system that includes a server and electronic device configured to receive and analyze user utterances, identify speakers, and generate response messages by referencing utterance history of associated users, allowing for improved speech recognition services by incorporating information from multiple users' histories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speech recognition service uses only information associated with the current user, then user privacy is protected, but the service cannot determine intent and parameters when information from another user is required
Solution Approach 1:
The system segments user information access by creating separate utterance histories for different users while introducing a relationship management module that selectively connects related users. This allows the system to access another user's utterance history only when relationship information indicates permission, resolving the contradiction between maintaining user-specific data isolation and enabling controlled multi-user information access for improved intent determination.
2Measurement precision
If speech recognition service accesses utterance history of multiple users, then intent and parameters can be determined more accurately, but system complexity increases
Solution Approach 1:
The relationship management module serves as an intermediary between the speech recognition service and multi-user utterance histories. It manages the complexity of accessing and filtering information from multiple users by maintaining relationship data and controlling which users' histories can be accessed, thereby enabling precise speech recognition without directly managing the complexity of multi-user information access.
3Reliability
If speech recognition service references another user's utterance history, then service accuracy improves, but information security requirements increase
Solution Approach 1:
The system performs preliminary action by establishing user relationships and access permissions before accessing another user's utterance history. The relationship management module pre-configures which users are related and under what conditions their histories can be accessed, ensuring information security is maintained while enabling accurate response generation that leverages multi-user context when appropriate.
Data Source
AI summary
An electronic device according to an embodiment comprises a microphone, a communication circuitry, a memory storing utterance pattern information of a first user registered in the electronic device and instructions, and a processor connected to the microphone, the communication circuitry, and the memory. The instructions, when executed by the processor, cause the electronic device to: obtain a utterance through the microphone; determine whether the utterance is uttered by the first user based on the utterance pattern information; based on being determined the utterance is uttered by the first user, transmit the utterance to an external server through the communication circuitry; receive a response message corresponding to the utterance from the external server through the communication circuitry; and execute at least one function corresponding to the response message. The response message is generated with reference to utterance history of a second user different from the first user.
