Voiceprint-Based Response Tone Personalization in Voice Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice interaction systems lack personalization, responding to users in a uniform manner regardless of individual differences, leading to a non-specific dialog experience.
Innovation Solution
The system utilizes voiceprint features to tailor responses based on personal information associated with a user's voiceprint, enabling personalized interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed wake-up word is used for voice interaction, then the device can be activated reliably, but the response tone is uniform and lacks personalization for different users
Solution Approach 1:
The system performs voiceprint recognition and personal information retrieval in advance before generating the response tone. The electronic device pre-processes user identification and stores personal information including preferred tones, so that when a user interacts, the appropriate tone is already prepared and can be applied immediately without adding noticeable delay to the interaction flow.
2Adaptability or versatility
If voiceprint recognition is performed for each interaction, then personalized response tones can be provided, but the interaction time is increased
Solution Approach 1:
Voiceprint recognition is performed during device activation or login phases in advance. The system stores the recognized voiceprint and associated personal information in memory before actual voice interactions occur. This preliminary processing eliminates the need to perform voiceprint recognition during every interaction, significantly reducing interaction time while maintaining personalization capability.
Solution Approach 2:
Instead of performing full voiceprint recognition during each interaction, the system creates and stores a copy of the voiceprint template during preliminary phases. Subsequent interactions use this stored copy for rapid user identification, avoiding repeated complex recognition processes and minimizing interaction time.
3Ease of operation
If personal information is stored and retrieved based on voiceprint, then user experience is improved, but the system complexity increases
Solution Approach 1:
The system introduces a personal information management module as an intermediary between voiceprint recognition and response generation. This module handles the storage, retrieval, and management of personal information including user profiles, preferred tones, and interaction history. By centralizing these functions in a dedicated intermediary module, the system manages complexity while providing comprehensive personalization services that improve user experience.

AI summary
Embodiments of this application provide a voice interaction method. The interaction method includes: An electronic device receives a first voice signal, where the first voice signal includes a wake-up word. The electronic device switches from a standby state to a working state based on the wake-up word, and the electronic device outputs a second voice signal in a first tone, where content of the second voice signal is used to respond to content of the first voice signal, the first tone is obtained based on personal information associated with a voiceprint feature of the first voice signal, the personal information associated with the voiceprint feature of the first voice signal includes personal information corresponding to a first registered voice signal, and in a plurality of registered voice signals, a voiceprint feature of the first registered voice signal is most similar to the voiceprint feature of the first voice signal. In the embodiments of this application, communication is performed in a tone that meets a user requirement, thereby improving user experience.
