Voice Control System Personalizing Response Audio via Voice Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices using voice recognition technology respond with a generic computer-generated voice regardless of the user, failing to accommodate individual user preferences for voice style.
Innovation Solution
An electronic device with a voice control system that includes an obtaining module, a response determining module, a voice analyzing module, and an output control module, which analyzes user voice characteristics to select a unique response voice style from pre-stored associations, ensuring each user experiences a personalized voice response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a generic computer-generated voice is used for all users, then the device complexity is reduced and ease of operation is improved, but adaptability to individual user preferences deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-storing multiple response voices with different characteristics in a database before actual voice recognition occurs. When a user speaks, the system analyzes their voice characteristics and selects from pre-prepared responses, avoiding the need for real-time synthesis of unique voices for each user.
Solution Approach 2:
The system changes the parameter of voice characteristics by analyzing features such as pitch, tone, and speech pattern from the user's input voice. These analyzed parameters are then used to select appropriate pre-stored response voices that match the user's characteristics, enabling personalized responses without creating new voices from scratch.
2Adaptability or versatility
If voice characteristics analysis is performed to personalize responses, then adaptability to individual users is improved, but device complexity and processing requirements increase
Solution Approach 1:
The system creates copies of pre-stored response voices that match different user types rather than generating entirely new voices for each user. Multiple copies of response voices with varying characteristics are stored in advance, and the system selects and plays the appropriate copy based on voice analysis, reducing the computational burden of creating unique responses.
Solution Approach 2:
The voice characteristics and corresponding response voices are prepared and stored in advance in a database. This preliminary preparation eliminates the need for complex real-time voice synthesis and allows the system to simply retrieve and play pre-computed responses based on analyzed voice features.

AI summary
A voice control method is applied in an electronic device. The electronic device includes a voice input unit, a play unit, and a storage unit storing a conversation database and an association table between different ranges of voice characteristics and styles of response voice. The method includes the following steps. Obtaining voice signals input via the voice input unit. Determining which content is input according to the obtained voice signals. Searching in the conversation database to find a response corresponding to the input content. Analyzing voice characteristics of the obtained voice signals. Comparing the voice characteristics of the obtained voice signals with the pre-stored ranges. Selecting the associated response voice. Finally, outputting the found response using the associated response voice via the play unit.
