Voice Correction Device Adapting Acoustic Levels via User Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice correction devices fail to effectively adjust voice levels based on user audibility, often relying on predefined settings rather than real-time user feedback, leading to inconsistent voice clarity.
Innovation Solution
A voice correction device that includes a detector for user responses, a calculator for acoustic characteristic amounts, an analyzer for outputting these amounts, a storage unit for storing them, and a correction unit that adjusts voice signals based on comparisons between calculated and stored acoustic characteristics, ensuring the voice is easily heard by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If predefined voice correction settings are used, then device complexity is reduced, but voice clarity and adaptability to user audibility deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the detector monitors user responses to voice output, and the controller adjusts correction amounts based on this feedback. The acoustic characteristic amount is calculated from user responses, and the correction unit dynamically modifies voice signals accordingly, creating a closed-loop system that adapts to individual user audibility characteristics.
Solution Approach 2:
The patent changes the correction amount parameter dynamically based on calculated acoustic characteristic amounts. Instead of using fixed predefined settings, the system adjusts correction parameters in real-time according to detected user responses and calculated acoustic characteristics, enabling adaptive voice correction for different users and situations.
2Ease of operation
If real-time user feedback detection is implemented, then voice clarity is improved, but device complexity and processing requirements increase
Solution Approach 1:
The detector detects user responses to voice output in real-time, providing feedback to the controller. This feedback loop enables the system to accurately adjust voice correction parameters based on actual user audibility, improving adaptation accuracy while managing processing complexity through targeted real-time analysis.
Solution Approach 2:
The system preliminarily calculates acoustic characteristic amounts from detected user responses and stores them in the storage unit before applying corrections. This preliminary processing organizes data in advance, reducing real-time processing burden and simplifying the correction application process.
3Ease of operation
If dynamic voice level adjustment is performed, then user experience is improved, but processing time and energy consumption increase
Solution Approach 1:
The system performs voice correction processing periodically based on detected user responses rather than continuously. The controller adjusts correction amounts at specific intervals when user feedback is available, reducing processing time and energy consumption while maintaining effective dynamic adaptation to user needs.
