Electronic Audio Suppression Using Nearby Voice Device ID Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The recognition rate of voice recognition devices is reduced due to sound or noise output from other electronic devices located in the same space, necessitating a method to control sound output from these devices effectively.
Innovation Solution
An electronic device equipped with communication circuitry to detect voice recognition devices within a specified range, store their identification information, and compare it with received identification information to control sound output, either stopping it or reducing the volume based on matching IDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound output from electronic devices is maintained continuously, then the audio function is preserved, but the voice recognition rate deteriorates due to background noise interference
Solution Approach 1:
The system performs preliminary detection of voice recognition devices within a specified distance range before voice commands are issued. By pre-storing identification information and establishing spatial relationships in advance, the system can quickly determine whether to suppress sound output when a voice command is detected, thereby improving voice recognition rate without unnecessary delays
Solution Approach 2:
The controller acts as an intermediary between the communication device (which detects voice recognition devices) and the sound output device. It receives identification information, compares it with stored data, and mediates the sound output level based on the spatial relationship, thus resolving the conflict between maintaining audio function and reducing noise interference
2Reliability
If sound output is suppressed when voice commands are detected, then voice recognition rate improves, but the audio function deteriorates due to unnecessary sound suppression
Solution Approach 1:
The system applies different sound output control strategies to different spatial locations. Only electronic devices located within the specified distance range of the voice recognition device have their sound output suppressed, while devices in other locations maintain normal audio function. This localized approach ensures voice recognition accuracy is improved without unnecessarily affecting overall audio functionality
Solution Approach 2:
The sound output control is dynamic rather than static. The system continuously monitors for voice recognition devices within range and adjusts sound output levels in real-time based on the presence and movement of such devices. When no voice recognition device is detected, normal audio function is restored, thus avoiding unnecessary sound suppression
3Measurement precision
If identification information is stored for all detected devices, then the accuracy of sound control improves, but the device complexity increases due to additional storage and comparison operations
Solution Approach 1:
The system extracts only the essential identification information (such as device IDs or MAC addresses) from detected electronic devices and stores only this minimal necessary data. This extraction approach provides sufficient accuracy for identifying voice recognition devices while minimizing the storage burden and complexity of comparison operations, avoiding the need to store all device parameters
