Sound Output Control for Nearby Voice Recognition Devices
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 in the same space, necessitating a method to selectively control and mute sound outputs from these devices to improve voice command recognition.
Innovation Solution
A sound output control system and method that utilizes a server to transmit sound output stop commands to electronic devices connected via a network, determining the location of voice recognition devices and selectively controlling sound outputs based on their identification information to minimize noise interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound output from electronic devices is not controlled, then the audio function of electronic devices is maintained, but the voice recognition rate is reduced due to noise interference
Solution Approach 1:
The system performs preliminary detection to identify whether a voice command is being input to the voice recognition device before sound output occurs. Based on this advance detection, the system proactively controls electronic devices to stop or reduce sound output, preventing noise interference before it degrades voice recognition accuracy
Solution Approach 2:
The system continuously monitors the operational state of electronic devices and the voice recognition device, detecting sound output states and voice command input states in real-time. Based on this feedback information, the system dynamically adjusts sound output control decisions to optimize voice recognition conditions
2Reliability
If sound output is stopped from all electronic devices, then voice recognition rate is improved, but sound output from devices in different spaces is unnecessarily limited
Solution Approach 1:
The system determines the spatial location of the voice recognition device and applies sound output control selectively only to electronic devices located in the same space. Devices in different spaces maintain their normal sound output, achieving localized noise control that preserves overall system adaptability and versatility
Solution Approach 2:
The system segments electronic devices based on their spatial relationship to the voice recognition device, categorizing them into 'same space' and 'different space' groups. Sound output control is applied differently to each segment, allowing selective muting of only those devices that would interfere with voice recognition
