Voice Recognition Proximity-Based Audio Muting in Shared Spaces
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 sound output based on the location of the voice recognition device.
Innovation Solution
A system where a server connected to multiple electronic devices via a network transmits sound output stop commands to devices in the same space as the voice recognition device when a voice command is detected, using identification information to determine which devices to mute or power off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sound output is stopped from all electronic devices when a voice command is detected, then voice recognition rate is improved, but sound output in different spaces is unnecessarily interrupted
Solution Approach 1:
The system divides electronic devices into different groups based on their spatial location relative to the voice recognition device. Devices in the same space as the voice recognition device are segmented from devices in different spaces, allowing differential sound output control. This segmentation enables the system to stop sound only from relevant devices while maintaining sound from unrelated devices, thus improving voice recognition without unnecessarily interrupting sound output elsewhere.
Solution Approach 2:
The system applies different sound output control policies to different spatial zones. In the local area where the voice recognition device is located, sound output is stopped to improve recognition accuracy. In other areas, sound output continues normally. This local quality approach ensures that the voice recognition rate is improved without affecting the user experience in other spaces.
2Measurement precision
If sound output is stopped from electronic devices in the same space, then voice recognition rate is improved, but device complexity increases due to location-based control
Solution Approach 1:
The server acts as an intermediary between the voice recognition device and other electronic devices. When a voice command is detected, the server receives the device information, determines the spatial relationship, and sends control instructions to appropriate devices. This intermediary approach simplifies the overall system architecture by centralizing the control logic, avoiding the need for each device to independently determine its spatial relationship with the voice recognition device.
Solution Approach 2:
The server performs multiple functions: it receives voice commands, identifies the voice recognition device, determines spatial relationships between devices, and sends control instructions. This multi-functionality reduces the need for separate dedicated components for each task, thereby managing system complexity while achieving the desired voice recognition improvement.
3Object-affected harmful factors
If all electronic devices are muted when a voice command is detected, then noise reduction is achieved, but usability in different spaces is degraded
Solution Approach 1:
The system segments electronic devices based on their spatial location, distinguishing between devices in the same space as the voice recognition device and devices in different spaces. Sound output is stopped only from devices in the same space, while devices in different spaces continue to output sound normally. This segmentation reduces noise in the voice recognition area without degrading usability in other spaces.
Solution Approach 2:
The system applies noise reduction locally to the space where the voice recognition device is located, rather than globally across all spaces. By controlling sound output on a local basis, the system reduces harmful noise factors in the relevant area while maintaining sound output usability in other areas, thus resolving the contradiction between noise reduction and usability.
