Voice Recognition Sound Output Control by Device Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of multiple electronic devices in the same space can reduce the voice recognition rate of voice recognition devices due to noise from other devices, necessitating a method to selectively control sound output to enhance recognition performance.
Innovation Solution
A sound output control system that uses a server to transmit sound output stop commands to electronic devices connected via a network, allowing for selective control of sound based on the location of the voice recognition device, thereby reducing noise interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound output is reduced from all electronic devices to improve voice recognition rate, then voice recognition performance is improved, but sound output functionality is degraded
Solution Approach 1:
The system segments electronic devices by their physical location relative to the voice recognition device. Devices are divided into two groups: those in the same space (which may cause interference) and those in different spaces (which generally do not interfere). This segmentation allows selective sound output control - muting only devices in the same space while preserving sound output from devices in different spaces, thus improving voice recognition without completely degrading sound output functionality.
2Reliability
If sound output is muted from electronic devices in the same space to reduce noise interference, then voice recognition rate is improved, but sound output functionality is degraded
Solution Approach 1:
The system applies different sound output control policies to different locations. Electronic devices in the same physical space as the voice recognition device are subjected to sound output restriction, while devices in different spaces maintain normal sound output functionality. This local differentiation ensures that voice recognition performance is improved in the critical near-field area without unnecessarily degrading sound output functionality elsewhere.
3Reliability
If location-based selective sound control is implemented, then voice recognition rate is improved while maintaining sound output from distant devices, but system complexity is increased
Solution Approach 1:
The system introduces a server as an intermediary component that coordinates between the voice recognition device and multiple electronic devices. The server receives information about the voice recognition device's location and current operation state, then automatically determines which electronic devices should have their sound output restricted. This intermediary approach distributes the control logic complexity to the server, keeping the individual electronic devices relatively simple while achieving sophisticated location-based sound control.
