Voice Recognition Proximity Control for Shared-Space Audio Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of sound or noise from other electronic devices in the same space as a voice recognition device reduces the voice command recognition rate, necessitating a method to selectively control sound output from these devices.
Innovation Solution
An electronic device equipped with communication circuitry to detect a voice recognition device, store its identification information, and control sound output based on received commands from a server, using Bluetooth Low Energy (BLE) for short-range communication, to either stop or reduce sound when the device is in the same space as the voice recognition device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sound output is reduced or stopped from electronic devices in the same space as a voice recognition device, then voice recognition rate is improved, but sound output quality and user experience deteriorate
Solution Approach 1:
The system applies different sound output control policies to different electronic devices based on their spatial relationship with the voice recognition device. Electronic devices detected within a specified distance range (same space) have their sound output reduced or stopped, while devices outside this range maintain normal sound output. This localized control approach improves voice recognition rate without unnecessarily degrading overall sound output quality across all devices.
2Measurement precision
If sound output is selectively controlled based on device location, then voice recognition rate is improved, but device complexity increases
Solution Approach 1:
The system introduces a server as an intermediary to manage the complex control logic. The electronic device communicates with the server, which determines whether sound output should be reduced or stopped based on the detected voice recognition device and its distance. This intermediary approach transfers the computational complexity from individual electronic devices to a centralized server, simplifying the local device architecture while maintaining sophisticated control capabilities.
3Measurement precision
If communication circuitry continuously detects voice recognition devices, then voice recognition rate is improved, but energy consumption increases
Solution Approach 1:
The communication circuitry performs detection of voice recognition devices at periodic intervals rather than continuously. The controller checks whether a voice recognition device is present within the specified distance range at scheduled times, and adjusts sound output accordingly. This periodic detection approach maintains adequate voice recognition support while significantly reducing energy consumption compared to continuous monitoring.
