BLE-Based Sound Output Control Near Voice Recognition Devices
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 to improve recognition accuracy.
Innovation Solution
An electronic device equipped with communication circuitry to detect voice recognition devices, store 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 output when the device is within a specified distance of the voice recognition device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sound output is stopped or reduced from electronic devices in the same space as a voice recognition device, then voice recognition rate is improved, but sound output functionality is restricted
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 sound output stopped or reduced, while devices outside this range maintain normal sound output. This localized control resolves the contradiction by restricting sound only where it interferes with voice recognition.
Solution Approach 2:
The controller acts as an intermediary that receives identification information from a server, compares it with stored identification information of detected voice recognition devices, and decides whether to stop or reduce sound output. This intermediary mechanism enables automated, accurate control of sound output based on spatial relationships, improving voice recognition rate while minimizing unnecessary sound restrictions.
2Measurement precision
If electronic devices selectively control sound output based on location of voice recognition device, then voice command recognition accuracy is improved, but device complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions: detecting electronic devices around the voice recognition device, receiving identification information from the server, comparing identification information, and controlling sound output. By consolidating these functions into a single controller, the system achieves location-based sound control without proportionally increasing device complexity.
Solution Approach 2:
The electronic device automatically performs detection, comparison, and sound control operations without requiring manual user intervention. The controller autonomously determines whether to stop or reduce sound output by comparing received identification information with stored information, enabling self-service operation that simplifies user interaction despite the complexity of the control logic.
