Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of reducing sound output from electronic devices located near voice recognition devices to enhance voice command recognition rates, as ambient noise from these devices can degrade the recognition performance.
Innovation Solution
An electronic device equipped with communication circuitry to detect voice recognition devices within a specified range, storing their identification information, and controlling sound output based on matching identification information received from a server to ensure sound is only suppressed 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 to improve voice recognition rate, then voice recognition rate is improved, but sound output quality deteriorates
Solution Approach 1:
The system applies different sound output control strategies to different electronic devices based on their spatial relationship with the voice recognition device. Devices detected within a specified distance range have their sound reduced or stopped, while devices outside this range maintain normal sound output. This localized approach improves voice recognition without unnecessarily degrading overall sound quality across all devices.
Solution Approach 2:
The controller acts as an intermediary between the communication device (which detects voice recognition devices) and the sound output system. It receives identification information, compares it with stored data, and determines whether to adjust sound output based on the spatial relationship. This intermediary control mechanism enables selective sound management that balances voice recognition needs with sound output quality.
2Measurement precision
If sound output is stopped or reduced from electronic devices, then voice recognition rate is improved, but device functionality deteriorates
Solution Approach 1:
The system dynamically adjusts sound output based on real-time detection of voice recognition devices and their spatial relationships. The controller continuously monitors for the presence of voice recognition devices within the specified distance range and adjusts sound output accordingly. This dynamic adaptation allows the device to maintain full functionality when voice recognition is not needed while improving recognition rates when voice commands are being input.
Solution Approach 2:
Sound output control is applied selectively only to devices within the specified distance range of the voice recognition device, leaving other devices unaffected. This localized control preserves the functionality and adaptability of the overall system while addressing voice recognition needs in the relevant spatial context.
3Measurement precision
If identification information comparison is performed to control sound output selectively, then voice recognition rate is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary detection of voice recognition devices and stores their identification information in advance. When a voice command is detected, the controller compares the received identification information with the pre-stored information to determine whether to adjust sound output. This preliminary action approach simplifies the control process by having identification data ready before voice recognition occurs, reducing the complexity of real-time decision-making.
