Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice recognition in display devices is impaired by surrounding noise and distance from the device, leading to reduced command recognition rates.
Innovation Solution
A display device that uses audio data from peripheral devices, such as remote controls or Bluetooth speakers, to enhance voice recognition by synchronizing location and delay times, and compensating for noise through preprocessing data adjustments based on movement detection and communication speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If voice recognition is performed using only the display device's microphone, then the device complexity is low, but the voice recognition accuracy deteriorates due to surrounding noise and distance
Solution Approach 1:
The patent combines the display device's microphone with peripheral devices' microphones to form a unified voice recognition system. The controller integrates audio data from multiple sources, synchronizing them based on position and delay time to achieve accurate voice recognition while maintaining relatively simple individual device structures.
2Measurement precision
If audio data from peripheral devices is used to enhance voice recognition, then the voice recognition accuracy improves, but the device complexity increases due to additional communication and synchronization requirements
Solution Approach 1:
The controller is designed to perform multiple functions: it controls the display device's own microphone, receives and processes audio data from peripheral devices, synchronizes multiple audio sources, and performs voice recognition. This multi-functionality reduces the need for separate dedicated components, managing complexity while enhancing performance.
3Adaptability or versatility
If the peripheral device moves, then the adaptability of the system improves, but the voice recognition accuracy deteriorates due to changes in audio data quality and synchronization
Solution Approach 1:
The system dynamically adjusts to peripheral device movement by continuously updating position information and recalculating delay times for audio synchronization. The controller receives position data from the moving peripheral device and modifies the audio data processing accordingly, maintaining voice recognition accuracy despite changes in the audio environment.
4Measurement precision
If audio data is continuously received from peripheral devices, then the voice recognition accuracy improves, but the loss of time increases due to data transmission and processing delays
Solution Approach 1:
The system performs preliminary synchronization of audio data from peripheral devices before voice recognition processing. Position information and delay times are calculated in advance, and audio data is pre-processed and synchronized, reducing the time required for actual voice recognition and minimizing overall processing delays.
