Solution Overview
Problem
Current digital devices face challenges in improving voice recognition rates, particularly when performing Acoustic Echo Cancellation (AEC) functions, especially in environments with multiple speakers, where existing methods struggle to accurately process audio data within a preset distance.
Innovation Solution
A digital device and method that involves accessing a relay to detect external devices within a preset distance, sending audio reference data to these devices, and utilizing this data for enhanced AEC functions across multiple speakers, thereby improving voice recognition rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If audio data is processed from multiple speakers to improve voice recognition, then voice recognition rate is improved, but device complexity increases
Solution Approach 1:
The patent segments the audio processing task by identifying and separating audio data from individual speakers within the preset distance. Each speaker's audio reference data is processed independently through AEC functions, allowing the system to handle multiple sources without overwhelming complexity. The segmentation enables targeted processing of relevant audio sources while ignoring others.
Solution Approach 2:
The patent introduces a relay as an intermediary component that facilitates communication between the digital device and external devices. The relay receives audio reference data from external devices and transmits it to the digital device, simplifying the overall system architecture by centralizing the coordination function and reducing direct complexity in the main processing path.
2Measurement precision
If AEC function is performed using audio data within preset distance, then voice recognition accuracy is improved, but loss of information increases
Solution Approach 1:
The patent applies preliminary action by pre-processing audio reference data before it is used in AEC functions. The system receives and stores audio reference data from external devices in advance, preparing it for subsequent processing. This preliminary collection and organization of audio data ensures that when AEC processing occurs, the necessary information is already available and properly formatted, minimizing information loss during the actual cancellation process.
