Solution Overview
Problem
Existing electronic apparatuses face challenges in efficiently processing user speech across multiple sensor devices, leading to duplication of processing and resource wastage, particularly in distributed environments like living rooms and kitchens.
Innovation Solution
An electronic apparatus is designed to prioritize sensor devices by receiving audio signals from multiple devices, identifying the most effective sensor based on similarity and operation state, and performing speech recognition only with the identified device, thereby reducing redundant processing and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensor devices receive and process user speech independently, then speech recognition coverage is improved, but processing duplication and resource wastage occur
Solution Approach 1:
The system segments the speech processing task by designating one sensor device as the primary processor while others act as secondary devices that transmit audio data without performing full speech recognition, thereby dividing the computational workload and avoiding duplication
Solution Approach 2:
The electronic apparatus acts as an intermediary that receives audio data from multiple sensor devices, determines which device should process the speech based on proximity and operational state, and routes the processing task accordingly to avoid redundant computation
2Measurement precision
If all sensor devices perform speech recognition, then recognition accuracy is improved, but network transmission and calculation resources are wasted
Solution Approach 1:
The system extracts the speech recognition function from all sensor devices and concentrates it on the primary sensor device determined by proximity and operational state, while other devices retain only the audio data transmission function, thereby reducing overall system complexity
Solution Approach 2:
The system performs preliminary determination of the primary sensor device based on proximity to the electronic apparatus and operational state before speech recognition occurs, pre-establishing which device will handle the computationally intensive recognition task
