TV Voice Recognition Microphone Switching by User Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice assistant systems in TVs struggle to accurately determine which microphone to use for voice recognition based on user intention, leading to inefficiencies and potential misinterpretation of user commands.
Innovation Solution
An information processing apparatus and method that selectively uses either the main body microphone or the remote control microphone based on user operations, such as pressing a button, uttering a wake word, or interacting with a graphical user interface, to ensure voice recognition aligns with user intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system uses both main body microphone and terminal microphone for voice detection, then the adaptability to different user operations is improved, but the device complexity increases due to the need to switch between microphones
Solution Approach 1:
The system dynamically switches between the main body microphone and terminal microphone based on the detected user operation state. The control unit changes the active microphone according to whether the user is performing local operations or remote operations, making the system adaptable without requiring permanent complex multi-microphone configurations for all scenarios
Solution Approach 2:
The control unit automatically determines which microphone to use based on the operation state detection, eliminating the need for manual user selection. The system self-adjusts the microphone configuration based on the detected operation type, reducing the burden on the user while maintaining adaptability
2Measurement precision
If the system automatically switches microphones based on operation state, then the voice recognition accuracy is improved, but the loss of time occurs during the switching process
Solution Approach 1:
The control unit proactively switches the microphone before the voice recognition process begins, based on the detected operation state. By preparing the correct microphone in advance rather than switching during voice input, the system minimizes time loss while ensuring accurate voice capture from the appropriate source
3Ease of operation
If the system uses terminal microphone for remote operations, then the ease of operation is improved, but the reliability of voice detection may deteriorate due to distance and environmental factors
Solution Approach 1:
The terminal acts as an intermediary device that captures the user's voice locally through its microphone and transmits it to the main body. This intermediary approach allows users to operate remotely with ease while maintaining reliable voice detection, as the terminal microphone captures the voice in proximity to the user rather than relying on the main body microphone to capture distant sounds
