Voice Input Control via User Triggered Microphone Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice recognition technologies in electronic devices maintain the microphone in a constant on state, leading to noise inclusion and power consumption issues, making it difficult to accurately recognize voice articulation start and end times.
Innovation Solution
A method and apparatus that control the microphone to be in a turn-off state during voice recognition mode, with user-initiated turn-on and turn-off via touch input, touch pen input, or key input, allowing precise voice input collection and minimizing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the microphone is maintained in a turn-on state during voice recognition mode, then the terminal can automatically collect voice signals, but noise other than user voice is collected and power is consumed unnecessarily
Solution Approach 1:
The system performs preliminary detection of user input (touch, touch pen, or key input) before activating the microphone. This preliminary action ensures the microphone is turned on only when the user intends to input voice, preventing unnecessary noise collection and power consumption while maintaining automatic voice collection capability when needed
2Productivity
If the microphone is maintained in a turn-on state during voice recognition mode, then voice signals can be continuously collected, but it is difficult to accurately recognize voice articulation start and end time
Solution Approach 1:
The system uses feedback from detecting user input events (touch input, touch pen input, or key input) to control microphone activation. When user input is detected, the microphone is turned on and voice signal collection starts; when no input is detected, the microphone is turned off. This feedback mechanism provides clear start and end markers for voice articulation, enabling accurate recognition of articulation timing while maintaining continuous collection capability
3Adaptability or versatility
If the microphone is maintained in a turn-on state during voice recognition mode, then the terminal waits for voice input automatically, but power is consumed according to the operation of the microphone
Solution Approach 1:
The system dynamically adjusts the microphone's operational state based on detected user input. The microphone transitions between turn-on and turn-off states according to real-time detection of touch input, touch pen input, or key input. This dynamic control maintains the adaptability of automatic voice recognition mode while optimizing power consumption by activating the microphone only when user input indicates intended voice input

AI summary
A method of controlling a voice input of a terminal supporting a voice recognition function is provided. The method includes controlling a microphone to be in a turn-off state during operation of a voice recognition mode; detecting a first user input for requesting turn-on of the microphone based on at least one of a touch input, a touch pen input, and a key input; controlling the microphone in the turn-off state to be in a turn-on state when the first user input is detected; collecting voice input data of a user through the microphone in the turn-on state; and controlling the microphone in the turn-on state to be in the turn-off state when a second user input for requesting the turn-off of the microphone is detected, and terminating collecting the voice input data.
