Mobile Terminal Voice Control via Touch-Activated Microphone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals face challenges in efficiently processing voice commands due to lengthy analysis times and low recognition rates, especially when combining touch inputs with voice inputs to determine applications and targets.
Innovation Solution
A mobile terminal system that integrates touch inputs with voice recognition, allowing users to select applications and targets through a combination of touch gestures and voice commands, reducing the length of voice commands and improving recognition rates by activating the microphone only when necessary and deactivating it to prevent incorrect operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice commands are used to control mobile terminal operations, then user convenience is improved, but voice analysis time increases and recognition accuracy decreases
Solution Approach 1:
The system pre-loads and stores multiple voice commands in advance. When a user activates voice control, the pre-stored commands are immediately available for matching, eliminating the need for real-time analysis of entire commands. This preliminary preparation significantly reduces the time required to process and execute voice instructions while maintaining ease of use.
2Ease of operation
If voice commands are used to control mobile terminal operations, then user convenience is improved, but voice recognition accuracy decreases due to incorrect recognition
Solution Approach 1:
The voice control system divides operations into two distinct phases: application selection through touch input and target selection through voice command. This segmentation allows the system to use highly accurate touch recognition for choosing the application, then use voice recognition only for the specific target within that application. By separating these functions, the system achieves high overall accuracy while maintaining voice control convenience.
3Speed
If the microphone is continuously activated for voice input, then voice command responsiveness is improved, but energy consumption increases
Solution Approach 1:
The microphone is activated periodically only when needed - specifically, when the user performs a touch input on the touchscreen. The system transitions from continuous microphone activation to event-driven activation, where the microphone turns on briefly to capture the voice command following the touch gesture, then immediately deactivates. This periodic activation pattern maintains responsiveness while dramatically reducing energy consumption compared to continuous operation.

AI summary
A mobile terminal and controlling method thereof are disclosed, by which the mobile terminal can operate based on a voice command. The present invention includes a microphone, a touchscreen, and a controller configured to activate the microphone in response to a first touch input received at the touchscreen, set a target in response to a first audio input received via the activated microphone while the first touch input is maintained at the touchscreen, and execute a specific application associated with the set target in response to releasing of the first touch input from the touchscreen or dragging in a first direction, following the first touch input.
