User Terminal Speech Recognition Trigger During Call
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user terminals do not allow seamless integration of speech recognition functionality during call operations, as voice inputs are primarily directed to call counterparts rather than speech recognition systems, limiting the ability to process and respond to user intentions in real-time.
Innovation Solution
A user terminal equipped with a microphone, speaker, controller, and communicator that activates speech recognition upon a trigger signal, allowing simultaneous transmission of user speech to both the call counterpart and a dialogue system for processing, enabling system responses to be generated and transmitted back to the user terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voice input is directed to call counterpart during call operation, then call communication is maintained, but speech recognition functionality cannot be activated
Solution Approach 1:
The system dynamically switches the destination of voice input between call counterpart and speech recognition system based on detected trigger signals. During call operation, when a trigger signal is detected, the voice input is redirected to the speech recognition system, enabling seamless transition between call communication and speech recognition functionality without requiring separate input devices or complex user configuration.
Solution Approach 2:
The controller acts as an intermediary that receives voice input from the microphone and dynamically routes it to either the call counterpart or the speech recognition system. This intermediary function allows the system to maintain call communication while enabling speech recognition by intelligently directing voice signals to the appropriate destination based on trigger signal detection.
2Productivity
If speech recognition is activated during call, then user intention processing is enabled, but voice transmission to counterpart may be interrupted
Solution Approach 1:
The system uses periodic trigger signal detection to activate speech recognition during call operation. When a trigger signal is detected, the system temporarily redirects voice input to the speech recognition system for processing user intentions. After processing, the system returns to normal call operation, creating a periodic pattern that enables both call communication and speech recognition without continuous interruption.
3Adaptability or versatility
If voice input is simultaneously transmitted to both call counterpart and dialogue system, then speech recognition during call is enabled, but communication channel management becomes complex
Solution Approach 1:
The system extracts and separates the voice transmission paths into distinct channels: one for call counterpart communication and another for dialogue system transmission. The controller selectively activates transmission to each channel based on trigger signal detection, allowing simultaneous transmission when needed while maintaining clear channel management through selective activation rather than continuous dual transmission.

AI summary
A user terminal includes a microphone through which a speech of a user is input, a speaker through which a speech of a counterpart is output during a call, a controller configured to activate a speech recognition function upon receiving a trigger signal during the call, and a communicator configured to transmit, after the trigger signal is input, information related to the user's speech which is input through the microphone and information related to content of the call to a dialogue system that is configured to perform the speech recognition function, wherein the controller is configured to control the speaker to output a system response transmitted from the dialogue system.
