In-Vehicle Voice Recognition State Display for Processing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voice recognition systems do not provide users with feedback on the state of the apparatus after voice input, leading to uncertainty about the processing status.
Innovation Solution
A voice recognition apparatus that includes a controller capable of transitioning through multiple states during voice input processing and displaying these states on a screen, allowing users to track the processing status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the voice recognition system processes voice input without displaying state information, then the processing speed is maintained, but the user cannot recognize the processing status leading to uncertainty and anxiety
Solution Approach 1:
The system implements feedback by displaying the current processing state (e.g., 'voice input', 'processing', 'voice output') on a screen during voice recognition operations. This allows users to recognize what the system is doing at each moment, reducing uncertainty and anxiety while maintaining normal processing flow.
Solution Approach 2:
The voice recognition process is divided into distinct states (voice input state, processing state, voice output state), and each state is displayed separately on the screen. This segmentation makes the complex processing transparent to users by showing only the relevant current state without overwhelming them with all possible information.
2Ease of operation
If the system displays multiple processing states on screen, then user convenience is improved through better awareness, but the interface complexity increases
Solution Approach 1:
The interface displays only the current processing state at any given moment rather than all possible states simultaneously. The system transitions through discrete states (voice input → processing → voice output), showing one state at a time, which maintains simplicity while providing complete awareness.
Solution Approach 2:
The system uses visual changes on the screen (such as text changes or indicator changes) to represent different processing states. This provides clear, intuitive feedback to users about system status without requiring complex interface elements or multiple display components.

AI summary
A voice recognition apparatus includes a controller that is configured to control a specific function in response to voice input from an occupant of a vehicle, and that is configured to sequentially transition to each of multiple states within a transition period from accepting the voice input until at least finishing controlling the specific function, and display, on a screen, which of the multiple states the controller is in.
