AVN Speech Recognition Stage-Gated Manipulation Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Audio Video Navigation (AVN) systems face issues with guiding user manipulation after speech recognition errors, leading to incomplete or incorrect commands, which can disrupt navigation and other services.
Innovation Solution
The AVN apparatus includes a sound receiver, display unit, and controller that manage speech recognition modes by displaying manipulation guide screens based on the stage of speech recognition, using thresholds, stored commands, and network connections to ensure seamless transitions from speech recognition to manipulation screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech recognition mode is used to receive user commands, then ease of operation is improved, but reliability deteriorates due to false recognition and incomplete commands
Solution Approach 1:
The system displays a manipulation guide screen that provides feedback to the user about the current speech recognition stage and expected input. This allows users to understand what the system has recognized so far and what is still needed, enabling them to correct false recognition or provide incomplete commands appropriately.
Solution Approach 2:
The speech recognition process is divided into multiple stages, with each stage corresponding to a specific manipulation guide screen. This segmentation allows the system to process speech incrementally and provide targeted guidance for each recognition stage, improving both ease of operation and reliability.
2Ease of operation
If speech recognition screen is displayed for all navigation stages, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Different manipulation guide screens are displayed according to the specific stage of speech recognition. Each guide screen is tailored to the current navigation stage (destination search, map confirmation, route selection), providing locally optimized guidance rather than a generic uniform interface.
Solution Approach 2:
The manipulation guide screen dynamically changes based on the speech recognition stage and user input. The system adapts the displayed guidance information to match the current state, making the interface flexible and context-appropriate rather than static and complex.
3Loss of information
If manipulation guide screen is displayed after speech recognition completion, then loss of information is reduced, but loss of time increases due to additional screen transitions
Solution Approach 1:
The manipulation guide screen is prepared and displayed in advance based on the speech recognition stage, before the user completes their input. This preliminary display of guidance information helps users understand what is expected next, reducing information loss and guiding them to complete the command efficiently.

AI summary
An Audio Video Navigation (AVN) apparatus includes: a sound receiver configured to receive a speech from a user; a display unit configured to display a speech recognition screen in a speech recognition mode; and a controller configured to control, if the speech recognition mode is finished at a stage, the display unit to display a manipulation guide screen corresponding to the speech recognition screen displayed at the stage.
