Aircraft Voice Recognition Contextual Feedback System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice recognition systems in aircraft lack contextual feedback, causing increased workload for flight crews when recognized voice commands are not executed, as users must manually scroll through screens to determine the reason for non-execution.
Innovation Solution
A voice recognition system that includes a voice recognition controller and an application controller, which convert voice commands to avionics system commands, determine if the commands can be performed, and provide feedback on display devices or aural devices when they cannot be executed, including reasons for failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voice recognition systems are implemented in aircraft, then voice command recognition capability is improved, but user workload increases when commands are not executed due to lack of feedback
Solution Approach 1:
The system implements a feedback mechanism that automatically provides contextual information to users when voice commands are not executed. The application controller generates and displays messages explaining why commands cannot be performed, eliminating the need for users to manually check system screens and reducing workload while maintaining voice recognition capabilities
2Loss of information
If manual screen checking is required to determine command execution status, then system information completeness is improved, but time consumption and workload increase
Solution Approach 1:
The system performs preliminary action by proactively generating and displaying feedback messages before users need to manually check system screens. The application controller automatically determines command execution status and provides explanations in advance, saving users time and effort in investigating command failures

AI summary
A voice recognition system in an aircraft is provided. The voice recognition system includes: a voice recognition controller configured to receive a voice command from a flight crew member voice interface, convert the voice command to an avionics system command, and forward the avionics system command to an avionics system for execution. The voice recognition system further includes an application controller configured to: receive the avionics system command that has been converted from the voice command; determine whether the avionics system command can be performed; cause the avionics system command to be performed when it is determined that the avionics system command can be performed; and when it is determined that the avionics system command cannot be performed, generate a message that provides a reason why the avionics system command cannot be performed and cause the message to be displayed on a display device and/or annunciated on an aural device.
