Contextual Speech Recognition for Aircraft Command Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft systems face challenges in accurately inputting air traffic control clearances and commands due to the risk of incomplete or incorrect inputs, which can compromise aircraft control and safety.
Innovation Solution
A contextual speech recognition system that recognizes audio inputs, identifies expected values based on the operational context, and provides graphical user interface elements for pilots to verify and modify commands, ensuring accurate execution of intended operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech recognition is used for command input, then ease of operation is improved, but measurement precision deteriorates due to incomplete or incorrect command recognition
Solution Approach 1:
The system displays the recognized voice command on a graphical interface and waits for pilot confirmation before execution. This feedback loop allows the pilot to verify the accuracy of speech recognition and correct any errors, resolving the contradiction between ease of operation and recognition accuracy.
Solution Approach 2:
The system performs preliminary verification of the recognized command by displaying it to the pilot before final execution. This preliminary action prevents incorrect commands from being executed, improving measurement precision while maintaining the ease of voice-based input.
2Productivity
If voice commands are executed directly without verification, then productivity is improved, but reliability deteriorates due to potential incorrect inputs
Solution Approach 1:
The system implements a confirmation feedback mechanism where the recognized voice command is displayed and must be confirmed by the pilot before execution. This ensures reliability by preventing incorrect inputs while maintaining productivity through rapid confirmation processes.
Solution Approach 2:
The system takes preliminary anti-action by preventing execution of potentially incorrect commands through the confirmation step. This counteracts the risk of wrong inputs before they can cause harmful effects, resolving the contradiction between speed and reliability.
3Reliability
If speech recognition system requests confirmation for all commands, then reliability is improved, but loss of time increases due to additional verification steps
Solution Approach 1:
The system applies partial verification by requesting confirmation only when necessary, rather than for all commands. This selective approach maintains reliability for critical operations while minimizing time loss for routine commands, resolving the contradiction between safety and efficiency.

AI summary
Methods and systems are provided for assisting operation of a vehicle using speech recognition. One method involves recognizing an audio input as an input voice command including a commanded value for an operational subject, automatically identifying an expected value for the operational subject that is different from the commanded value, providing a graphical representation of the input voice command on a graphical user interface (GUI) display and providing a selectable GUI element associated with the expected value for the operational subject on the GUI display. After selection of the selectable GUI element, a destination system associated with the vehicle is commanded to execute a command corresponding to the input voice command using the expected value for the operational subject.
