Voice-to-Text Command Confirmation for Vehicle Traffic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle operators in traffic control systems, such as air and maritime traffic control, face challenges in deciphering verbal commands due to communication clarity issues and distractions, leading to the need for enhanced communication to ensure accurate command comprehension and reduce errors.
Innovation Solution
A voice-to-text decoding module is integrated into the vehicle control system, converting audio commands to text, extracting instructions, updating the vehicle's plan, and displaying them for confirmation, thereby ensuring accurate command integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice commands are transmitted through communication channels, then vehicle operators can receive instructions, but communication clarity deteriorates due to channel interference and distractions
Solution Approach 1:
The patent introduces a voice-to-text decoding module as an intermediary between the communication channel and the vehicle operator. This module converts received voice commands into text form, providing a clearer and more reliable representation of the instructions while filtering out communication channel interference and distractions.
Solution Approach 2:
The patent replaces the purely auditory mechanical system with an electro-optical system. Voice commands are converted into visual text display, allowing operators to process instructions visually rather than auditorially, thereby overcoming communication clarity issues and operator distractions.
2Productivity
If operators rely on auditory processing of voice commands, then communication can occur, but operator mental burden increases and errors occur
Solution Approach 1:
The patent substitutes auditory processing with visual processing by displaying converted text commands on a display device. This allows operators to read and verify commands visually, reducing mental burden and improving accuracy while maintaining productivity.
Solution Approach 2:
The patent implements a feedback mechanism where converted text commands are displayed to operators for verification. This feedback loop allows operators to confirm command accuracy before execution, thereby improving reliability and reducing errors.
3Reliability
If voice commands are repeated for confirmation, then command accuracy improves, but communication time increases
Solution Approach 1:
The patent replaces the time-consuming auditory repetition process with immediate visual text display. Commands are converted to text and presented to operators instantly, eliminating the need for repeated verbal confirmations while maintaining high accuracy through visual verification.
Solution Approach 2:
The patent performs preliminary conversion of voice commands to text before operator confirmation is needed. This preliminary action prepares the command information in a easily verifiable format, reducing the time required for subsequent confirmation steps while ensuring accuracy.
Data Source
AI summary
In some aspects, a voice to text decoding module receives audio data indicating one or more flight commands for an aircraft and from an air traffic control system, converts the audio data into text data indicating the one or more flight commands, analyzes the text data to determine the one or more flight commands, provides for display on a screen the determined one or more flight commands, receives a confirmation signal of the displayed one or more flight commands, modifies a flight plan of the aircraft so the aircraft complies with the confirmed one or more flight commands, and transmits flight control instructions corresponding to the modified flight plan to a control system of the aircraft.
