Aircraft Speech Recognition Automatic User Profile Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current speech recognition systems on aircraft require manual selection of user profiles, which is inconvenient and may lead to lower recognition rates, especially when multiple users need to use the system simultaneously.
Innovation Solution
A method that integrates speech recognition and speaker recognition to automatically identify users and select corresponding profiles in real-time, allowing for seamless transition between users without manual intervention, using a speech recognition unit with components for receiving, speaker recognition, and speech recognition to process speech signals effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user profile selection is implemented in speech recognition systems, then users can select their preferred profile, but the operation becomes inconvenient and time-consuming especially when multiple users need to use the system simultaneously
Solution Approach 1:
The system automatically identifies users through speaker recognition technology and selects appropriate speech recognition profiles without requiring manual user intervention. The speech recognition unit performs speaker recognition on incoming speech signals, automatically matches speakers to their corresponding profiles, and applies the appropriate profile for speech-to-text conversion, enabling the system to serve itself rather than requiring users to manually select profiles
Solution Approach 2:
User profiles are pre-configured and stored in the system before actual use. During an enrollment phase, user voice characteristics are recorded and processed to create speaker profiles that are ready for automatic identification. This preliminary preparation allows the system to quickly and accurately identify users and apply appropriate profiles without requiring time-consuming manual selection during actual speech recognition tasks
2Measurement precision
If speaker-dependent speech recognition is used to improve recognition accuracy, then recognition rates improve, but users must perform user-based training and manual profile selection before use
Solution Approach 1:
The system merges speaker recognition functionality with speech recognition functionality into a unified automated process. The speaker recognition unit and speech recognition unit work together seamlessly, where speaker recognition automatically identifies the user and retrieves their profile, which is then applied by the speech recognition unit. This combination eliminates the need for separate manual profile selection and training procedures while maintaining high recognition accuracy
Solution Approach 2:
The system performs automatic user identification and profile selection without requiring users to manually initiate training procedures or select profiles. The enrollment process is automated where users simply speak and their voice characteristics are automatically captured and processed to create profiles. During actual use, users are automatically identified and their profiles are automatically applied, eliminating complex manual setup procedures
3Adaptability or versatility
If multiple users share a speech recognition system, then system versatility improves, but manual profile selection becomes necessary and reduces operational efficiency
Solution Approach 1:
The system automatically identifies which user is speaking and selects the appropriate profile without requiring manual intervention. Multiple users can be enrolled in advance, and when a user speaks, the system automatically recognizes their voice characteristics, retrieves their stored profile, and applies it for speech-to-text conversion. This automated multi-user support maintains high operational efficiency while supporting system versatility
Solution Approach 2:
The speech recognition system is designed to universally support multiple users through a single unified interface. The system incorporates both speaker recognition and speech recognition capabilities that work together to automatically handle multiple users. Each user has their own profile stored in the system, and the system can switch between different user profiles automatically based on who is speaking, providing multi-user support without requiring separate devices or complex manual configuration

AI summary
The present disclosure relates to a method of performing speech recognition on board of an aircraft, to a computer program for executing the method, as well as to a speech recognition unit for performing speech recognition on board of an aircraft. The method comprises: receiving (S202) a speech signal spoken by a user; performing speaker recognition (S204) on the speech signal to identify the user from the speech signal; selecting (S206) a speech recognition user profile which is associated with the identified user; and performing speech recognition (S208) on the speech signal using the selected user profile.
