Abstract

Methods and systems are provided for displaying transcriptions of radio communication transcription for an aircraft. The method comprises capturing audio signals of radio communication traffic to and from the aircraft. The captured audio signals are preprocessed to divide the signals into independent spoken utterances. Each spoken utterance is transcribed using a speech recognition decoder that utilizes an air traffic control (ATC) speech recognition model and classification data is extracted from the transcription of each spoken utterance. The transcription of each spoken utterance is logged with reference to the classification data and a textual display of the transcription is provided to a crew member of the aircraft.

First claim

What is claimed is:

1. A method for displaying transcriptions of radio communication transcription for an aircraft, comprising:
capturing audio signals of radio communication traffic to and from the aircraft;
preprocessing the captured audio signals to divide the signals into independent spoken utterances;
transcribing each spoken utterance using a speech recognition decoder that utilizes an air traffic control (ATC) speech recognition model;
extracting classification data from the transcription of each spoken utterance;
logging the transcription of each spoken utterance with reference to the classification data; and
providing a textual display of the transcription of each spoken utterance to a crew member of the aircraft,
wherein:
the textual display comprises separate sub-displays for: (i) messages for the aircraft, (ii) messages from the aircraft, and (iii) unrecognized messages, and
the textual display further comprises a swipe arrow for moving messages from one sub-display another.

2. The method of claim 1 , where the ATC speech recognition model comprises an acoustic recognition model.

3. The method of claim 1 , where the ATC speech recognition model comprises an lexicon recognition model.

4. The method of claim 1 , where the ATC speech recognition model comprises an language recognition model.

5. The method of claim 1 , where the extracted classification data comprises an aircraft call sign.

6. The method of claim 1 , where the extracted classification data comprises an aircraft tail number.

7. The method of claim 1 , where the extracted classification data comprises a traffic message.

8. The method of claim 1 , where the extracted classification data comprises a message for the aircraft.

9. The method of claim 1 , where the extracted classification data comprises a possible message for the aircraft.

10. The method of claim 1 , where the extracted classification data comprises an unrecognized message.

11. The method of claim 1 , where the logs of the transcriptions are uploaded to cloud based data storage.

12. The method of claim 1 , where the logs of the transcriptions are stored in audio log storage.

13. The method of claim 1 , where the logs of the transcriptions are stored in data log storage.

14. An apparatus for displaying transcriptions of radio communication transcription for an aircraft, comprising:
a communications receiver that captures audio signals of radio communication traffic to and from the aircraft;
a preprocessor that divides the captured audio signals into independent spoken utterances;
a speech recognition decoder that transcribes each spoken utterance using an air traffic control (ATC) speech recognition model;
a postprocess that extracts classification data from the transcription of each spoken utterance;
a log manager that logs the transcription of each spoken utterance with reference to the classification data; and
a textual display that displays the transcription of each spoken utterance to a crew member of the aircraft,
wherein:
the textual display comprises separate sub-displays for: (i) messages for the aircraft, (ii) messages from the aircraft, and (iii) unrecognized messages, and
the textual display further comprises a swipe arrow for moving messages from one sub-display another.
