When paired with a Stratus Audio Cable, the ATC Radio Transcription feature works similar to visual voicemail. ATC communications are converted into text and displayed directly above the audio playback line, providing a helpful visual assist for referencing previous audio clips. This enables pilots to receive a clearance, ATIS, or other important ATC communications without needing to write them down.
The speech recognition and language understanding technology that drives the Radio Transcription feature was custom-designed by our Artificial Intelligence (AI) division.
At a global scale, speech recognition, translation, and transcription features are commonplace (e.g. Alexa and Siri). However, ATC communications present many challenges for these common speech recognition systems. The high rate of speech, noisy signal, narrow frequency band, and unique location identifiers are among those challenges. We identified that shortfall in the existing technology and set out to develop a speech recognition system customized for aviation.
We also use Natural Language Processing to interpret the output of the speech recognition system and present it in a more pilot-friendly format. For example, tail numbers, altitudes, runways, and frequencies are transcribed in a way that will be more helpful to pilots.
