Automatic Transcription of Air-Traffic Communication to Text
Nevařilová, Veronika ; Veselý, Karel (referee) ; Szőke, Igor (advisor)
This thesis focuses on fine-tuning Whisper, an automatic speech recognition model developed by OpenAI, on Czech and English recordings of air-traffic communication. It provides a fundamental insight into automatic speech recognition, neural networks and transformer architecture. Further, data collection and annotation is also described and after that it details the process and outcomes of Whisper’s training on two different transcription formats – full, where the model learns to transcribe recordings word by word, and abbreviated, which is more suitable for quick navigation and more natural for air traffic controllers.
