BERTraffic: BERT-based Joint Speaker Role and Speaker Change Detection for Air Traffic Control Communications. (arXiv:2110.05781v3 [eess.AS] UPDATED)

Automatic speech recognition (ASR) allows transcribing the communications
between air traffic controllers (ATCOs) and aircraft pilots. The transcriptions
are used later to extract ATC named entities, e.g., aircraft callsigns. One
common challenge is speech activity detection (SAD) and speaker diarization
(SD). In the failure condition, two or more segments remain in the same
recording, jeopardizing the overall performance. We propose a system that
combines SAD and a BERT model to perform speaker change detection and speaker
role detection (SRD) by …
