Contextual Semi-Supervised Learning: An Approach To Leverage Air-Surveillance and Untranscribed ATC Data in ASR Systems [article]

Juan Zuluaga-Gomez and Iuliia Nigmatulina and Amrutha Prasad and Petr Motlicek and Karel Veselý and Martin Kocour and Igor Szöke
2021 arXiv   pre-print
Air traffic management and specifically air-traffic control (ATC) rely mostly on voice communications between Air Traffic Controllers (ATCos) and pilots.  ...  Initially, we represent in a WFST the contextual knowledge (i.e. air-surveillance data) of an ATCo-pilot communication.  ...  Finally, the novelty of our approach is that SSL can further leverage contextual knowledge, bypassing the burden of lack of annotated data (which is the case for most of the ATC use-case applications).  ...
