BeCoS corpus: Belgian Covid-19 Sign language corpus. A corpus for training Sign Language Recognition and Translation

We are presenting the Belgian Federal COVID-19 corpus, nicknamed the BeCoS (Belgian CovidSign language) corpus. It consists of the entire archive of official press conferences from the BelgianFederal Government concerning the COVID-19 pandemic. The speakers speak mostly in Dutchor French and occasionally in German, and nearly all speech is accompanied by a deaf signer whoperforms live interpreting from what is being said. We have preprocessed the corpus with speakerdiarisation, applied Belgian Dutch ASR, and post-ASR language identification and punctuationprediction as well as signer diarisation, sign language identification and sign language keypointrecognition. The corpus is made publicly available.
