This paper describes four corpora that have been designed and built in our research team. These corpora have been recorded using motion capture (MoCap) and video equipment, and annotated according to multi-tiers linguistic templates. Each corpus has been designed for a specific linguistic purpose and is dedicated to data-driven synthesis, by (i) replacing signs or groups of signs within an utterance, (ii) replacing phonetic or phonological components and in this way modifying the grammatical or semantic aspects of the phrase, or (iii) altering prosody in the produced sign language utterances.
