Handshape and coarticulation in ASL fingerspelling

Using a new dataset of ASL fingerspelling, we have annotated variation in handshapes in order to quantify coarticulation between handshapes. We found variation of handshapes with increased ulnar digit flexion (AKA baby handshapes) in the handshapes for -C-, -D-, -E-, and -O-. We found that there is variation across speakers, across handshapes, and finally across surrounding environments. Flexed ulnar digits in handshapes surrounding -E- and -O- encourage increased ulnar digit flexion in the target -E- and -O-. We therefore demonstrate that both distinctive and allophonic features can trigger assimilation.
