A study of sign language coarticulation

Abstract

This paper presents a coarticulation-modeling project in French Sign Language (LSF). We briefly introduce what sign language is about and why we study a specific part of it: to coarticulate isolated signs in order to create parameterized utterances. Then we explain what coarticulation means and how it has been studied in several research fields. We describe the methodology we have set up to reach our goal: creation of sign corpora, annotations of these corpora, analysis of these annotations, and finally design of a coarticulation model. The evaluation process will be made by different kind of people in various pieces of software.
