Analysis and synthesis of the three-dimensional movements of the head, face, and hand of a speaker using cued speech.

In this paper we present efforts for characterizing the three dimensional (3-D) movements of the right hand and the face of a French female speaker during the audiovisual production of cued speech. The 3-D trajectories of 50 hand and 63 facial flesh points during the production of 238 utterances were analyzed. These utterances were carefully designed to cover all possible diphones of the French language.
