Evaluation of Movement Generation Systems Using the Point-light Technique

We describe a comparative evaluation of different movement generation systems capable of computing articulatory trajectories from phonetic input. The articulatory trajectories here pilot the facial deformation of a 3D clone of a human female speaker. In this paper we test the adequacy of the predicted trajectories in accompanying the production of natural utterances. The performance of these predictions are compared to the ones of natural articulatory trajectories produced by the speaker and estimated by an original video-based motion capture technique. The test uses the point-light technique [26, 27].
