RECENT DEVELOPMENTS IN FACIAL ANIMATION: AN INSIDE VIEW
1998 (English)In: Proceedings of International Conference on Auditory-Visual Speech Processing / [ed] Burnham, D., Robert-Ribes, J. & Vatikiotis-Bateson, E., 1998, 201-206 p.Conference paper (Other academic)
We report on our recent facial animation work to improve the realism and accuracy of visual speech synthesis. The general approach is to use both staticand dynamic observations of natural speech to guidethe facial modeling. One current goal is to model the internal articulators of a highly realistic palate, teeth, and an improved tongue. Because our talkinghead can be made transparent, we can provide ananatomically valid and pedagogically useful displaythat can be used in speech training of children withhearing loss . High-resolution models of palateand teeth  were reduced to a relatively smallnumber of polygons for real-time animation . Forthe improved tongue, we are using 3D ultrasound data and electropalatography (EPG)  with errorminimization algorithms to educate our parametricB-spline based tongue model to simulate realisticspeech. In addition, a high-speed algorithm has beendeveloped for detection and correction of collisions, to prevent the tongue from protruding through the palate and teeth, and to enable the real-time displayof synthetic EPG patterns.
