A Parametric Tongue Model for Animated Speech

We present a tongue model for use in computer-animated speech. The model is capable of representing tongue shapes during the production of English vowels and consonants as well as general motion of the tongue. Geometrically, the model is composed of a NURBS surface with 60 control points and an 8 + 13 grid of bi-cubic patches. We also present a parameterization of the model that requires only 6 parameters for use during speech production.
