A fast and precise speech-triggered tongue animation system by combining parameterized model and anatomical model

A 3D realistic tongue system is proposed. Firstly, the muscle geometry and fiber arrangement are specified after a tongue mesh model is constructed from medical data. Secondly, with the target of the efficiency and realism of animation, the tongue tissues, including tongue muscles, are described by combining a fast parametric model and a precise anatomical model to simulate the active and passive mechanical characteristics. The experiments demonstrate the suitability of the system for speech visualization.
