A new technique for representing speech articulation with an ultrasound-driven finite element model of the tongue is presented. By using a snake contour extraction algorithm with anatomically motivated constraints and a common coordinate system between the ultrasound and the tongue model, it is possible for the first time to obtain a realistic 3D simulation of the tongue directly from a non-invasive sensor (ultrasound), without mapping through any intermediate sensor modalities, and at near real-time frame rates.
