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 poss…
A 3-dimensional convolutional neural network is trained on unlabeled ultrasound video to predict an upcoming tongue image from previous ones. The network obtains results superior to those of simpler predictors and provides a starting point for exploiting the higher-level representation of the tongue…
This article describes a contour-based 3D tongue deformation visualization framework using B-mode ultrasound image sequences. A robust, automatic tracking algorithm characterizes tongue motion via a contour, which is then used to drive a generic 3D Finite Element Model (FEM). A novel contour-based 3…
