Predicting Tongue Positions from Acoustics and Facial Features

Asterios Toutios, Slim Ouni

We test the hypothesis that adding information regarding the positions of electromagnetic articulograph (EMA) sensors on the lips and jaw can improve the results of a typical acoustic-to-EMA mapping system, based on support vector regression, that targets the tongue sensors. Our initial motivation is to use such a system in the context of adding a tongue animation to a talking head built on the basis of concatenating bimodal acoustic-visual units. For completeness, we also train a system that maps only jaw and lip information to tongue information.
