Resumen:
In this paper, a system for speech-driven animation of generic
3D head models is presented. The system is based on the inversion
of a joint Audio-Visual Hidden Markov Model to estimate
the visual information from speech data. Estimated visual
speech features are used to animate a simple face model.
The animation of a more complex head model is then obtained
by automatically mapping the deformation of the simple
model to it. The proposed algorithm allows the animation
of 3D head models of arbitrary complexity through a
simple setup procedure. The resulting animation is evaluated
in terms of intelligibility of visual speech through subjective
tests, showing a promising performance.
