1. A computer-implemented method for generating photo-realistic facial animation with speech, comprising: generating in a computer storage medium a statistical model of audiovisual data over time, based on acoustic feature vectors and visual feature vectors from audiovisual data of facial features during a set of utterances; generating using a computer processor a visual feature vector sequence using the statistical model corresponding to an input set of acoustic feature vectors for speech with which the facial animation is to be synchronized; creating using a computer processor a photorealistic image sample sequence from an image library using the generated visual feature vector sequence; and applying the photorealistic image sample sequence to a three dimensional model of a head to provide the photo-realistic facial animation synchronized with the speech.
