Prototyping and Transforming Visemes for Animated Speech

Animated talking faces can be generated from a set of predefined face and mouth shapes (visemes) by either concatenation or morphing. Each facial image corresponds to one or more phonemes, which are generated in synchrony with the visual changes. Existing implementations require a full set of facial visemes to be captured or created by an artist before the images can be animated. In this work we generate new, photo-realistic visemes from a single neutral face image by transformation using a set of prototype visemes. This allows us to generate visual speech from photographs and portraits where a full set of visemes is not available.
