EXPRESSING EMOTIONS IN FACIAL ANIMATION

Based on the author's speechreading study and the development of 3D modelling, a Hungarian talking head has been created. Our general approach is to use both static and dynamic observations of natural speech to guide the facial modelling. A three level dominance model has been introduced that takes coarticulation into account. Each articulatory feature has been grouped to dominant, flexible or uncertain classes. The acoustic speech and the articulation are linked with each other by a synchronising process. There are a couple of features added to improve the naturalness of articulation. Basic emotions defined by Ekman can be expressed in a scalable and blended manner.
