We describe a new facial animation system based on a hierarchy of morphable sub-facial appearance models.The innovation in our approach is that through the hierarchical model, parametric control is available for the animation of multiple sub-facial areas.We animate these areas automatically both from speech -to produce lip-synching, and natural pauses and hesitations -and using specific temporal variation of appearance parameters to control sub-facial behaviours.
