3D Models of the Lips for Realistic Speech Animation


3D models of the lips have been developed in the framework of an audiovisual articulatory speech synthetizer. Unlike most of the regions of the human face, the lips are essentially characterized by their border contours. The internal and external contours of the vermilion zone can be fitted by means of algebraic equations. The coefficients of these equations must be controlled so that the lip shape can be adapted to various speakers conformations and to any speech gesture. To reach this goal, a 3D model of the lips has been worked out from geometrical analysis of the natural lips of a French speaker. Our lip model was developed to adjust a set of continuous functions best fitting the contours of 22 reference lip shapes. Only five parameters are necessary to predict all the equations of the contours of the lip model. From this model, a volumic model based on implicit surfaces was also developped to take in account lip contact.
