The method permits the animation of a synthesised model of a human face in relation to an audio signal. The method is not language dependent and provides a very natural animated synthetic model, being based on the simultaneous analysis of voice and facial movements, tracked on real speakers, and on the extraction of suitable visemes. The subsequent animation consists in transforming the sequence of visemes corresponding to the phonemes of the driving text into the sequence of movements applied to the model of the human face.
Selon l'invention, le procédé permet d'animer une maquette synthétisée d'un visage humain par rapport à un signal audio. Ce procédé est indépendant de la langue et donne une maquette de synthèse animée très naturelle, étant basée sur l'analyse simultanée de la voix et des mouvements du visage, prenant pour base des locuteurs réels, et sur l'extraction de visèmes appropriées. L'animation subséquente consiste à transformer la séquence de visèmes correspondant aux phonèmes du texte conducteur dans la séquence des mouvements appliqués à la maquette du visage humain.
