A New 3D Lip Model For Analysis and Synthesis Of Lip Motion In Speech Production

This work presents a methodology for 3D modeling of lip motion in speech
production and its application to lip tracking and visual speech animation.
Firstly, a geometric modeling allows to create a 3D lip model from
30 control points for any lip shape. Secondly, a statistical analysis,
performed on a set of 10 key shapes, generates a lip gesture coding
with three articulatory-oriented parameters, specific to one speaker.
The choice of the key shapes is based on general phonetic observations.
Finally, the application for lip tracking of the 3D model controlled
by the three parameters is presented and evaluated.
