摘要

The visual components of speech are the subject of research in resent years. The motivation of this paper is to suggest the concept of signature for visualized speech. These visual signatures are defined for basic components of mouth movement corresponding to sound units. Therefore, an accurate and unified database for perception and generation of visual speech could be organized. Toward this aim, mathematical tools and processes are suggested for concluding the speech related visual units. The lip geometry is parameterized with feature points. The main interpolation tool has been chosen as the Barycentric Lagrange interpolation (BLI). It can include the mouth geometry's structure dynamically during articulation in mathematical form. The outcomes (experimental models) of proposed approach associate mathematical expressions. Such method could be successor of lip tracking and identification algorithm in both lip reading and visual speech animation systems.
