Abstract: In recent year, lip-reading systems have received a great attention, since it plays an important role in human communication with computer especially for hearing impaired or elderly people. The need for an automatic lip-reading system is ever increasing. Today, extraction and reliable analysis of facial movements make up an important part in many multimedia systems such as videoconference, low communication systems, lip- reading systems. We can imagine, for example, a dependent person ordering a machine with an easy lip movement or by a simple syllable pronunciation. We present in this paper a new approach for lip localization and feature extraction in a speaker’s face. The extracted visual information is then classified in order to recognize the uttered viseme (visual phoneme). To check our system performance we have developed our Automatic Lip Feature Extraction prototype (ALiFE). Experiments revealed that our system recognizes 70.95 % of French digits uttered under natural condit ions. (More)
