Paper Abstract

Recent research results show the recognition rates of all kinds mouth-shape recognition systems are not high enough because of the improper feature selection and extraction for mouth-shape images and the false classification for those features on the boundary of different categories. This paper presents a statistical approach, called CPMSR, for mouth-shape recognition at the phoneme level. The feature-extracting module for this approach is based on research results of phonetics and personal investigation at a deaf school. The analyzing module employs Support Vector Machine (SVM) technique, which is a useful tool dealing with boundary points problem. With these improvements our experiment achieved the satisfactory recognition rate of over 90% for 5 vowels and 24 consonants' mouth-shapes.
