A Method of Mouth-shape''s Shape Recognition Forward to Chinese Speech Recognition
一种面向汉语语音识别的口形形状识别方法*

This paper presents in detail a statistical method and implementation of mouth-shape's shape recognition and gray level based on perfect image features of mouth shapes at the level of vowels recognition. The results of the recognition experiments approximately accord with the reasoning evaluations. The recognition rate is over 80% for five vowels' mouth-shapes. It proposes a beneficial associate approach for language's voice wave recognition.
