摘要
借助汉语发音口形的生理特点,在音素识别这一水平上进行汉语语音的辅助识别,具体给出了一种口形形状识别和灰度的统计方法及其具体实现.实验结果基本与理论估算相吻合,对5个元音的口形区别正确率在80%以上。
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.
