语音编码在聋生唇读汉字语音识别中的作用

The Phonological Code Effect for the Deaf Students in Lipreading Chinese Phonetic Identification

本研究探讨了聋生唇读汉字语音识别中语音编码、助听器、音素可见性的作用。结果表明,编码方式、助听器与音素之间的交互作用在正确率和反应时上都显著,音素可见性在唇读汉字语音识别过程中作用明显,助听器明显作用于单韵母语音识别过程。尽管语音编码、口形运动编码与手指语编码共同作用于聋生唇读汉字语音识别的过程,但手指语编码与口形运动编码的作用明显不如语音编码,语音编码内在强力支持着聋生唇读汉字语音识别的过程,起着中间调节器的功能。

This is a study on the role of phonological encoding, hearing aids and phonemes in deaf students＇ phonetic identification of Chinese words in lipreading. Some results of the experiment are as follows. The interaction among encoding ways, phonemes, and hearing aids is significant both in acuracy rater and response time. The visibility plays an important role in phonetic identification, while hearing aids have a significant function in the identification of single vowels. The phonological code, and the finger language code, and the mouth moving code all act on lipreading, but the phonological code as a coordinator, backs up phonetic identification.
