听障学生唇读语音识别编码方式的实验研究

Empirical Research on Encoding Ways of Chinese Phonetic Identification for Hearing Handicapped Students in Lipreading

本研究探讨了听障学生唇读语音识别中不同编码方式和音素可见性的影响。结果表明,编码方式和音素识别可见性之交互作用在正确率和反应时上皆无显著差异,音素可见性在听障学生唇读语音识别过程中作用明显。听障学生运用三种编码方式唇读语音识别效果相当,但加工速度存在差异,差异主要来源于手指语编码与口型运动编码的识别。

The study explores the influence of encoding ways and the visibility of phonemes exerted on phonetic identification for hearing handicapped students. It is found that interaction between encoding ways and visibility of phonemes is neither significant in correctness nor in response time. The visibility of phonemes plays an important role in phonetic identification. Three coding modes make almost no difference in phonetic identification, but there exists difference in response time whose root reason lies in the identification of finger language code and mouth moving code.
