摘　　要：本研究采用3×6两因素被试内实验设计,探讨了编码方式和视素可见性对听觉障碍学生唇读汉语元音识别的影响。结果表明,编码方式和视素可见性共同交互作用于唇读汉语元音识别过程,在正确率和反应时上都表现显著,视素可见性和编码方式在识别效果上表现出不同的特点,视素可见性在唇读汉语元音识别中的作用显著,语音编码在唇读汉语元音识别中发挥着中间调节器的功能。We explored the role of the encoding ways and the visibility of visemes for hearing handicapped students in lipreading Chinese vowel recognition, and obtained some results as follows. The interaction of the encoding ways and the visibility of visemes is significant in correctness and response time. The encoding ways and the visibility of visemes show different characteristics respectively in the vowel recognition. The results show that viseme visibility has an effective function in lipreading Chinese vowel recognition, and phonological code plays a significant role as a coordinator.
