口语教学对听觉障碍学生唇读语音识别技能发展的作用研究

本研究以65名听觉障碍学生为被试,采用2×3两因素混合实验设计探讨了音素可见性与口语教学在唇读语音识别中的作用。结果发现,教学方式与音素可见性的交互作用在正确率上表现显著,在反应时上不显著。音素的可见性在唇读语音识别过程中作用显著,识别单韵母、复韵母、声母的正确率依次降低,反应时逐渐延长。口语教学有利于促进听障学生唇读技能的发展,主要体现在单韵母、复韵母识别过程,而在声母识别中作用不显著。

Speech Recognition Technology Applied to Intelligent Mobile Navigation System

The capability of human_computer interaction reflects the intelligent degree of mobile navigation system.The navigation data and functions of mobile navigation system are divided into system commands and non_system commands in this paper.And then a group of speech commands are abstracted.This paper applies speech recognition technology to intelligent mobile navigation system to process speech commands and does some deep research on the integration of speech recognition technology with mobile navigation system.The navigation operation can be performed by speech commands,which makes human_computer interaction easy during navigation.Speech command interface of navigation system is implemented by Dutty ++ Software,which is based on speech recognition system _Via Voice of IBM.Through navigation experiments,navigation can be done almost without keyboard,which proved that human_computer interaction is very convenient by speech commands and the reliability is also higher.
