聋儿汉语塞擦音发音清晰度的声学分析

Acoustic analysis on the Chinese speech anticulation of affricates for hearing-impaired children

一般认为,汉语中的辅音比元音更影响语言的可懂度。在获得辅音的过程中,“塞擦音”通常是健听儿童较难掌握的一类音。对于聋儿,更是如此。为了进一步认识聋儿难以获得塞擦音的原因,本文通过实验,以20例配戴助听器的聋儿作为实验对象,以语言学知识为基础,运用声学的知识和手段,对聋儿塞擦音(z/ts、c/ts、zh/ts、ch/t■、j/t、q/t)的获得进行分析和研究,试图找出影响聋儿获得塞擦音的规律性原因,使聋儿更好地获得塞擦音,提高言语清晰度。

In generally, consonants have effect on understanding to language more than vowels in Chinese Hearing-impaired children acquire some consonants difficultly than health children in the course of their studying speech so that it disturb their forming and developing to language. In order to know why hearing-impaired children acquired affricates diffcultly,this article based on the knowledge of linguistics,through experiment,studied and analyzed the course that hearing-impaired children acquire the affricates by acoustical knowledge and acoustical means. The authors chose 20 hearing-impaired children with hearing aids who were objects of the experiment in the study. The authors tried to find the factors which affect hearing-impaired children＇s acquiring the affricatives,so that some scientific theories could be provided which should enhance their ability to acquire affricates better and mprove their clearness to speech.
