聋儿语音的声学参数分析

Acoustic Parameter Analysis of Deaf Children's Speech

目的 分析聋儿言语困难的原因，为语训工作提供其语言在语训中变化的情况。方法 对１６ 名正常儿童和２３ 名聋儿语音的基频（ＦＯ） 、共振峰（Ｆ１ 、Ｆ２ 、Ｆ３） 等参数进行分析。结果 聋儿学习语言进步慢的主要原因之一是其获得语音信息，特别是语音高频信息的能力较差。结论 应加强对聋儿感受高频语音信息能力的补偿，并在语训过程中跟踪聋儿语音的变化情况。

The fundamental frequencies(F 0)and formants(F 1、F 2、F 3)of speech in 16 normal children and 23 deaf children were analyzed.The results indicated that deaf children had poor abilities in acquiring speech information, especially those with high frequency hearing loss.So we suggest that it is necessary to provide special compensation of acquiring speech information of high frequency to deaf children,and to track acoustic changes of deaf children during their speech rtaining in order to understand their difficulties in study on time.
