维吾尔语无声间歇的声学特征

An Experimental Study of Silent Pauses in Uyghur

分析了维吾尔语连续语流中三种语速（中速、慢速和快速）的朗读方式对无声间歇声学特征的影响，利用声学分析的方法对无声间歇的两个主要声学表现：无声段的时长和出现频率（个数）进行了实验数据样本的采集与统计分析。实验数据表明：维吾尔语无声间歇的时长遵循左倾性和对数正态分布规律；无声间歇的时长和出现频率均随着韵律边界层级的升高而增加；维吾尔族发音人通过改变无声间歇的出现频率和边界后无声间歇时长来配合语速的变化。

The goal bf the present paper is to carry out production experiments of silent pauses in Uyghur. Considerable attentions are given to the changes in occurrences and duration of silent pauses across three tempos （normal. slow and fast） of Uyghur language. The results of the experiments indicate that the distribution of silent pause duration is skewed to the left and follows a log-normal distribution; both the occurrences and duration of silent pauses are increasing with the upgrading of prosodic boundaries; when there is a change in tempo, Uyghur speakers tend to vary both the occurrences and duration of silent pauses to support that change. The findings are in line with the previous studies.
