自主言语中非流利因子的韵律特征初探

An exploration on the prosodic features of disfluencies in spontaneous speech

非流利(disfluency)是自主言语的一个重要特征。非流利现象主要指口语中出现的无声停顿(unfilled pause)、填充停顿(filled pause)、重复(repetition)及自我修复(self-repair)等。大量研究表明,非流利现象是高度规则化的事件。本研究在回顾前人研究的基础上,以ESCCL语音语料库中自主对话为语料,对中国英语专业学生自主言语中主要的非流利因子(填充停顿、重复以及自我修复)的韵律特征进行了初步探索。研究结果对加深言语生成理论理解以及英语语音教学具有一定的指导作用。

Disfluency is an important feature of spontaneous speech.It mainly refers to unfilled pause,filled pause,repetition and self-repair in spoken English.Former studies have showed that DFs are rule-governed.Reviewing studies in this field and basing on speech materials from ESCCL Corpus,this paper explores the prosodic features of DFs（filled pause,repetition,self-repair） in Chinese English majors＇ spontaneous speech.The findings,to some extent,will be helpful for the understanding of speech production theory and English phonetic instruction.
