基于语料库的反馈语副声道信息研究

uh，um，huh 和mm是四个常用的反馈语副声道信息。检索中国英语学习者口语语料库发现，中国英语学习者在日常对话中也会使用一些副声道信息，但使用频率较低。在对两个自建的英美影视口语语料库进行检索和分析的基础上，发现英国人和美国人对副声道信息的使用频率比中国英语学习者高，且在huh的使用上，英美两国差异显著；但mm，um和uh的使用差异不显著。副声道信息在口语会话中的功能包括作为应答的标记、作为面子威胁的缓和语、显示说话人的情感、进行修正和补充、提出问题。研究对于口语中副声道信息使用频率低的中国英语学习者具有借鉴意义。

Corpus-based Study on Non-vocal Sounds of Back-channels

uh, um, huh and mm are commonly used in people＇s daily conversation. Some non-vocal sounds are no- ticed to be used by Chinese English speakers in their conversations by retrieving SECCL （ Spoken English Corpus of Chinese Learners）. However, they do not use them often. The present paper, based on the retrieval of two self-built corpora relating to American and British movies, finds that the using frequencies of non-vocal sounds in America and Britain are comparatively higher than that in China. In terms of the using frequency of huh, Americans and British differ greatly, while the using frequencies of another three non-vocal sounds differ slightly. In addition, the present paper summarized the basic functions of these non-vocal sounds： answer mark, approach to assuage the embarrass- ment, illustration of individual＇s emotion, self-correction, follow-up, raising a question. The present paper can give a lesson to Chinese English speakers who relatively seldom use non-vocal sounds.
