绍兴方言连读变调的底层声调特征

On the tone features underlying the Shaoxing tone sandhi

汉语各方言的连读变调形式极其丰富繁杂,绍兴方言就是其中之一。引起绍兴方言连读变调的原因很多,有语音环境、词汇结构、句法功能、音系制约等因素。本文只讨论连读变调的音系学层面。文章运用特征几何理论,分析底层声调特征在绍兴方言二字结构连读变调中的行为规律,发现表层声调连读变调的不同形式是底层声调特征的扩散和(或)脱落产生的结果所致。底层声调特征的行为规律是表层连读变调的音系机制。

The complexity and variety of tone sandhi forms in Chinese differ from dialect to dialect.In Shaoxing dialect,different tone sandhi forms can be phonetically,phonologically,lexically,or syntactically conditioned.This paper adopts a phonological approach to Shaoxing disyllabic tone sandhi.Through a systematic examination of the phonological behavior of tone features in sandhi domain from the perspective of feature geometry,this paper finds that the tone sandhi forms in surface representation result from the spreading and/or delinking of tone features in underlying representation.It is suggested that the underlying behavior of tone features is the phonological mechanism of tone sandhi forms in Shaoxing dialect.
