制约汉语连读变调的韵律因素

The Influence of Prosodic Factors on Chinese Tone Sandhi

汉语连读变调受到韵律因素的制约,是韵律结构的实现方式。变调规则的作用域及变调过程中声调的变化特征等方面均可以从韵律的角度进行考查。基于优选论的研究主要涉及关联连读变调域与韵律词、韵律短语及语调短语等不同层级韵律单位的同界制约条件和限制声调调节次数及调型变化的制约条件等。

The Chinese tone sandhi is to maintain and present particular prosodic structures. Tone sandhi domain and features of tonal change can be well explored in terms of prosodic factors. The current study, based on Optimality Theory, basically puts forward two types of constraints, including the constraints aligning tone sandhi domain with such prosodic units as prosodic word, prosodic phrase and intonational phrase, and the constraints regarding tonal modulation and tonal amplitude.
