西充方言“轻声、儿化”调值中平现象研究

A Study of the Middle-Flat Tone of Light Tone and the Retroflex Suffixation in Xichong Dialect

西充方言属于入声独立区,中古入声字独立一调,调值中平(33);但音系中的中平调不仅仅只表示中古入声字的调值,还出现于轻声、儿化音以及叠音词的次音节上,这便造成了调类和调值的错位。文章认为,这样的错位,首先源于儿化等语法层面因素的渗透,渐渐导致语音的弱化;而其调值与入声的趋同,则源自音系内部的整化原则的系统整合。

There is an independent Rusheng tone in Xichong dialect, as an independent tone category, its tone pitch is 33. The middle-flat tone not only represents the Rusheng tone, but also appears in the sec-ond syllables of the light tone, retroflex suffixation and reduplicated words in this dialect, which have causes the dislocation between tone category and tone pitch of the sound system. This paper considers that the dislo-cation originates from the influence of grammar factors like retroflex suffixation, which leads to the reduction of sound. At the same time, based on the intergralization principle of the sound system, they share the same tone pitch.
