新派上海话全浊擦音中的清声成分分析

A study of the voiceless portion in voiced fricatives in the New Shanghainese

本文主要研究了新派上海话全浊擦音单念时声母清声和浊声的时长关系。结果表明上海话的全浊擦音内部存在很多不同的清浊变体。由于影响因素比较复杂,我们引入国外学界近年来开始使用的线性混合效应模型,统计后发现最主要的影响因素是声母类型,其次是发音人,而韵母类型并没有显著影响。此外,我们也证明了全浊擦音变异虽然与全浊塞音变异表现不同,但仍然是平行的音变现象。

This study investigates the temporal ratio of the voiceless to voiced portions in the voiced fricatives in the New Shanghainese. It shows that the phonological voiced fricatives in Shanghainese are variant from voiceless fricatives to voiced fricatives. With the linear mixed-effects model, the paper reveals that place of articulation is the primary factor that affects the different portions of voiceless in fricatives. It also proves that the alternation of voiced and voiceless variations for phonological voiced fricatives is in parallel with the variants of voiced stops in Wu dialects.
