长沙方言单字调及变调的实验语音学报告

长沙方言单音节声调及双音节变调的实验语音学研究发现,单音节声调包括阳去21和上声42两个降调和阴平23,阳平13,阴去45,入声24四个升调;没有平调。变调有三种形式:阳去做前字时,调值由21变为22;上声无论做前字或是后字,均由42变为33;入声做后字时,在并列或偏正结构中由24变为33。

An Acoustic Study of Citation Tones and Tone Sandhi in Changsha Chinese

This article reports an acoustic investigation of citation tones and tone sandhi in Changsha Chinese. The results show that, acoustically, all citation tones are either in a rising shape or in a falling shape, i.e., there is not a level tone in citation form (T1 23; T2 13; T3 42; T4 45; T5 21; T6 24). In contrast to citation form, tone shapes resulting from tone sandhi are of level. Shangsheng (T3) changes from 42 to 33 no matter it is in the former or latter position of the disyllabic sequences. The pitch value of the changed tone of Rusheng (T6) is also 33 in disyllabic sequences. But only when it resides on the 2nd syllable within the modifier head or coordinate structures, does the pitch value undergo changes.
