当涂湖阳方言声调格局及同型调声学特征研究

Study on the Tone Pattern and Homophonic Acoustic Characteristics of Dangtu Huyang Dialect

摘要: 本文采用实验语音学方法研究当涂县湖阳镇方言的声调格局，通过声学实验得出湖阳方言单字调有七个，调类调值分别为：阴平55、阳平224、上声33、阴去335、阳去51、阴入334、阳入41；研究发现湖阳方言七个调类的时长存在明显差异；本文还考察湖阳方言单字调的主体分布及各声调曲线稳态段、动态段的分布情况——平调(阴平、上声)、阴去调和阴入调整个调均为稳态段，阳平调的稳态段位于调干和调尾，降调(阳去、阳入)的稳态段位于调头和调干；最后分析湖阳方言四组同型调在时长、基频、起/尾点音高、拐前段音高等方面的区别性声学特征。

Abstract: In this paper, the experimental phonetics method is used to study the tone pattern of Huyang Town dialect in Dangtu County. Through acoustic experiments, it is concluded that there are seven monosyllabic tones in Huyang dialect. The tone values are : Yinping 55, Yangping 224, Shangsheng 33, Yinqu 335, Yangqu 51, Yinru 334, Yangru 41; it is found that there are obvious differences in the duration of the seven tones in Huyang dialect. This paper also examines the main distribution of monosyllabic tones in Huyang dialect and the distribution of steady-state and dynamic segments of each tone curve. The flat tone (yinping, shangsheng), yinqu and yinru adjustment are all steady- state segments. The steady-state segment of yangping tone is located in the dry and tail, and the steady-state segment of falling tone (yangqu, yangru) is located in the head and dry. Finally, the distinctive acoustic characteristics of the four groups of homophonic tones in Huyang dialect are analyzed in terms of duration, fundamental frequency, starting / ending pitch, and pre-turn pitch.
