广西全州才湾话单字调声学实验分析

The Experimental Analysis of Mono-syllable Tone in Caiwan Dialect of Quanzhou in Guangxi

采用实验语音学的方法分析广西全州才湾话单字调的音高特征,用Lz-score的方法对原始基频数据进行标准化处理,再根据五度标调法的原则确定各声调的调值,并将实验结果和传统方言调查结果进行比较后发现:声调调型走势跟前人记录基本一致,但具体调值略有不同;才湾话音高调值为:阴平33、阳平23、上声54、去声12。通过对比已有研究的声调结果和声学实验结果的区别,可对全州才湾话可能存在的音高演变情况进行预测。

By using the method of experimental phonetics,this paper studied the pitch feature of mono-syllabic tone of Caiwan dialect. Then,the raw data of fundamental frequency were normalized through the method of Lz-score. Next,the tone values were identified according to five notations. Finally,the experiment results and investigation results were compared to reach the conclusions as follows： the tone values of mono-syllabic tone of Caiwan dialect were yinping（ high and level tone）（ 33）,yangping（ rising tone）（ 23）,shangsheng（ falling-rising tone）（ 54） and qusheng（ falling tone）（ 12）. In addition,through comparing the differences between the existing research results and experiment results,this paper predicted the possibility of pitch change.
