Research on the Tone Pattern of the Northern Jianli Dialect

本文选取湖北省监利市监北地区的荒湖管理区作为田野调查点，以该区域汉语方言的声调系统为研究对象，使用Praat声学软件提取基频数据，采用T值法进行归一化处理，绘制T值曲线图，由此确定监北方言单字调声调格局。实验结果表明，监北方言存在阴平(35)、阳平(24)、上声(31)、去声(55)四个调类，其调型与调域分布与前人基于传统方法所得结论基本吻合，本研究为监利方言内部差异及赣语官话化进程提供了实验语音学证据。This study selects the Huanghu Management District in the north of Jianli City, Hubei Province as the fieldwork site. Focusing on the tone system of the local Chinese dialect, the fundamental frequency data was extracted using Praat, and the T-value method was adopted for normalization processing. The T-value curve graph was drawn, and thus the tone pattern of the monosyllabic words in the northern Jianli was determined. Experimental results indicate that the north of Jianli City dialect possesses four tonal categories: First tone (35), Second tone (24), Third tone (31), and Fourth tone (55). The contour distribution and tonal range broadly align with conclusions derived from traditional methods in prior studies. This research provides instrumental phonetic evidence for understanding internal variations within the Jianli dialect and the ongoing Mandarinization process of the Gan dialect.
