本文采用与传统口说耳辨完全不同的语音实验的方法,运用科学的手段,即使用praat软件研究滕州方言单字声调。在实验分析的过程中,提取滕州方言单字调的音高值,并将音高值换算成log值,然后用excel表格绘出音高曲线,从而得出五度值。通过实验研究,最终得出滕州方言有阴平、阳平、上声和去声四个调类。 In this paper, we use a completely different method of phonetic experiment from the traditional method of speaking ear and use scientific means to study the tone of Tengzhou dialect with praat software. In the process of experimental analysis, we extracted the pitch of Tengzhou dialect, and converted the pitch value into log value, then plotted the pitch curve with excel table to get the fifth degree value. Through experimental research, finally come to Tengzhou dialect Yin Ping, Yang Ping, on the sound and the sound of four tone class.
