Experimental Study on Citation Tone of Dingxi Dialect in Gansu Province

Abstract

Based on the recorded corpus of field investigation, this paper uses experimental phonetics to conduct an experimental study on the citation tone of Dingxi dialect, and uses the acoustic analysis software Praat to extract the fundamental frequency parameters of the experimental materials, and analyzes frequency mode of the citation tone of Dingxi dialect. The experimental results show that Dingxi dialect has three tones of Pingsheng, Shangsheng, and Qusheng. Among them, the Pingsheng does not distinguish between yin and yang, and it is a rising tone with a tone pitch of 24; the Shangsheng is a falling tone with a tone pitch of 51; the Qushneg is a flat tone with a tone pitch of 33. Comparing the existing research results on Dingxi citation tone, it is concluded that the citation tone pattern obtained by the phonetic experiment is consistent with the conclusions obtained by traditional methods, but there are slight discrepancies in the description of tone values.
