Experimental Analysis of the Pitch of Chinese Declarative Sentences by Uyghur Native Speakers Based on Speech Analysis Platform

Based on the investigation and experimental analysis of the pitch of Uyghur native speakers' Chinese declarative sentences, the experimental results show that the intonation of Uyghur learners shows similar pitch downward inclination characteristics as native speakers. Compared to native speakers, Uyghur learners have a narrow range of words. In the word tone range, the word tone range in the sentence is the smallest, the first word of the sentence is second, and the last word of the sentence is the largest. The Chinese intonation of Uyghur native speakers is also influenced by their mother tongue, showing the characteristics of a large decrease in the upper line of the word tone range at the end of the sentence, and the fluctuation of each word tone. Based on the current research status and the research idea of “intonation pattern”, this paper investigates the Chinese intonation acquisition of Uyghur native speakers from three aspects: word intonation domain, word intonation domain and sentence intonation domain, in order to further expand and improve the research on Chinese intonation acquisition of native speakers of ethnic languages in China.
