A Study Of Three Rising Tones In Xubu Dialect Of Duchang

In this study,three rising / winding tones with rising segments in Duchang-Xubu dialect(a Gang Chinese dialect)are studied.Experimental phonetics and Statistics are used as the main research methods to describe and analyze these three tones.This paper studies the overall tone pattern of Duchang xubu dialect and the characteristics and differences of its three rising tones,sums up the rules of the evolution of tone types,and by measuring the VOT of stops and affricates,the paper further discusses the synergistic effect of initial consonants and tones in tone opposition in Duchang-Xubu dialect in the process of phonetic evolution.This article is divided into four chapters:The first chapter is the introduction.This chapter introduces the geography,history and administration of Duchang,briefly introduces previous researches of the Duchang dialect,sums up previous findings on its phonological features.By comparing previous research findings,it is found that previous classifications of Duchang rising / dipping tones are inconsistent,and the disagreements mainly falls on the rising/dipping tones.At last,this chapter expounds the research aim,content and significance of this paper.The second chapter describes the experimental study of monosyllabic tone fundamental frequency of Duchang.This chapter first introduces the experimental design,and then,by analyzing the fundamental frequency curve chart of monosyllabic tones and the ending pitch of the tone and inflection point of curve,sums up the tone categories of the senior and young speakers,and demonstrates the main pitch distribution of each tone category,by drawing distribution charts of pitch cntours.The third chapter is about the initial consonants of the three rising tones and the relationship between VOT and pitch.With the experiments in this paper,it is proved that the three rising tone is in the process of "Near-Merger".The Fourth Chapter is the conclusion.It summarizes the research results and innovations of this paper,and puts forward the shortcomings of this paper.
