A Study On Tone Pattern And Vowel Pattern Of Ocean Island Dialect In Changhai County

Haiyang island is one of the towns in changhai county,dalian city,liaoning province,located in the south of liaoning province.The traffic on the island is not very convenient,the environment is relatively closed,communication with the outside world is relatively little,the environment is relatively closed,the dialect features are distinct.Haiyang island dialect belongs to the yanwei small piece in the denglian piece of jiaolao official dialect.Compared with other jiaolao official dialects,it has some similarities and its own characteristics.On the basis of the existing research and by means of experimental phonetics,this paper makes a comprehensive and detailed description and analysis of oceanic island dialect from the perspective of phonetic pattern,and strives to objectively and truly reveal the phonetic features of oceanic island dialect.The paper consists of five parts:The first part is the introduction.Firstly,it gives an overall introduction to the geographical location,environment,living population,historical background,main industries and development direction of ocean island.The second is the introduction of dialects,mainly including the traditional dialects and experimental phonetics,including the study of the official dialect of jiao-liao,the dialect of liaoning province,the general study of experimental phonetics and the theory and current situation of the study of phonetic pattern.Thirdly,the reason and significance of the topic are introduced.Finally,the research methods and process are described and described.The second part is to summarize the phonology of ocean island dialect.In this paper,the phonological system of haiyang island dialect is summarized by the way of traditional phonetics and the previous research results.And compared with mandarin initials,finals,there are many obvious differences,so especially its own characteristics.The third part is to analyze the tone pattern of ocean island.This paper USES the dialect survey word list designated by the institute of linguistics of the Chinese academy of social sciences,selects the common words of haiyang island,and removes the rare words,so as to collect the corpus of the speakers.The collected corpus was screened,the effective samples were analyzed experimentally,the effective samples were segmented and marked by praat software,the fundamental frequency data were extracted and analyzed,and the data were normalized by t-value formula.Then the fundamental frequency and range of the oceanic island monotone are analyzed,and the acoustic spatial map is summarized after normalization.In the end,it is concluded that there are 4 tones and 5 different tones in the ocean island dialect,and the stability of each tone and the information provided are analyzed in detail.The fourth part is the study and analysis of the vowel pattern of ocean island dialect.This paper focuses on the analysis of first-level vowels in ocean island dialect.Therefore,in the data extraction,we need the specific values of the first three formant of first-level vowels in ocean island dialect,and conclude the rule of formant from the formant data graph.Ocean island dialect vowels,a total of seven level according to the size of the resonance peak values is different,each level of the tongue of the vowel is different before and after the water level,and using the method of V value,make first-class vowel sound bitmap and vowel V value,and then analyzed different characteristics of each level of vowels and possible trends,and comparing with putonghua vowels pattern analysis.The last part is the conclusion,which summarizes the main conclusions of each part of this paper,and makes a fair evaluation of the deficiencies.
