A Study On The Construction Of The Basic Phonetic Resource Base Of The Yi Language A-Du Dialect

Yi A-du dialect belongs to the northern dialect of Yi language,which is mainly used in Bu Tuo County,Ning Nan County and Pu Ge,Zhao Jue,De Chang,Jin Yang,Hui Dong,Hui Li and other areas of Liangshan Yi Autonomous Prefecture,Si Chuan Province.At present,about 600000 Yi people use A-du dialect.It is the most effective and valuable way to preserve and inherit the A-du dialect,which has the characteristics of Polyphony and consonant.According to the standard of language investigation,this paper formulates the text of Yi A-du speech sound investigatio.At the same time,it uses corpus,mysql,web program and other technologies to complete the construction and application development of Yi A-du basic speech resource database.This paper mainly discusses and analyzes the following six chapters:The foreword part: around the research background and significance of the Yi language A-du dialect,expounds the use scope,situation and phonetic characteristics of the A-du dialect,combined with the protection strategies of the endangered ethnic languages in China,puts forward the goal of building the phonetic resource base.The first chapter: the analysis of the phonetic characteristics of the Yi Adu dialect,respectively from the three dimensions of vowels,consonants and tones to illustrate the phonetic characteristics and phonological characteristics of the Yi A-du dialect,and complete the summary.The second chapter: the speech data processing of the Yi language ardu language,which includes the design and processing of the survey text.The specific practice of voice field survey,specific in-depth use of the core area of Bu Tuo in A-du voice data collection,according to the plan to complete the collection of corpus and sorting out the Yi,Chinese translation,international phonetic symbols corresponding to 32753 characters.The third chapter: the construction and management of the basic voice resource base of Yi A-du dialect.Through the analysis of the structure system of the voice resource base,it is proposed to complete the construction,management and application of the basic voice resource base of Yi A-du dialect with both the front and back system and the ethnic style by PHP + My SQL + Apache technology.Chapter four: Based on the corpus,the acoustic parameter database and vowel analysis of Yi Adu dialect include two aspects,one is to complete voice annotation and classification storage.On the other hand,we use Praat voice analysis platform to analyze the voice data,establish the acoustic parameter database and complete the statistics and analysis of the experimental voice angle,and complete the vowel map of A-du.Conclusion part: summarize the highlights and characteristics of the research,analyze the shortcomings,and clarify the follow-up improvement of the research needs.
