Study On The Phonetic Pattern Of Gonghe In Amdo Dialect Of Tibetan

The Gonghe pastoral dialect is a sub-dialect of the Anduo dialect among the three major Tibetan dialects.Previous researchers seldom conducted systematic research on the Gonghe pastoral dialect,so the research on the Gonghe dialect is relatively rare.The case study of the Gonghe dialect is of great value in understanding the evolution of Anduo dialects.This paper uses the method of combining traditional linguistics and experimental phonetics,and introduces the idea of phonetic pattern at the same time,analyzes the law of pronunciation change and pattern distribution of Gonghe dialect,and summarizes the phonetic features and characteristics of Gonghe pastoral dialect.This article is divided into six chapters,of which chapters 2 to 5 are the main part of the full text,and chapter 6 is the conclusion.The first chapter is the introduction.First,it introduces the general situation of Gonghe County,including human geography,historical origin,general situation of the Gonghe dialect,and the current domestic and foreign research status of the Gonghe dialect of the Anduo dialect.Secondly,explain the theory of phonetic pattern and its research overview.Finally,explain the research purpose,significance,source of corpus and research methods of this article.Chapter Two,on the basis of field investigation,summarizes the phonology of Gonghe dialect and its phonological quality description,and at the same time describes and demonstrates the syl able structure of Gonghe dialect.The third chapter mainly discusses the pronunciation types and evolution of vowels and consonants in Gonghe dialect.First,it introduces the phonological classification in the traditional Tibetan grammar.Secondly,it elaborates on the comparison of the phonology of ancient Tibetan and Gonghe dialect,focusing on revealing the phonological evolution process and laws of the Gonghe dialect,and then derives the phonological characteristics of the Gonghe dialect.In the evolution of affricates,the Gonghe pastoral dialect differs from other anduo dialects in terms of affricates,such as ???????[t?] [t??] [d?] [r? ] and ???????? [kja][k?ja][gja][rgja],in ancient Tibetan are all affricates,but in the Gonghe dialect,[t?] [t??] [d?] are the palato-alveolar,[c?] [c??] [?j]and the Palatal consonant.When the front consonant [m-],[n-]is combined with a neutral(non-voiced ????????????????????????)????? [k?、t?、p?] or feminine word(voiced ?????????????????????????)????????? [g、?、d、b、?] in Tibetan,the nasal sound [m-] or [n-] is naturally brought out when pronounced,such as ?? [*p?rug] >[mt????] "cloth".、??????/??????[*p?u ru?/t?u?] >[np?? ro?] "sleeves".Chapter 4 and Chapter 5 are the phonetic pattern parts,including vowel pattern and consonant pattern(stop pattern,fricative pattern,affricate pattern).First,it introduces the basic steps of quantitative analysis in phonetic pattern research,focusing on revealing the manifestation of the phonetic pattern of Gonghe dialect,and describing its phonetic pattern objectively.The vowel pattern reflects: the distribution of the vowel [u] is a wide and long band from left to right,moving in the horizontal direction;the position of the back and half-height vowel [o] is shifted back and lower.Consonant pattern: In the pattern diagram of the three types of plosives in the Gonghe dialect,the distribution of the various plosives of women is discrete.The two c lusters in the voiceless zone are clearly distinguished,and the average VOT of aspirated voiceless plosives is significantly greater than that of men,which shows that the place of articulation of women is close to the inside of the vocal tract.Due to ge nder differences,the distribution range of each fricative has undergone tremendous changes,such as voiced fricatives [?],[?] and unvoiced fricatives [χ],[h] have a certain degree of mobility;aspirated alveolar [??] has the largest DI index,indicating that the combination of pronunciation actions is very high;the FI index of retroflex sound[t?] and palatal consonant[c??] is the smallest,indicating that the wider the friction gap,the less turbulence.
