A Comparative Study On Ancient Chinese Dialects Phonetics System

A Comparative Study of the Ancient Dialect is an inevitable choice to construct the original language,explore dialect features.Historical comparison and geographical features comparison are main methods of our study.it is noteworthy that geographical features comparison is first proposed,aimed at revealing dialect features through the difference of the presence or absence of sound relationships,phonetic conditions,phonological background,phonetic mechanism.This research is an attempt to combine comparative methods with sound change theory.Historical comparison is mainly used to explore controversial issues about ancient initials study.Comparative study on dialect features is mostly by geographical features comparison.The first chapter is about the velar source of dental consonants.Firstly,four liquid consonants-l-,-lj-,-j-,-l’-should be reconstructed as one set-l->-j-.It is phoneric conditions lead to their difference.Secondly,dental cosonants derived from vear cosonants all should be reconstruct as Cl-.Their difference is result of phonetic conditional variant.Thirdly,part of l->j-in medievalis sound systems is from ancient fi-.The third chapter is about the reconstruction of the devoiced nasals.It is proposed that there was only one set of devoiced nasals,that is m,n,(?).Devoiced nasals should convert to their corresponding asperational voiceless initials.However,the limitations of phonological structure,sound conditions and other factors led to other irregular evolution directions.The fifth chapter is aimed at exploring the dialect geography of the relationships of支,脂,之 rhyme-categories.There is significant differences between the northern and southern region.支,脂 are close in the northern region,while 脂,之 are close in the southern region.there are also two secondary categories in the northern region.There are much less consonant restrictions in Qilu region than Qinjin region.Chapter VI is about the relationship between the rhyme-categories sets 支、锡、耕 and 歌、月、元。支、歌 relaitionship in northern region is more close than the southern region,instead of the opposite situation which is advocated by other scholars.Qilu region toke place耕*e(?)>en,元*en>e sound change,thus thers is no consonant constriction on the relationship between 耕*e(?)and 元*en.The same situation happened to the relationship between 元*en and支*e.However the relationship between the two rhyme-categories sets was limited on velar consonants.
