Vowel change caused by breathy voice in words of yangping(阳平)tone in the Putao pinghua(平话)of Guangxi:In comparison with its counterpart in the Lin'gui Liutang pinghua
This paper discusses the vowel change of words with breathy voice in yangping(阳平)tone in the Yangshuo Putao pinghua(平话)of Guangxi.The paper proposes that such vowel change is not influenced by the pitch,falling/rising tone or the duration of tone,nor by the voiced initial;It should be an outcome of strong breathy voice.In the neighbouring pinghua of Lin'gui Liutang,vowel change also exists although there is no apparent breathy voice.Such a contrast suggests that breathy voice did existed originally in the Lin'gui Liutang pinghua which led to the vowel change;The later drop of breathy voice then left the differentiation of yinping(阴平)and yangping to be solely on pitch and the level/rising of tone in Lin'gui Liutang pinghua.
