摘　　要：方言隶属于说话人鲁棒性问题。方言在语音、词汇、语法等方面与普通话存在一些差异,当说话人转为普通话时可能会出现母语特点的负迁移而留下口音,从而提供分析其地区或籍贯的线索。本研究选用广西的代表方言钦州话和柳州话为载体,对方言在听觉、音变、变调、频谱等方面进行声纹分析。结果表明:钦州话和柳州话存在将声调中的去声变化为阳平的特点;柳州话中的[a]、[e]、[o]等三个元音共振峰参数偏差较小,[i]和[u]两个元音的共振峰参数在F3和F4上存在部分显著差异。Dialect belongs to the problem of speaker robustness.Dialect has some phonetic,lexical,grammatical and other features different from Putonghua,and the speaker will have more or less negative transfer of the characteristics of mother tongue when switching to Putonghua,to leave behind the accent analysis region or native clues.In this study,we used Qinzhou dialect and Liuzhou dialect as the carrier to analyze the changes of the dialects in the aspects of hearing,sound change,tone change and frequency spectrum.The results show that in Qinzhou dialect and Liuzhou dialect,the dissonance in tone changes to Yangping,while in Liuzhou dialect,there is a small deviation in the parameters of three vowel formants such as[a],[e]and[o],the formant parameters of the two vowels[i]and[u]were partly significantly different in F 3 and F 4.
