摘　　要：本文通过对单音节字"二"的声学测量及分析,对比不同口音级别的上海普通话和标准普通话中的卷舌元音,从而为汉语语音识别系统处理卷舌元音提供相关的声学参数。本文发现:(1)从声学元音图上看,上海普通话中的男女发音人在处理卷舌元音时表现出不同,但有一趋势始终保持不变,即口音越重,舌位越靠前,且越高。(2)从共振峰模式图上看,上海普通话中的卷舌元音F3下降速度普遍比标准普通话慢,且随着口音的加重,F3下降速度越来越慢。(3)从时长上看,在上海普通话中口音加重,则相对时长较长。[],a very controversial vowel in Mandarin,has recently been shown to be a diphthong,a finding based on a large amount of acoustic and articulatory data.It is however absent in Shanghai dialect.Such difference is assumed to have some effect on Shanghai dialect speakers in their acquisition of Standard Putonghua(SP).This paper reports a contrastive study involving 54 instances of [] pronounced by 20 SP speakers and 150 instances of [] pronounced by 51 Shanghai dialect(SD)speakers in NOKIA-CASS corpus.Findings are as follows:(1)In the F1-F2 vowel charts,the position of [] in SD male speakers is located higher than those in SP ones,while in SD female speakers it is more front.But there is a general trend in both SD male and female speakers that the heavier the accent,the higher and more front the position of [].(2)Compared with SP,the third formant of [] falls much slower in SD.Meanwhile,the heavier the accent,the slower F3 falls.(3)The comparative duration of heavier accents in SD is longer than in SP.
