摘　　要：本文从普通话卷舌元音/■/的声学特征入手,对比人工耳蜗植入(CI)儿童与健听(NH)儿童产出的普通话卷舌元音在发音清晰度及声学特征上的差异,探讨人工耳蜗植入儿童在习得卷舌元音时存在的发音困难,为该群体的语言康复教学,尤其是卷舌元音的教学,以及言语清晰度的提升提供一定的参考。发现:(1)总体而言,8.2岁左右的CI儿童能基本正确掌握卷舌元音的发音特征,但发音得分仍显著低于同龄NH儿童;(2)在不同的构词位置,CI儿童产出的卷舌元音时长均显著长于NH儿童;(3)CI儿童与NH儿童的共振峰模式存在明显差异,相比较而言,CI儿童的卷舌元音发音部位相对靠前、舌位相对较高、开口度相对较大;(4)CI儿童产出的卷舌元音卷舌色彩不浓,与NH儿童存在显著差异;(5)对于CI儿童而言,植入人工耳蜗装置的年龄与其产出卷舌元音的发音清晰度存在显著的负相关。The present paper examined the speech intelligibility and acoustic profiles of the Mandarin retroflex vowel/?/articulated by prelingually deaf children with cochlear implants,and by normal-hearing children.The main purpose is to obtain a comprehensive understanding about the difficulties CI children facing when acquiring this target vowel.The research findings may shed some light on the speech rehabilitation training,especially on the retroflex vowel training,and the improvement of speech intelligibility for children with cochlear implants.The results show that,(1)CI children,averagely aged 8.2,could produce the retroflex vowel with moderate intelligibility,but made significantly more articulatory errors than their NH counterparts;(2)CI children tended to produce the vowel with significantly longer duration in various phonetic contexts;(3)CI children showed significant difference in the formant pattern of the retroflex vowel from that of the NH group,which displayed a more front and higher articulatory position with a larger jaw opening;(4)significant differences were found in the rhoticity between the two distinct groups;(5)a negative correlation was found between the age of implantation and the intelligibility performance of the retroflex vowel.
