本研究探讨了植入人工耳蜗（CI）的聋哑儿童在必须学习语音相似的单词时的语音处理。46名34至78个月大的法语聋哑儿童与CI进行了测试，在16个不同的试验。在每次试验中，他们首先接受两个词-对象配对的训练，然后呈现第三个对象，并用熟悉的单词之一标记。孩子们被要求将之前标记的物体之一与第三个（相同标记的）物体相匹配。每一对词都通过一个或几个语音特征在首辅音或首元音上进行对比。实验结果表明，聋儿认知障碍者能够在词和物体之间建立新的指称联系。然而，他们的表现低于以前在正常听力儿童（NH）中观察到的表现。在这种情况下，他们正确地处理涉及几个语音特征的对比，但在最小的对比中表现出困难。在单词学习过程中招募精细语音敏感性的能力似乎主要受植入物使用时间的影响，植入后3年内性能总体增加。无实足年龄效应，也无植入年龄对处理质量的影响。困难与最小的对比度和没有任何年龄在这个年龄范围内的植入效果进行了讨论，根据最近的研究词汇development.Learning成果：阅读这篇文章后，读者将能够认识到的知觉技能的儿童人工耳蜗植入体和区分那些知觉功能，儿童难以感知。爱思唯尔公司出版
The present study explores phonetic processing in deaf children with cochlear implants (CIs) when they have to learn phonetically similar words. Forty-six 34-to-78-month-old French-speaking deaf children with CIs were tested on 16 different trials. In each trial, they were first trained with two word-object pairings, and then a third object was presented and labeled with one of the familiar words. Children were asked to match one of the previously labeled objects with the third (same-labeled) object. Each pair of words contrasted on either the initial consonant or the first vowel by one or several phonetic features. The results show that deaf children with CIs are able to establish a new referential link between a word and an object. However, their performance is lower than that previously observed in normal-hearing children (NH). In such a situation, they process contrasts involving several phonetic features correctly, but show difficulties with minimal contrasts. The ability to recruit fine phonetic sensitivity during word learning appears to be influenced mainly by duration of implant use, with an overall increase of performance during the 3 years after implantation. There was no chronological age effect, nor age at implantation effect on the quality of processing. Difficulty with minimal contrasts and the absence of any age at implantation effects in this age range are discussed in light of recent studies on lexical development.Learning outcomes: After reading this article, the reader will be able to recognize the perceptual skills of children with cochlear implants and distinguish those perceptual features that are difficult for the children to perceive.
