PURPOSE
The speech-perception abilities of 36 French children, whose onset of deafness occurred before 2 years of age, was longitudinally examined after they received a Nucleus multichannel cochlear implant.
METHODS
Speech perception was assessed in four areas: phoneme detection, closed-set word and sentence recognition; and modified open-set recognition.
RESULTS
All children achieved phoneme detection by 3 months after implantation. Closed-set word and sentence recognition appeared initially less accurate in children with congenital deafness than in the prelingually deafened children; however, these differences disappeared by 18 months after implantation. Some modified open-set recognition was evident by 12 months after implantation and continued to improve 3 years after implantation.
CONCLUSIONS
Data demonstrate significant improvements in speech perception with implant experience: 15 (60%) of 25 of the children identified sentences in closed sets, 22 (88%) of 25 identified words in closed sets after 12 months' experience, and 13 (81%) of 16 demonstrated open-set recognition after 24 months of implant use.
目的
对36名在2岁前开始失聪的法国儿童在接受Nucleus多通道人工耳蜗植入后，对其言语感知能力进行纵向研究。
方法
从四个方面评估言语感知能力：音素检测、限定词表单词和句子识别；以及改良的非限定词表识别。
结果
所有儿童在植入后3个月时均实现了音素检测。先天性失聪儿童最初的限定词表单词和句子识别准确性低于语前聋儿童；然而，这些差异在植入后18个月时消失。植入后12个月时，一些改良的非限定词表识别能力明显出现，并在植入后3年持续改善。
结论
数据表明，随着植入经验的增加，言语感知能力有显著提高：25名儿童中有15名（60%）在12个月的经验后能够识别限定词表中的句子，25名中有22名（88%）能够识别限定词表中的单词，16名中有13名（81%）在植入使用24个月后表现出非限定词表识别能力。
