The speech perception abilities of 37 children with cochlear implants (single-channel or multichannel) were examined as a function of age at onset of deafness. There was no significant difference in the speech perception abilities of implanted children who were born deaf and those of implanted children who lost their hearing during the first 3 years of life. In contrast, the performance of children whose age at onset of deafness was 5 years or later was significantly better than that of the children with congenital or early-acquired deafness on tests of stress pattern categorization, closed-set word identification, open-set identification of common phrases, and lipreading enhancement.
对37名接受了人工耳蜗植入（单通道或多通道）的儿童的言语感知能力进行了研究，该能力是耳聋起始年龄的函数。先天性耳聋的植入儿童与在生命的头3年内失聪的植入儿童的言语感知能力没有显著差异。相比之下，在重音模式分类、闭集单词识别、常用短语的开集识别和唇读增强测试中，耳聋起始年龄为5岁或更大的儿童的表现明显优于先天性或早发性耳聋的儿童。
