This study examined the variables that contribute to the large individual differences in the speech perception skills of children with the Nucleus multichannel cochlear implant. Sixty-one children were tested on four measures of speech perception: two tests of closed-set word recognition, one test of open-set recognition of phrases, and one open-set monosyllabic word test, scored on the basis of the percentage of phonemes as well as words identified correctly. The results of a series of multiple regression analyses revealed that the variables of processor type, duration of deafness, communication mode, age at onset of deafness, length of implant use, and age implanted accounted for roughly 35% of the variance on two tests of closed-set word recognition, and 40% of the variance on measures that assessed recognition of words or phonemes in an open set. Length of implant use accounted for the most variance on all of the speech perception measures.
本研究调查了导致使用Nucleus多通道人工耳蜗的儿童在言语感知技能方面存在巨大个体差异的变量。对61名儿童进行了四项言语感知测试：两项闭集单词识别测试、一项短语开集识别测试和一项开集单音节单词测试，根据正确识别的音素和单词的百分比进行评分。一系列多元回归分析的结果显示，处理器类型、耳聋持续时间、交流方式、耳聋起始年龄、植入使用时长和植入年龄等变量，在两项闭集单词识别测试中约占方差的35%，在评估开集中单词或音素识别的测试中占方差的40%。植入使用时长在所有言语感知测试中占的方差最大。
