Speaking intelligibly is an important achievement in children's language development. How far do congenitally severe-to-profound hearing-impaired children who received a cochlear implant (CI) in the first two years of their life advance on the path to intelligibility in comparison to children with typical hearing (NH)? Spontaneous speech samples of children with CI and children with NH were orthographically transcribed by naïve transcribers. The entropy of the transcriptions was computed to analyze their degree of uniformity. The same samples were also rated on a continuous rating scale by another group of adult listeners. The transcriptions of the NH children's speech were more uniform, i.e., had significantly lower entropy, than those of the CI children, suggesting that the latter group displayed lower intelligibility. This was confirmed by the ratings on the continuous scale. Despite the relatively restricted age ranges, older children reached better intelligibility scores in both groups.
能够清晰地表达是儿童语言发展中的一项重要成就。与听力正常（NH）的儿童相比，在生命的头两年接受了人工耳蜗植入（CI）的先天性重度至极重度听力受损儿童在清晰度发展道路上能取得多大进展？天真的转录者对CI儿童和NH儿童的自发语音样本进行了正字法转录。计算转录的熵以分析其均匀程度。另一组成年听众也根据连续评分量表对相同样本进行了评分。NH儿童语音的转录更均匀，即熵显著更低，这表明CI儿童组的清晰度较低。连续量表上的评分证实了这一点。尽管年龄范围相对有限，但两组中年龄较大的儿童都获得了更好的清晰度分数。
