人工耳蜗中的粗音高信息可能会阻碍语言发育前儿童用户的歌唱发展。在本研究中，7名植入人工耳蜗的舌前聋儿童（5.4至12.3岁）唱一首他或她最熟悉的歌曲，对照组由14名听力正常的儿童（4.1至8.0岁）组成。提取了录制歌曲中每个音符的基频（F0）。基于参考乐谱计算以下五个度量：（1）相邻音符的F0轮廓方向，（2）整首歌曲的F0压缩比，（3）跨音符的归一化F0的平均偏差，（4）音高间隔的平均偏差，以及（5）音符持续时间差的标准偏差。与听力正常的儿童相比，植入人工耳蜗的儿童在基于音高的评估中表现出明显较差的表现。在基于节律的测量中，两组之间没有显著差异。由于无法在正确的方向上操纵音高并产生准确的音高高度，植入人工耳蜗的语言前发育儿童在唱歌方面有明显的缺陷。未来的研究，大样本量是必要的，以占歌唱表演的大变异。
The coarse pitch information in cochlear implants might hinder the development of singing in prelingually-deafened pediatric users. In the present study, seven prelingually-deafened children with cochlear implants (5.4 to 12.3 years old) sang one song that was the most familiar to him or her. The control group consisted of 14 normal-hearing children (4.1 to 8.0 years old). The fundamental frequencies (F0) of each note in the recorded songs were extracted. The following five metrics were computed based on the reference music scores: (1) F0 contour direction of the adjacent notes, (2) F0 compression ratio of the entire song, (3) mean deviation of the normalized F0 across the notes, (4) mean deviation of the pitch intervals, and (5) standard deviation of the note duration differences. Children with cochlear implants showed significantly poorer performance in the pitch-based assessments than the normal-hearing children. No significant differences were seen between the two groups in the rhythm-based measure. Prelingually-deafened children with cochlear implants have significant deficits in singing due to their inability to manipulate pitch in the correct directions and to produce accurate pitch height. Future studies with a large sample size are warranted in order to account for the large variability in singing performance.
