Due to limited spectral resolution, cochlear implants (CIs) do not convey pitch information very well. Pitch cues are important for perception of music and tonal language; it is possible that music training may improve performance in both listening tasks. In this study, we investigated music training outcomes in terms of perception of music, lexical tones, and sentences in 22 young (4.8 to 9.3 years old), prelingually deaf Mandarin-speaking CI users. Music perception was measured using a melodic contour identification (MCI) task. Speech perception was measured for lexical tones and sentences presented in quiet. Subjects received 8 weeks of MCI training using pitch ranges not used for testing. Music and speech perception were measured at 2, 4, and 8 weeks after training was begun; follow-up measures were made 4 weeks after training was stopped. Mean baseline performance was 33.2%, 76.9%, and 45.8% correct for MCI, lexical tone recognition, and sentence recognition, respectively. After 8 weeks of MCI training, mean performance significantly improved by 22.9, 14.4, and 14.5 percentage points for MCI, lexical tone recognition, and sentence recognition, respectively ( p < .05 in all cases). Four weeks after training was stopped, there was no significant change in posttraining music and speech performance. The results suggest that music training can significantly improve pediatric Mandarin-speaking CI users' music and speech perception.
由于频谱分辨率有限，人工耳蜗（CI）并不能很好地传达音高信息。音高线索对于音乐和声调语言的感知很重要；因此，音乐训练可能会提高听力任务和言语感知的表现。在这项研究中，我们调查了音乐训练对音乐感知、声调感知和句子感知的影响，参与者为 22 名年轻（4.8 至 9.3 岁）、语前聋的普通话人工耳蜗使用者。音乐感知通过旋律轮廓识别（MCI）任务进行测量。声调感知和句子感知在安静环境下进行测量。参与者接受了 8 周的 MCI 训练，使用的音高范围与测试不同。在训练开始后的 2、4 和 8 周进行音乐和语音感知测量；在训练停止后的 4 周进行后续测量。MCI、声调识别和句子识别的基线平均表现分别为 33.2%、76.9%和 45.8%。经过 8 周的 MCI 训练，MCI、声调识别和句子识别的平均表现分别显著提高了 22.9%、14.4%和 14.5 个百分点（在所有情况下，p<0.05）。训练停止 4 周后，音乐和言语感知的训练后表现没有显著变化。结果表明，音乐训练可以显著提高儿童普通话人工耳蜗使用者的音乐和言语感知能力。
