Cochlear implant (CI) users struggle with tasks of pitch-based prosody perception. Pitch pattern recognition is vital for both music comprehension and understanding the prosody of speech, which signals emotion and intent. Research in normal-hearing individuals shows that auditory-motor training, in which participants produce the auditory pattern they are learning, is more effective than passive auditory training. We investigated whether auditory-motor training of CI users improves complex sound perception, such as vocal emotion recognition and pitch pattern recognition, compared with purely auditory training.
Prospective cohort study.
Tertiary academic center.
Fifteen postlingually deafened adults with CIs.
INTERVENTION(S): Participants were divided into 3 one-month training groups: auditory-motor (intervention), auditory-only (active control), and no training (control). Auditory-motor training was conducted with the "Contours" software program and auditory-only training was completed with the "AngelSound" software program.
Pre and posttest examinations included tests of speech perception (consonant-nucleus-consonant, hearing-in-noise test sentence recognition), speech prosody perception, pitch discrimination, and melodic contour identification.
Participants in the auditory-motor training group performed better than those in the auditory-only and no-training (p < 0.05) for the melodic contour identification task. No significant training effect was noted on tasks of speech perception, speech prosody perception, or pitch discrimination.
These data suggest that short-term auditory-motor music training of CI users impacts pitch pattern recognition. This study offers approaches for enriching the world of complex sound in the CI user.
人工耳蜗（CI）使用者在基于音高的韵律感知任务上存在困难。音高模式识别对于音乐理解和理解言语韵律（表示情感和意图）都至关重要。正常听力个体的研究表明，与被动听觉训练相比，参与者发出他们正在学习的听觉模式的听觉-运动训练更有效。我们研究了 CI 用户的听觉-运动训练是否比单纯的听觉训练更能改善复杂声音感知，如语音情感识别和音高模式识别。
前瞻性队列研究。
三级学术中心。
15 名后天性耳聋的成人 CI 用户。
参与者被分为 3 个为期 1 个月的训练组：听觉-运动（干预组）、仅听觉（主动对照组）和无训练（对照组）。听觉-运动训练是使用“Contours”软件程序进行的，仅听觉训练是使用“AngelSound”软件程序进行的。
预测试和后测试检查包括语音感知测试（辅音-核-辅音、噪声中言语测试句子识别）、语音韵律感知测试、音高辨别测试和旋律轮廓识别测试。
与仅听觉组和无训练组相比，听觉-运动训练组在旋律轮廓识别任务中的表现更好（p<0.05）。在语音感知、语音韵律感知或音高辨别任务中，未观察到明显的训练效果。
这些数据表明，短期听觉-运动音乐训练可以影响 CI 用户的音高模式识别。本研究为丰富 CI 用户的复杂声音世界提供了方法。
