研究普通话人工耳蜗 (CI) 用户的词汇声调感知和旋律音高感知之间的关系，并研究先前的声学听力对 CI 用户的言语和音乐感知的影响。对 21 名语前和 11 名语后年轻（年龄：6-26 岁）说普通话的 CI 用户进行了词汇声调感知和旋律轮廓识别 (MCI) 的测量。词汇声调识别针对四种声调模式进行测量：声调 1（降 F0）、声调 2（升 F0）、声调 3（降升 F0）和声调 4（降 F0）。 MCI 使用 9 个五音符旋律模式进行测量，其中包含音高轮廓的变化以及音符之间不同的半音间距。词汇声调识别总体良好（总体平均值 = 81% 正确），并且受试者组之间没有显着差异。 MCI 表现普遍较差（平均 = 23% 正确）。语后 CI 参与者（平均正确率为 32%）的 MCI 表现明显优于语前 CI 参与者（正确率为 18%）。纠正异常值后，语前或语后 CI 参与者的词汇声调识别与 MCI 表现之间不存在显着相关性。仅对于语后参与者来说，耳聋年龄与 MCI 表现显着相关。对于语前和语后参与者来说，CI 经验与 MCI 表现显着相关。仅对于语前参与者来说，耳聋持续时间与音调识别显着相关。尽管普通话中音高提示很普遍，但目前的 CI 参与者在感知旋律音高方面存在很大困难。词汇音调中幅度和持续时间线索的可用性很可能弥补了这些 CI 听众观察到的不良音调感知。之前的声学听觉体验似乎有利于语后 CI 用户的旋律音高感知。对于两个受试者组来说，较长的 CI 体验与更好的 MCI 表现相关，这表明 CI 用户的音乐感知可能会随着他们使用设备的经验的增加而提高。
To examine the relationship between lexical tone perception and melodic pitch perception in Mandarin-speaking cochlear implant (CI) users, and to investigate the influence of previous acoustic hearing on CI users’ speech and music perception. Lexical tone perception and melodic contour identification (MCI) were measured in 21 prelingual and 11 postlingual young (age: 6–26 years old) Mandarin-speaking CI users. Lexical tone recognition was measured for four tonal patterns: Tone 1 (flat F0), Tone 2 (rising F0), Tone 3 (falling-rising F0), and Tone 4 (falling F0). MCI was measured using 9 five-note melodic patterns that contained changes in pitch contour, as well as different semitone spacing between notes. Lexical tone recognition was generally good (overall mean = 81% correct), and there was no significant difference between subject groups. MCI performance was generally poor (mean = 23% correct). MCI performance was significantly better for postlingual (mean = 32% correct) than for prelingual CI participants (18% correct). After correcting for outliers, there was no significant correlation between lexical tone recognition and MCI performance for prelingual or post-lingual CI participants. Age at deafness was significantly correlated with MCI performance only for postlingual participants. CI experience was significantly correlated with MCI performance for both prelingual and postlingual participants. Duration of deafness was significantly correlated with tone recognition only for prelingual participants. Despite the prevalence of pitch cues in Mandarin, the present CI participants had great difficulty perceiving melodic pitch. The availability of amplitude and duration cues in lexical tones most likely compensated for the poor pitch perception observed with these CI listeners. Previous acoustic hearing experience seemed to benefit postlingual CI users’ melodic pitch perception. Longer CI experience was associated with better MCI performance for both subject groups, suggesting that CI users’ music perception may improve as they gain experience with their device.
