Cochlear implant (CI) users' speech understanding may be influenced by different speaking styles. In this study, speech recognition was measured in Mandarin-speaking CI and normal-hearing (NH) subjects for sentences produced according to four styles: slow, normal, fast, and whispered. CI subjects were tested using their clinical processors; NH subjects were tested while listening to a four-channel CI simulation. Performance gradually worsened with increasing speaking rate and was much poorer with whispered speech. CI performance was generally similar to NH performance with the four-channel simulation. Results suggest that some speaking styles, especially whispering, may negatively affect Mandarin-speaking CI users' speech understanding.
人工耳蜗使用者的言语理解能力可能会受到不同说话方式的影响。本研究采用四种说话方式（慢、正常、快和低语）对普通话人工耳蜗使用者和正常听力（NH）者进行了言语识别测试，四种说话方式分别为：慢、正常、快和低语。人工耳蜗使用者使用其临床处理器进行测试；NH 受试者在聆听四通道人工耳蜗模拟时进行测试。随着说话速度的增加，言语识别能力逐渐下降，而低语时的识别能力更差。使用四通道模拟时，CI 的性能通常与 NH 的性能相似。结果表明，一些说话方式，尤其是低语，可能会对普通话人工耳蜗使用者的言语理解产生负面影响。
