摘　　要：目的研究不同语速和耳语式的言语是否会影响人工耳蜗植入者的言语识别效果。方法在本研究中,分别对一组人工耳蜗植入者和一组听力正常者进行以下4种不同说话方式的言语识别率测试:慢速言语、常速言语、快速言语和耳语。测试时,人工耳蜗植入者聆听由扬声器播放的未经处理的言语声,正常受试者聆听经4通道人工耳蜗处理的言语声,二者使用相同的原始测试材料。结果人工耳蜗植入组与正常对照组对4种不同说话方式的言语识别结果相似,当说话语速增加时言语识别率逐渐下降,耳语的识别率最差,对于人工耳蜗植入者来说快速言语的识别率显著低于慢速言语识别率。结论人工耳蜗植入者言语识别效果会随着所聆听言语的语速增加而降低,并且聆听耳语式的言语对人工耳蜗植入者来说是非常困难的。OBJECTIVE To find out whether cochlear implant users＇ speech recognition can be effected by speaking styles： slow,normal,fast,and whispered.METHODS In this study,speech recognition was measured in Mandarin-speaking CI and normal-hearing（NH）subjects,using 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.The primary material was the same.RESULTS CI performance was generally similar to NH performance with the four-channel simulation.Performance gradually worsened with increasing speaking rate and was poorest with whispered speech.CONCLUSION Fast speaking and whispering may negatively affect Mandarin-speaking CI users＇ speech understanding.
