摘　　要：目的:对于母语为声调型的汉语普通话人群,评估人工耳蜗耦连无线调频系统(FM系统)后对言语感知力的改善效果。方法:利用中文开放式言语评估系统(MSP)为测试工具对纳入实验的11例人工耳蜗植入儿童的言语感知力进行评估。分别采用麦克风(microphone,M)、FM系统+麦克风(FM+M)2种输入方式评估受试者在不同信噪比(SNR:15、10、5、0、-5、-10dB)等条件的言语识别率的改善情况;并观察记录其在实验中的主观表现变化。结果:1在不同信噪比下测试两组言语识别率结果显示M组和FM+M组主效应间差异有统计学意义(F=72.938,P<0.01),不同信噪比之间差异有统计学意义(F=230.715,P<0.01),分组和不同信噪比水平之间存在互交效应(F=40.893,P<0.01);2实验中采用FM+M输入方式后,受试者回答问题时声音音量明显提高,表现更自信。结论:对于母语为声调型的汉语普通话人群,使用FM系统后能显著改善其在噪声环境的言语感知力,使其更接近正常听力人群。Objective： To evaluate the improvement of speech perception in Chinese-native cochlear implant （CI） children using frequency modulated system （FM system）. Method：The mandarin speech perception （MSP） system was used to evaluate 11 cases with severe and profound hearing loss who were fitted cochlear implants. Listeners were asked to repeat MSP words presented in quiet and several different signal-to-noise ratio （SNR） con- ditions and percent correct word repetition was determined. Performance was evaluated under FM system and without FM （CI only）. In addition, the listenersI subjective performance changes in the experiment were also ob- served. Result： 1There was significant main effect of the device condition （with FM and no-FM）（F= 72. 938, P〈 0.01）, a significant main effect of signal level （F= 230. 715, P〈 0.01）, a significant interaction effect between the signal level and the device condition （F= 40. 893, P〈0.01）. 2 Listeners answered the question in a louder voice, showed more confidence,when using with FM system. Conclusion： FM system could improve the speech re- ception in a complex environment for Chinese-native CI children.
