电子耳蜗CIS语音信号处理方案的计算机仿真及声音合成

Computer\|Based Acoustic Simulation of CIS Speech Processing Strategy for Electronic Cochlear Implants

电子耳蜗是用有限个电极刺激听神经以恢复全聋人听觉的装置。本文利用耳蜗的电刺激简化模型， 在计算机上对连续交替取样 （ｃｏｎｔｉｎｕｅｄ ｉｎｔｅｒｌｅａｖｅｄ ｓａｍ ｐｌｉｎｇ， 简称ＣＩＳ） 方案进行了仿真及声音合成， 以模拟耳蜗植入者感受到的声音。仿真方法和结果对研究语音信号处理的新方案及临床参数选择具有一定的意义。

Electronic cochlear implant is an electronic device to restore profoundly deaf people's hearing with limi ted electrodes implanted in their cochleae.The objective of this study is to develop a computer\|based acoustic simulation method to simulate actual sound perception by the deaf fitted with cochlear implants.In this paper,the acoustic simulation of CIS processors by using simplified cochlea model of electrical stimulation and simulation results on Chinese speech are discussed.\;
