In this paper , on the basis of absorption of achievements of the research on auditory physiology , an auditory model simulationg the peripheral auditory system and part of the central auditory system is set up . the model is made of the fitlters presenting the characteristics of the basilar membrane for analyzing the voice signals , the half wave rectification modeling the inner hair cells and energy transfer of nerve fiber 在吸收聽覺生理學研究成果基礎上,建立了一個模擬外圍聽覺系統(tǒng)和部分中樞圣經(jīng)系統(tǒng)功能的聽覺模型。模型由表征基底膜的頻率分析的帶通濾波器組、內(nèi)毛細胞的半波整流特性和神經(jīng)纖維的能量轉(zhuǎn)換特性組成,該模型可以作為前端處理來提取語音信號的自相關圖譜。
