基于听觉模型反演方法的语音信号分析及应用

本文在吸收听觉生理学研究成果基础上，建立了一个模拟外围听觉系统和部分中枢神经系统功能的听觉模型。该模型作为前端处理来提取语音信号的自相关图谱，并且通过听觉模型的反演实现了从信号的自相关图谱中重构原始的语音信号。实验结果表明，通过听觉模型反演从信号的自相关图谱中恢复出的语音信号，具有较好的自然度和良好的噪声鲁棒性。

Speech signals''''s analysis and application Based On the auditory model inversion

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. With the auditory model as the front-end to extract the correlogram of signals. Following, resynthesize original signal from the correlogram by the implementation of suditory model inversion. The result of experiments show that resynthesized speech signals form the its correlogram by auditory model inversion is nature and robust in noisy environment.
