摘　　要：随着数字信号处理技术的发展,语音信号采集与处理系统的设计也受到了研究人员的广泛关注。数字信号处理技术的发展,是的对于数字语音的处理充满了灵活性。本文着重研究利用Matlab软件采集语音信号,并采用多种降噪方法对采集到的语音信号进行去噪处理,由于人们对于跟人隐私越来越注重,因此本文还提出了一种对于语音的加密解密方法,从而实现了对于个人因此的保护。With the development of digital signal processing technology,the design of voice signal acquisition and processing system also received extensive attention of the researchers.The development of digital signal processing technology,is full of flexibi lity for the processing of digital voice.This paper focuses on using the Matlab software acquisition speech signal,and many kinds of noise reduction method to deal with the noise of speech signals,because people pay more and more attention to privacy,this paper also proposes a voice encryption decryption method,so as to realize the protection for individual privacy.
