| 摘 要： | 语音信号是一种非线性时变的信号，因此在传输和存储过程中，很容易受到外界环境的干扰，最主要的是高斯白噪声的干扰。本文针对语音信号的噪声特点，提出在非特定环境下去除噪声的方法。仿真结果表明，在信噪比为63 dB的情况下，还原的语音信号能够满足我们人耳的要求，体现了该方法的一般性和可行性。

| Abstract: | The speech signal is a nonlinear time -varying signal ,therefore in the process of transmission and storage ,it is easy to be interfered with the external environment ,the most important is the Gauss w hite noise .In this paper ,according to the noise features of speech signals ,the method of removing noise in non specific environment is put forward .The simulation results show that ,when SNR is 63 dB ,the speech signal reduction can meet our ear requirements and reflect the general feasibility and the method . |
