语音信号预滤波的几种仿真实现方法

Several Simulation Methods of Speech Signal Pre-filtering

滤波器设计是数字信号处理的主要内容,用滤波器对语音信号进行预滤波是比较经典的一种方法。文章详细介绍了用滤波法对语音信号进行预滤波的几种典型的仿真实现方法,主要包括在Matlab环境中语音信号预滤波的仿真实现,在SystemView中语音信号预滤波的设计实现,以及在CCS集成开发环境下,用C54x Simulator模拟在TMS320VC54x DSP上进行的语音信号预滤波的实现等。

Filter design is an important part of digital signal process.It is a classical method to suppress speech signal noise by filtering.This paper introduces several typical simulation methods to suppress speech signal noise by filtering in detail.The first method to design the speech signal noise suppressing system is by Matlab.The second method of designing the noise suppressing system is by SystemView.The last method but not list is operated in CCS(Code Composer Studio) integrative exploiting condition.C54x S...
