摘　　要：针对语音信号自身特点,利用Matlab仿真滤波器参数,设计滤波算法实现去噪功能。程序简单易行,通过TMS320C5402 DSP实验验证。并给出部分源程序,具有很强的实用性。According to the characteristics of the speech signals, a filter is designed with the pare meters simulated by Matlab to reduce the noises in the speech signals. The program designed with the parameters is simple and wieldy, and used in the TMS320C5402 DSP experiment. This design provide some resource program, and can be applied in many conditions.
