摘要

基于MATLAB设计了一个支持单、双声道的语音信号处理系统，可实现语音信号的分析、加噪及窗函数滤波。针对语音信号中所添加的不同频段的噪声，可自主地选择合适的窗函数完成噪声滤波，并进行各种滤波效果的对比。实验表明：该系统界面友好、操作简单，便于直观了解语音信号和滤波器特性，可用于作教学演示等。 A GUI for signal procession system for single-way or two-way sounds is presented, based on MATLAB, where various operations can be carried out such as analysing sound signals, adding noise, filtering by window function method. On account of the noise at different frequencies added to the original sound signal, applicable window function can be utilized to complete filtration independently. This experiment manifests that it is convenient to understand sound signals and filter’s characteristics on this GUI, because of its simplified procedures and friendly interface, which makes this GUI perfect for teaching use.
