使用Labview使用matlabscr ipt节点调用五点图像预处理法，其中部分matlab函数无法在labview中运行就自己用vi代替了-Use matlabscr ipt node using Labview call five-point image preprocessing method, some of which can not be in the labview matlab function to run on their own instead of using vi

基于matlab采集语音信号；实现语音预加重、过零检测、分帧等预处理；实现可视化界面设计，完成语音预处理过程显示；-Matlab based speech signal acquisition, voice pre emphasis, zero detection, sub frame, etc. preprocessing visual interface design, complete voice preprocessing process display
