语音识别是近年来发展非常迅速的一项计算机智能技术，广泛应用在语音控制、身份识别等多个领域。本次项目主要研究语音识别的预处理过程和特征参数的提取环节。通过对原始语音信号进行预加重和分帧、加窗，滤除低频干扰，提升对语音识别有用的部分，消除了部分噪音和失真。预处理之后进行信号的特征提取，主要选取了短时平均过零率和MFCC两个特征参数，应用matlab软件绘制波形图并提取特征参数矩阵，为之后的语音信号的识别打下了基础。(Speech recognition is a computer intelligent technology which has developed rapidly in recent years. It is widely used in speech control, identity recognition and other fields. This project mainly studies the pretreatment of speech recognition and the extraction of feature parameters. Through pre-emphasis, framing and windowing of the original speech signal, the low frequency interference is filtered out, the useful part of speech recognition is enhanced, and some noise and distortion are eliminated. After pretreatment, feature extraction of signal is carried out. Two feature parameters, short-term average zero-crossing rate and MFCC, are selected. Waveform diagram is drawn by MATLAB software and feature parameter matrix is extracted, which lays a foundation for speech signal recognition.)

对滤波器耦合矩阵中的极点和零点位置进行编程，以求出表示零点极点的多项式(Coupling matrix of the filter pole and zero position programming has been calculated F (w) E (w) polynomial)

随机森林，matlab程序编写，用于分类和回归(Random Forests, matlab programming for classification and regression)

这个程序可以自定义颜色选择框，因为matlab自带的uisetcolor在编译后的.exe中运行会导致窗口最小化，所以可以自定义颜色选择框(This procedure can customize the color selection box, because in uisetcolor built-in matlab compiled. Exe run will lead to minimized windows, so can customize the color selection box)
