自己做的一个支持向量机分类程序,调试过是可以用的(Do one SVM program , debugging can be used )

matlab教材中经典的语音增强算法，voice enhancement 先读入语音文件，然后计算前后信噪比，最后画出波形。(The classic textbook matlab speech enhancement algorithms, voice enhancement before reading the speech file, and then calculate the signal to noise ratio before and after the final draw waveforms. )

它是基于matlab的语音分帧的代码，相信对大家理解有帮助。(It is based on the matlab voice sub-frames of the code, I believe we understand help.)

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.)
