speech recognition matlab code

matlab信号处理详解,各种信号的产生，滤波器的设计，以及许多Matlab源程序(signal processing matlab explain, the emergence of a variety of signals, filter design, as well as many Matlab source code)

说明：  通信信号的调制信息包含在信号的瞬时幅度、相位、频率的变化之中，不同的信号其频谱也呈现不同的特征，通过提取瞬时幅度、相位、频率以及频谱的参数统计特征，可以识别不同的通信信号。通常是利用对瞬时幅度、瞬时相位，瞬时频率和信号功率谱进行某种变换而得到可以明显区分各种信号的特征参数。(Communication signal modulation information is contained in the signal instantaneous amplitude, phase, frequency changes, the spectrum of different signals also show different characteristics, by extracting the instantaneous amplitude, phase, frequency and statistical characteristics of the parameters of the spectrum, you can identify different communication signals. Usually by the use of instantaneous amplitude, instantaneous phase, instantaneous frequency and signal power spectrum a transformation which can be clearly distinguished by the characteristic parameters of various signals.)

past-music算法，用来进行谐波分量的求解。速度快，效果佳(past-music algorithm used for solving the harmonic components. Fast, good effect)

1、 从网上下载人脸图像，构建人脸训练数据库和测试数据库，采用K-L变换进行特征脸提取，并实现人脸识别。通过K-L变换在人脸识别中的应用，加深对所学内容的理解和感性认识。(1, face image downloaded from the Internet, the construction of the training and test database face database, using K-L transform features face extraction, and realize the face recognition. Through k-l transform in face recognition application, deepen the understanding of the content of study and perceptual knowledge.)

基于matlab的直接序列扩频信号的产生与捕获模拟(Direct sequence spread spectrum signal generation and capture analog)

这是本人编写的一个利用维纳滤波实现语音增强的程序.在输入语音信噪比不是很低的情况下,效果不错.(This is one I prepared realize the use of Wiener filter speech enhancement procedure. In the input voice signal to noise ratio is not very low circumstances, good results.)
