plv_measure
- this function computes phase synchronization using Phase locking value method over an analysis window of fixed length inputs to this function - phase, sampling frequency output this function - synchronization measure based on PLV processing perform
EWT
- 经验小波变换结合EMD的自适应性和小波分析的理论框架,Gilles提出了一种称为经验小波变换(EWT)的自适应信号处理方法.其核心思想是通过对信号的Fourier谱进行自适应划分,建立合适的小波滤波器组来提取信号不同的AM-FM成分.-Empirical wavelet transform
DSP
- DSP实现基于LPC的语音基频提取算法，包含采样、fir滤波器，LPC算法等的编写 -The realization of the speech pitch extraction algorithm based on LPC
Extract-Sound-Feature
- 利用matlab提取声音的基本特征，包络、MFCC、声谱图、能量。代码不复杂，但是省去大家找这些的时间。-The basic feature extraction using matlab sound envelope, MFCC, sonograms, energy. Code is not complicated, but we look for these omitted time.
VolumeControl
- Vb音量控制源码，麦克风音量调整，值得收藏的源码程序-Vb volume control source, microphone volume adjustment, it is worth collecting the source program
CZTtransformer
- CZT运算是在z域以任意螺线采样，源码采用512点做CZT运算求出频域最大值-CZT operation is in the Z domain to arbitrary spiral sampling, the source code using 512 points to do CZT operations to calculate the maximum frequency
G.729a-gst
- G.729a位取反,信噪比测试代码。MFC编写的,测试可用。-G.729a bit inversion, signal to noise ratio test code
HMM-master
- This code is to integrate HMM and HTK
Voice-endpoint-detection
- 语音识别检测端点也就是采集声音信号的时候，开始说话到说话结束，我们把这一段声音信号采集下来进行处理。不然那么多信号都去处理，没有声音也处理那就浪费了很多的空间以及浪费了CPU去做后续的操作。这是一段语音识别检测端点代码。-Speech recognition detection endpoint is to collect the sound signal, began to speak to the end of the speech, we put this section of the s
matlab
- 寻找峰值的函数，基频的检测，帧数的计算问题以及加噪声-Find the function of the peak, the detection of the fundamental frequency, the calculation of the number of frames and the addition of noise
ISM
- 房间脉冲响应函数IMAGE,用于计算房间混响时间的-Room impulse response function IMAGE, used to calculate the room reverberation time
yuyinshibie
- 基于MATLAB的语音识别。内容比较全，比较适合初学者进行学习，主要包含了一些基础的mfcc等的算法，可以直接的调用-MATLAB based speech recognition. The contents of the whole comparison, more suitable for beginners to learn, including some of the basic MFCC algorithm, you can directly call
