凌阳SPCE06的语音通信代码,利用了双缓冲队列,是学习的好例子,希望很大家一起分享(Sunplus SPCE06 voice communications code, the use of the double-buffer queue, is a good example of learning, hope to share with everyone)

hmm 说话人识别 matlab 算法，c++算法，(speaker recognition hmm)

绘制语音信号的 WVD 分布，对时频工具箱中的 tfrwv 及 tfrspwv 函数的使用进行了详细说明(The way of drawing speech signals WVD was shown in the m file, and corresponding functions tfrwv and tfrspwv were discussed thoroughly.)

1.进行含噪语音信号的时频分析 2.设计合适滤波器进行去噪 3.进行去噪后信号的时频分析4.设计一个混响器（用四个梳状滤波器和两个全通滤波器（下图所示））来产生回声（通过一个均衡器(Reverberation)

回声消除算法比较，仿射投影APA与NLMS算法比较(Echo cancellation apa nlms)

语音识别，dtw算法，matlab程序 语音识别，dtw算法，matlab程序(Speech recognition, dtw algorithm, matlab program speech recognition, dtw algorithm, matlab program)

本次课程设计主要介绍了语音信号的录制、语音信号的采集与分析、语音信号的采样、语音信号的频谱分析、加噪后的频谱分析、滤波器的设计以及对于语音信号的回放等知识。通过 Cool Edit录制一段语音信号，运用MATLAB对其进行时域与频域分析，然后设计滤波器加入噪声进行滤波处理，比较滤波前后始于波形或频谱的变化，最后实现对于语音的回放设计。(Digital voice processing filter design)

mfcc特征提取法 以及svm训练 可以使用(MFCC feature extraction method and SVM training can be used)

网页校验码识别程序，识别网上数字校验码，准确性高。(website check code identification procedures, and identification number of online check codes and high accuracy.)

ARMA模型建立程序，给出自相关序列，指定ARMA模型的P阶，Q阶参数，得出相应的参数值 function [bq ,ap]=armahat(rx,p,q)(ARMA model for the establishment of procedures, to come from related sequences, designated the P-order ARMA model, Q-order parameters, the corresponding parameter values derived function [bq, ap] = armahat (rx, p, q))
