利用matlab软件提取共振峰参数利用matlab软件提取共振峰参数(Formant extraction can be used for voice recognition technology)

说明：  matlab语音识别算法，包括预处理，特征提取，训练，识别算法，基于hmm模型(Matlab speech recognition algorithms, including preprocessing, feature extraction, training, recognition algorithm based on model hmm)

基于压缩感知的语音信号的重构算法。使用的bp算法(Based on perception of speech signal compression algorithm of reconstruction. Using the bp algorithm )

本实例程序是基于matlab的语音识别程序，通过提取传统的MFCC特征集，采用当前流行的SVM分类器，作为对比实验是一个不错的选择。(This example program is popular SVM classifier matlab speech recognition program to extract MFCC feature set, as a comparative experiment is a good choice. )

一种加权K近邻语音情感识别程序，包括部分柏林语音情感库(A Weighting K-nearest neighbor speech emotion recognition program, including some libraries Berlin Speech Emotion)

自适应滤波器设计的matlab源程序，包括LMS,RLS,Kalman滤波等(Adaptive filter design matlab source code, including the LMS, RLS, Kalman filtering)

用c编写的文字转化成声音的程序,可以把该程序移植到单片机和其他嵌入式处理器中.实现应有的功能.(With c prepared text into sound procedures, the program can be transplanted into single-chip and other embedded processors. Realize the function.)

基于LMS算法和NLMS算法的自适应声回波消除器AEC，实现的主要功能是：在用户对电视发出的指令混杂了电视扬声器的声学回声的情况下，滤掉电视声音得到较为纯净的用户语音指令信号。(The main function of the adaptive filter based on the LMS algorithm and the NLMS algorithm is mixed: in the instruction issued by the user on the television TV speakers acoustic echo case, the TV sound was removed by filtration to obtain relatively pure user voice command signal.)

在提供音频的情况下，利用双音多频确定拨号音。(In the provision of audio cases, the use of dual-tone multi-frequency determine the dial tone.)

说明：  基于自适应子带频谱熵的稳健性语音端点检测(Based on adaptive sub-band spectral entropy of the robustness of Speech Endpoint Detection)
