用VC实现的语音库的建立的程序. 首先建立单音节语音库,然后将所有的单音节语音文件合成一个大的.wav文件,并且制定索引机制,便于快捷查找...

指纹识别的程序(c++)-Fingerprint Recognition Procedure (c)

利用HMM的孤立字(词)语音识别程序,谢谢大家关注-A program of Using HMM s insulation word to recognise speech signal. Thank you for attention

语音识别中的两种特征提取方法lpcc和mfcc，还有一个是文本无关的识别算法dtw，另外还有一个是预处理消噪部分的。共享一下，这些都是我调试过的，好用。-Speech Recognition two feature extraction methods and mfcc lpcc. There is a text-independent recognition algorithm dtw, in addition to a pretreatment is part of the noise source. Sharing that those are off the debugging and ease of use.

语音降噪的M程序，原信号加噪声，进行滤波得出原始信号-M procedures, the original signal plus noise, obtained the original signal filtering

语音识别中提取特征向量和进行特征向量比对的DTW源代码-Speech Recognition feature extraction and feature vectors to the right than the source code DTW

时域波形、短时能量、短时平均幅度、短时过零率、短时过电平率-Time-domain waveform, short-term energy, short-term average rate, short-term zero crossing rate, short-term rates over Level

老师布置的一个project，里面有题目和源程序，能够识别十个数字。-This is a project given by teacher ,including subject and code .It can recognise ten numbers.

This code is used to remove silence from a voice signal so that the recognition in voice recognition will give good result. The method is Scale on threshold applied to the envelope for detecting scilence periods. The actual threshold is computed by multiplying threshin" by the median value of the envelope samples. The default is (.25), whichis 25 of the median envelope value over input signal .-This code is used to remove silence from a voice signal so that the recognition in voice recognition will give good result.
