G.711 voice codec to achieve the CCS source code

基于ipp的信号处理代码，几乎包含了处理各种算法。 需要IPP库支持。-based on the signal processing code, contain virtually processing algorithms. Need the support of IPP.

自己编写的用于传感器信号滤波的算法程序，并有真实信号处理的数据演示-I have written for the sensor signal filtering algorithms procedures and have the authentic signal processing of data presentation

本程序包含语音压缩和语音识别领域所需的LPCC，MFCC特征提取算法以及语音端点检测源码。-This procedure includes voice compression and voice recognition requirements in the area of the LPCC, MFCC feature extraction algorithm, as well as voice activity detection source.

首先对语音信号的预处理和特征提取问题进行了讨论,提取了三个有效的语音识别特征参数—LPC系数、LPC倒谱系数和Mel频率倒谱系数(MFCC);其次着熏讨论了语音识别中常用的两种识别方法—基于模板匹配的DTW和基于统计膜型的HMM在语音识别中的应用,分别讨论了各自的模型训练和识别的方 法,对HMM在实际应用中的一些具体问题也进行了讨论;最后对常规HMM提出了一些改进方法,包括显式状态驻留和随机分段模型(SM),重点讨论了SM在 语音识别中的训练和识别方法,并通过一个孤立数字语音识别系统验证了其比常规HMM更能描述语音信号的特征。
