语音信号的预加重处理，利用MATLAB编程，取得了不错的效果-Voice signal pre-emphasis processing, the use of MATLAB programming, and achieved good results

本文根据孤立词语音识别系统的处理步骤，从语音信号的预处理开始，分别详细说明了每个过程，比如预加重、分帧加窗和端点检测。接着介绍了特征参数MFCC的原理与选取，最后介绍了DTW算法的特点-In this paper, based on the process steps of isolated words speech recognition technology, starting with the speech signal pre-processing, each process is

对信号进行梅尔倒谱系数特征采集之前的预处理，包括分帧加窗、基于短时能量的双门限判别、除噪、预加重等(The preprocessing of Mel cepstrum coefficients before the signal is carried out, including frame windowing, double threshold discrimination based on short-time energy, denoising and pre emphasis)
