本论文首先简要概述语音信号,通过引入语音信号的初步知识，比如语音信号的接收与感知等等,再分别对时域的短时能量,短时平均过零率,端点检测,短时自相关函数等参数进行研究，以及频域的短时傅立叶的研究,通过这两方面的优点和缺点,进一步对语音信号的时频方面等Gabor变换,小波变换等参数进行研究.
在此理论的基础上,用matlab进行语音信号的仿真,通过观察波形的变化.从而更直观的分析各参数的意义.
The processing method is studied frequently when pronunciation signal, its basic thought is a union function of designing time and frequency, describe the pronunciation signal is in different time and energy density and intensity of the frequency with it.
This thesis sums up the pronunciation signal briefly at first, through introducing the preliminary knowledge of the pronunciation signal, for example pronunciation signal receive and perceive, correct time energy in short-term of the land respectively and then, a over a rate on average in short-term, the extreme point is measured, parameters such as the auto-correlation function,etc. carry on research in short-term, and research to set up leaf Fu in short-term of land frequently, pass two of advantages and disadvantages these, respect wait for Gabor vary frequently when signal to pronunciation further, small wave vary parameter goes on research.
On the basis of this theory, carry on the emulation of the pronunciation sig
