摘　　要：在生活中,要使语音更加清晰,最主要就是消除噪声,而消除噪声则要确定噪声段的位置,因此分段语音与噪声段成了很首要的一点。在研究领域里,根据语音特有参数可以确定该段是否是非噪声段。将语音信号和噪声信号按一定的信噪比混合,得出带噪语音中语音段的起点和终点。利用Matlab进行试验仿真,最终成功的区分噪音段和语音段。In daily life,to make speech clearer,the most important thing is to eliminate noise,and to eliminate noise,it is necessary to determine the position of the noise segment.Therefore,segmenting speech and noise segments has become a very important point.In the research field,it is possible to determine whether a segment is a non noisy segment based on speech specific parameters.Mix speech signals and noise signals at a certain signal-to-noise ratio to obtain the starting and ending points of speech segments in noisy speech.Using Matlab for experimental simulation,the noise and speech segments were successfully distinguished.
