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.
Abstract
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,seg-menting 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 parame-ters.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 simula-tion,the noise and speech segments were successfully distinguished.
