Research on Speech Endpoint Detection Algorithm Based on Matlab
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.
