一种改进的基于倒谱距离端点检测方法研究
A Modified Method of Endpoint Detection with Cepstrum Distance
摘要
Abstract
Based on the imperfect discussion of the traditional speech endpoint detection method of cepstrum distance,an improved method is proposed.By analyzing the three endpoint detection of speech signal,including the characteristic parameters of short-time energy,short time zero rate on average and cepstrum distance,a combination of the three features is proposed,applied to the endpoint detection.The experimental results show that compared to the basic cepstrum distance detection method,this method is obviously improved in low signal-to-noise ratio detection performance.关键词
