Abstract:The endpoint detection is an essential technology in a speech recognition system, its accuracy has a very tremendous influence on the speech recognition performance. The paper makes researches and improvements to the traditional algorithm for speech signal endpoint detection, and the exeperiment indicates that good detection performance can be obtained in the low SN1L. With the development of the speech recognition technology, this algorithm will be compicious for its high efficiency, synchronic and accuracy in the application use,
Keywords:speech signal  endpoint detection  lineer predictive coding  reel frequency coding coefficient  cepstral characteristic
