| Abstract: | A new scheme of speech endpoint detection based on information entropy was presented in this paper . We exploited the properties of the speech and the information entropy function, and constructed an entropy function adapted to speech signal processing. Experiments showed that the new scheme could obtain high scores on speech endpoint detection,and its complexity was very low . |
