| Abstract: | The endpoint detection which influences the speed and results of speech signals processing directly is a important step for speech signal processing. In this paper, a new speech endpoint detection method based on ICA(Independent Component Analysis) enhancement and spectral entropy is proposed. The simulating results show that the proposed method can detect the endpoint exactly in the low SNR environments. |

| Keywords: | independent component analysis spectral entropy endpoint detection |
