Abstract
A new algorithm for end-point detection in noisy background conditions based on the statistical properties of higher-order cumulants of speech signal is presented in this paper. Since the higher-order cumulants are blind for Gaussian signal, the proposed method is especially effective to the problem of end-point detection of speech signals in Gaussian noise. The above conclusions are supported by the experimental results.
