In view of the problem that speech endpoint detection based on Empirical Mode Decomposition(EMD)loses its accuracy and adaptive in adverse environments, this paper proposes a novel speech endpoint detection algorithm based on EMD and cross-entropy. EMD decomposition characteristic is analyzed that probability distribution of white noise in each Intrinsic Mode Functions(IMF)is identified and unrelated to noise amplitude. Since probability distribution of white noise is different from that of speech signal, c...
