摘要：
Based on the human auditory perceptual properties, a new method for speech detection was proposed. The new method consists of the classical RASTA-PLP filter in logarithmic power spectrum domain and a differential filter in time domain. In this manner, all kinds of noise can be removed efficiently. Proved by experiments, which mass data of these experiments come from original real recording of wireless communication on spot, this method can detect speech stream efficiently and the new method outperforms the conventional detection method.
