the overlapped speech is defined as the hybrid of two or more original speeches.Because there is not any direction information

it is more difficult to segregate the overlapped speech.But the human auditory system can successfully perceive and segregate this kind of overlapped speech.This paper addresses the problem of the overlapped speech segregation based on the speech harmonicity.A frame synchronized segregation method based on harmonic analysis is proposed and some corresponding experimental results are given.
