  • Mathematical morphological filtering is a nonlinear transform to operate on shape of the signal,which can simplify the signal and eliminate some small components of the signalwithout corrupting shape of the signal.In this paper,two schemes extracting pitch of speechsignal using mathematical morphological filtering are proposed,which are quite simple,compu-tationally very efficient,and apt to be implemented by hardware.Experimental results show that more precise pitch,as compared with conventional methods,will be obtained if appropriate parameters are selected.
