ABSTRACT:
A method of estimating the pitch of a speech acoustic signal in a time interval in which said signal is a voiced one, wherein the pitch corresponds to the distance between the contact points of a circle and a plot, normalized to a limit value, of the energy of said speech acoustic signal as a function of time; said contact points being obtained by rolling said circle on said plot.
