Abstract :
A novel technique is presented, based on linear prediction coding (LPC) analysis, which enhances the estimate of the frequency response of unobservable linear time-invariant (LTI) systems characterised by an all-pole transfer function. The technique is particularly applicable to spectrally based feature extraction from the speech signal.
