1. An apparatus, comprising: a speech processing engine having first and second forwardly independent audio speech paths, the first path being an audio perception path to be processed using a noise suppression technique and to be provided to an auditory receiver for reception by a user; and a Kalman filter coupled to the second path to receive an audio speech signal and to remove noise therefrom, the Kalman filter to remove said noise based at least in part on a speaker model input including speaker glottal information, in which the speaker model incorporates previously generated noise-removed speech signal information for the speaker; wherein the Kalman filter is to linearly add each of a specified glottal pulse variable and a specified environmental noise variable to a product of a current clean speech vector variable and a state transition matrix variable.

The apparatus of claim 1 , in which the filter is to remove noise based also on a noise model input including environmental noise information.
