1. A signal enhancement adaptive system, comprising: a speech model that characterizes statistical properties of speech; a noise model that characterizes statistical properties of noise; and, a plurality of adaptive filter parameters utilized by the signal enhancement adaptive system to provide an enhanced signal output, the enhanced signal output being based, at least in part, upon a plurality of frequency transformed input signals, the plurality of adaptive filter parameters being modified based, at least in part, upon the speech model, the noise model and the enhanced signal output.
