1. A computer-implemented method, executed on a computing device, comprising:
obtaining one or more speech signals from a first device, thus defining one or more first device speech signals;
obtaining one or more speech signals from a second device, thus defining one or more second device speech signals;
selecting a noise component model from a plurality of noise component models based upon, at least in part, the one or more first device speech signals and the one or more second device speech signals, wherein the noise component model maps noise spectrum of the first device speech signals to the second device speech signals; and
augmenting, at run-time, the one or more second device speech signals based upon, at least in part, the noise component model.
