1. A system that facilitates enhancement of a speech signal comprising: an input component that receives a speech signal and pixel-based image data relating to an originator of the speech signal; and, a speech enhancement component that employs a probabilistic-based model that correlates between the speech signal and the image data so as to facilitate discrimination of noise from the speech signal, the model employing a set of hidden variables representing relevant features, the features being inferred from at least one of the speech signal and pixel-based image data.
