Abstract

The present embodiments provide speech enhancement based on source separation techniques. Specifically, we use a universal spectral model for speech, and train the spectral model for noise and activations for speech/noise based on the universal spectral model for speech and input noisy speech. We formulate the optimization problem using a cost function that includes a divergence function and a sparsity penalty function, wherein the penalty function is based on the notion of relative group sparsity. The sparsity penalty function includes two parts: a sparsity-promoting part for the groups (activations for some groups become zero) and an anti-sparsity-promoting part for the whole activation matrix corresponding to the speech model (i.e., the activations for speech as a whole does not become zero). Based on the universal spectral model for speech, the spectral model for noise, and activations for speech/noise, we can estimate the speech/noise included in the input noisy speech.
