Joint Denoising and Dereverberation Using Exemplar-Based Sparse Representations and Decaying Norm Constraint

Exemplar-based nonnegative models, where the noisy speech is decomposed as a sparse nonnegative linear combination of the speech and noise exemplars stored in a dictionary, have been successfully used for speech denoising. This paper extends this …

Supervised Speech Dereverberation in Noisy Environments using Exemplar-based Sparse Representations

Exemplar-based techniques, where the noisy speech is decomposed as a linear combination of the speech and noise exemplars stored in a dictionary, have been successfully used for speech enhancement in noisy environments. This paper extends this …
