Deep Recurrent NMF for Speech Separation by Unfolding Iterative Thresholding

1 code implementation21 Sep 2017 Scott Wisdom, Thomas Powers, James Pitton, Les Atlas

This interpretability also provides principled initializations that enable faster training and convergence to better solutions compared to conventional random initialization.

Enhancement and Recognition of Reverberant and Noisy Speech by Extending Its Coherence

no code implementations2 Sep 2015 Scott Wisdom, Thomas Powers, Les Atlas, James Pitton

Our approach centers around using a single-channel minimum mean-square error log-spectral amplitude (MMSE-LSA) estimator proposed by Habets, which scales coefficients in a time-frequency domain to suppress noise and reverberation.
