Single-channel speech enhancement based on joint constrained dictionary learning

Abstract: To improve the performance of speech enhancement in a complex noise environment, a joint constrained dictionary learning method for single-channel speech enhancement is proposed, which solves the “cross projection” problem of signals in the joint dictionary. In the method, the new optimization function not only constrains the sparse representation of the noisy signal in the joint dictionary, and controls the projection error of the speech signal and noise signal on the corresponding sub-dictionary, but also mi… Show more

“…In addition, in [27], the authors proposed a statistical speech enhancement model using acoustic environment classification supported by a Gaussian mixture model. In [28], the authors proposed a joint-constrained dictionary learning method to solve the "cross projection" problem of signals in the joint dictionary for single-channel speech enhancement.…”

“…The above classical algorithm performs well in stationary noise, but is weak in dealing with non-stationary noise [7]. Speech enhancement algorithm using speech and noise prior information; Including hidden Markov model method [8], non-negative matrix decomposition [9][10], dictionary learning [11][12][13], etc., the effect of dealing with non-stationary noise is obviously better than that of classical methods without prior knowledge [14].…”
