Fig. 6From: Speech enhancement by LSTM-based noise suppression followed by CNN-based speech restorationSpectrograms of reference and enhanced speech for a male speaker in unseen pub noise at 5 dB SNR. From top to bottom: clean speech, noisy speech, LSTM-MSA, LSTM-cMSA, new LSTM-cMSA+DNN-cSA, proposed LSTM-cMSA+CED-cSA-tr, and high-complexity reference LSTM-cMSA+CLED-cSA-duBack to article page
