Speech intelligibility is enhanced by extracting active speech frames from an input S101, calculating a measure of the frame importance S102 (based on eg. Mel cepstral coefficients indicating dissimilarity to the previous frame), and modifying the frames S106 (by eg. overlap-add, fig. 7) based on their importance and an estimation of a contribution due to late reverberation S103 (eg. assuming a long-trained decaying impulse response). Frame power may also be computed and modified (fig. 8). |
