Trade-off evaluation for speech enhancement algorithms with respect to the a priori SNR estimation acoustics
In this paper, a modified a priori SNR estimator is proposed for speech enhancement. The well-known decision-directed (DD) approach is modified by matching each gain function with the noisy speech spectrum at current frame rather than the previous one. The proposed algorithm eliminates the speech tr...
