| Abstract(in English) | We propose a new noise suppression method, which is an extention of optimally-modified log-spectrum amplitude (OM-LSA) noise suppression with the bi-directional processing on the time axis. We also show the evaluation results which confirm the effectiveness of the proposed method. The proposed method works better than standard OM-LSA in the case where the estimation error of OM-LSA accumulates over time. A simple look-ahead mechanism is also implemented in each uni-directional estimation, and makes the estimation more robust. The evaluation experiments are carried out using our proprietary database and CENSREC-2, and the results approved the effectiveness of the proposed method. |
