| Abstract(in English) | In this report, we propose a dereverberation method for speech enhancement microphone array system. The reverberation can be reduced by estimating the impulse response of acoustic path and then applying the inverse filter to the enhanced speech. However, the estimation error generates unpleasant noise where the acoustic path involves some non-minimum phase component. We reduce the unpleasant noise reduce by yielding the inverse filter with an adaptive filter based on MINT method. |
