A Multichannel Speech Dereverberation Technique Based Upon the Wiener Filter
We present a new method for dereverberating speech, based upon a multichannel Wiener Filter and a microphone array. We demonstrate the effectiveness of this method under real, reverberant conditions and show that the method may be described as a self-steering beamformer. Furthermore, we investigate the performance of the method under simulated conditions, designed to closely match the acoustic characteristics of the real room environment. These simulations yield significantly inferior results to those obtained using real recordings and we show that this is as a result of the failure of simulated impulse responses to accurately model real impulse responses, in certain critical respects.
