Abstract
The minimum-phase components of source waveforms can be recovered by blind dereverberation using the minimum-phase complex cepstrum. This recovery process is robust for changes in the transfer functions (TFs), since the all-pass components of the responses that are highly sensitive to changes in the TFs can be disregarded. Yet it is still necessary to keep all-pass information if the timing of the source event is required. Dereverberation of reverberant speech signals requires the all-pass components to keep the pitch information.Keywords
