An overview of some key issues involved in single-channel blind dereverberation is presented, beginning with a discussion on the nature of time-varying acoustic channels, the problem of long acoustic impulse responses and an introduction to model-based solutions. The paper then discusses an approach in which the acoustic source is modelled by a time-varying AR process, and the channel by a linear time-varying all-pole filter. In each case, the time-varying filter coefficients are modelled as a…

Blind dereverberation of speech from moving and stationary speakers using sequential Monte Carlo methods
Speech signals radiated in confined spaces are subject to reverberation due to reflections of surrounding walls and obstacles. Reverberation leads to severe degradation of speech intelligibility and

TLDR
Although the emphasis of the proposal is the scalability of the model, preliminary results are presented for the case when real speech is passed through a synthetic channel, with the aim of tackling real room acoustics.
Equalization in an acoustic reverberant environment: robustness results
TLDR
It is shown that due to the variations of the transfer function from point to point in a room, even small changes in the source or microphone position can cause large degradations in the equalized room response.
Nonminimum-phase equalization and its subjective importance in room acoustics
TLDR
An alternative approach to the minimum-phase/all-pass decomposition based on iterative flattening of the room transfer function (RTF) magnitude is presented, which overcomes potential numerical problems and provides more insight into subjective aspects of magnitude and phase equalization in the reduction of acoustic reverberation.
Blind single channel deconvolution using nonstationary signal processing
TLDR
The proposed Bayesian method does take account for the channel's stationarity in the model and is more robust, and the advantage of utilizing the nonstationarity of a system rather than considering it as a curse is discussed.
