Towards single-channel blind dereverberation of speech from a moving speaker

  title={Towards single-channel blind dereverberation of speech from a moving speaker},
  author={James R. Hopgood and Christine Evers},
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

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
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
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
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.

This paper presents a Bayesian approach for blind source recovery based on Rao-Blackwellised particle filtering techniques. The proposed state space model uses a time-varying autoregressive (TVAR)
The Excess Phase in Loudspeaker/Room Transfer Functions: Can It Be Ignored in Equalization Tasks?
The impulse response c[n] characterizing the system of a loudspeaker and a microphone placed in a closed room contains information on the electroacoustical properties of loudspeaker and microphone as
Parameter estimation of time-varying autoregressive models using the Gibbs sampler
A method is described for applying a Markov chain Monte Carlo method known as the Gibbs sampler to the problem of estimating the parameters of a flexible time-varying autoregressive (TVAR) model with
