Single channel reverberation suppression based on sparse linear prediction [PDF]
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014 Reverberation degrades speech intelligibility in telecommunications as well as it increases the word error rate in automatic speech recognition tasks. Several dereverberation methods have been proposed recently in order to counter these effects. In the single microphone case, the dereverberation problem is underdetermined and reverberation suppression ...

Binaural speech intelligibility for combinations of noise, reverberation, and hearing-aid signal processing. [PDF]
PLoS ONEBinaural speech intelligibility in rooms is a complex process that is affected by many factors including room acoustics, hearing loss, and hearing aid (HA) signal processing. Intelligibility is evaluated in this paper for a simulated room combined with a

Optimized gain functions in ideal time-frequency masks and their application to dereverberation for cochlear implants [PDF]
JASA Express Letters, 2021 The present study investigated three different reverberation suppression rules based on the parametric ideal ratio mask, which is a generalization of the classical Wiener filter with additional parameters controlling the threshold and slope.

A signal enhancement method based on the reverberation statistical information
EURASIP Journal on Advances in Signal Processing, 2022 This paper proposes a reverberation suppression algorithm utilizing fractional lower-order moments based on statistical properties. As fractional lower-order moments can only be applied on symmetric α-stable random variables, the energy redistribution ...
