Signal-Based Performance Evaluation of Dereverberation Algorithms

open access: yesJournal of Electrical and Computer Engineering, 2010
We address the measurement of reverberation in terms of the (DRR) in the context of the assessment of dereverberation algorithms for which we wish to quantify the level of reverberation before and after processing. The DRR is normally calculated from the

Deep Learning-Based Amplitude Fusion for Speech Dereverberation

open access: yesDiscrete Dynamics in Nature and Society, 2020
Mapping and masking are two important speech enhancement methods based on deep learning that aim to recover the original clean speech from corrupted speech. In practice, too large recovery errors severely restrict the improvement in speech quality.

Multimicrophone Speech Dereverberation: Experimental Validation

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2007
Dereverberation is required in various speech processing applications such as handsfree telephony and voice-controlled systems, especially when signals are applied that are recorded in a moderately or highly reverberant environment.

Subspace Methods for Multimicrophone Speech Dereverberation [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
A novel approach for multimicrophone speech dereverberation is presented. The method is based on the construction of the null subspace of the data matrix in the presence of colored noise, using the generalized singular-value decomposition (GSVD ...

On the importance of power compression and phase estimation in monaural speech dereverberation [PDF]

open access: yesJASA Express Letters, 2021
Previous studies have shown the importance of introducing power compression on both feature and target when only the magnitude is considered in the dereverberation task.

Effective Dereverberation with a Lower Complexity at Presence of the Noise

open access: yesApplied Sciences, 2022
Adaptive beamforming and deconvolution techniques have shown effectiveness for reducing noise and reverberation. The minimum variance distortionless response (MVDR) beamformer is the most widely used for adaptive beamforming, whereas multichannel linear ...

Jointly Optimal Dereverberation and Beamforming [PDF]

open access: yesICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020
We previously proposed an optimal (in the maximum likelihood sense) convolutional beamformer that can perform simultaneous denoising and dereverberation, and showed its superiority over the widely used cascade of a WPE dereverberation filter and a conventional MPDR beamformer.

A neural network-supported two-stage algorithm for lightweight dereverberation on hearing devices

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2023
A two-stage lightweight online dereverberation algorithm for hearing devices is presented in this paper. The approach combines a multi-channel multi-frame linear filter with a single-channel single-frame post-filter.

pykanto: A python library to accelerate research on wild bird song

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 8, Page 1994-2002, August 2023., 2023
Abstract Studying the vocalisations of wild animals can be a challenge due to the limitations of traditional computational methods, which often are time‐consuming and lack reproducibility. Here, I present pykanto, a new software package that provides a set of tools to build, manage, and explore large sound databases.

Head‐related transfer function–reserved time‐frequency masking for robust binaural sound source localization

open access: yesCAAI Transactions on Intelligence Technology, Volume 7, Issue 1, Page 26-33, March 2022., 2022
Abstract Various time‐frequency (T‐F) masks are being applied to sound source localization tasks. Moreover, deep learning has dramatically advanced T‐F mask estimation. However, existing masks are usually designed for speech separation tasks and are suitable only for single‐channel signals.
