Speech Dereverberation [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1973
A method for dereverberating speech based on linear prediction is developed in detail. By properly analyzing and resynthesizing speech that has been reverberated by a real room, it is possible to remove most of the reverberation. The algorithm will be described and tapes will be played.

Noise Robust Blind System Identification Algorithms Based On A Rayleigh Quotient Cost Function [PDF]

open access: yes, 2015
An important prerequisite for acoustic multi-channel equalization for speech dereverberation involves the identification of the acoustic channels between the source and the microphones. Blind System Identification (BSI) algorithms based on cross-relation

A reverberation-time-aware DNN approach leveraging spatial information for microphone array dereverberation

open access: yesEURASIP Journal on Advances in Signal Processing, 2017
A reverberation-time-aware deep-neural-network (DNN)-based multi-channel speech dereverberation framework is proposed to handle a wide range of reverberation times (RT60s). There are three key steps in designing a robust system.

Optimized gain functions in ideal time-frequency masks and their application to dereverberation for cochlear implants [PDF]

open access: yesJASA 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.

Channel and temporal-frequency attention UNet for monaural speech enhancement

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2023
The presence of noise and reverberation significantly impedes speech clarity and intelligibility. To mitigate these effects, numerous deep learning-based network models have been proposed for speech enhancement tasks aimed at improving speech quality. In

Single-Channel Speech Enhancement Techniques for Distant Speech Recognition

open access: yesJournal of Intelligent Systems, 2013
This article presents an overview of the single-channel dereverberation methods suitable for distant speech recognition (DSR) application. The dereverberation methods are mainly classified based on the domain of enhancement of speech signal captured by a

Parallel processing of distributed beamforming and multichannel linear prediction for speech denoising and deverberation in wireless acoustic sensor networks

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2023
More and more smart home devices with microphones come into our life in these years; it is highly desirable to connect these microphones as wireless acoustic sensor networks (WASNs) so that these devices can be better controlled in an enclosure.

Expectation‐maximisation for speech source separation using convolutive transfer function

open access: yesCAAI Transactions on Intelligence Technology, Volume 4, Issue 1, Page 47-53, March 2019., 2019
This study addresses the problem of under‐determined speech source separation from multichannel microphone signals, i.e. the convolutive mixtures of multiple sources. The time‐domain signals are first transformed to the short‐time Fourier transform (STFT) domain.

Tracking of Moving Sources in a Reverberant Environment Using Evolutionary Algorithms

open access: yesIEEE Access, 2022
This paper describes a source tracking technique in a reverberant environment using a new combination of an adaptive species-based particle swarm optimization (ASPSO) algorithm and a multiple signal classification (MUSIC) algorithm.
