Speech Dereverberation Based on Generative Adversarial Network with Additive Frequency Domain Decomposition

open access: yes工程科学与技术, 2022
The reverberant speech signal includes different frequency components induced by the effect of path delay. The frequency components are correlatedly modulated in frequency domain.

Speech intelligibility improvement in noisy reverberant environments based on speech enhancement and inverse filtering

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2018
The speech intelligibility of indoor public address systems is degraded by reverberation and background noise. This paper proposes a preprocessing method that combines speech enhancement and inverse filtering to improve the speech intelligibility in such

Segmentation‐enhanced gamma spectrum denoising based on deep learning

open access: yesIET Communications, Volume 18, Issue 1, Page 63-80, January 2024.
This paper proposes a segmentation‐enhanced convolutional neural network‐stacked denoising autoencoder (CNN‐SDAE) method based on convolutional feature extraction network and stacked denoising autoencoder to achieve gamma spectrum denoising, which adopts the idea of data segmentation to enhance the learning ability of the neural network.

Inverse Filtering for Speech Dereverberation Less Sensitive to Noise and Room Transfer Function Fluctuations

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
Inverse filtering of room transfer functions (RTFs) is considered an attractive approach for speech dereverberation given that the time invariance assumption of the used RTFs holds.

An online algorithm for echo cancellation, dereverberation and noise reduction based on a Kalman-EM Method

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2021
Many modern smart devices are equipped with a microphone array and a loudspeaker (or are able to connect to one). Acoustic echo cancellation algorithms, specifically their multi-microphone variants, are essential components in such devices.

A Phase-Coherent Four-Stage Pipeline for the Dereverberation of Quránic Recitation

open access: yesInformation
The accuracy of spectro-temporal features for Makhaarij al-Huroof and Sifaat distinguishes between the ten canonical Qiraát recitation styles of the Holy Quran. However, real-world room reverberations blur formant contours and corrupt inter-word energies,

Inverse Filtering and Principal Component Analysis Techniques for Speech Dereverberation

open access: yesAdvances in Electrical and Electronic Engineering, 2016
In this work, we present a single channel approach for early and late reverberation suppression. This approach can be decomposed into two stages. The first stage employs the inverse filter to augment the signal-to-reverberant energy ratio.

Low Delay Noise Reduction and Dereverberation for Hearing Aids

open access: yesEURASIP Journal on Advances in Signal Processing, 2009
A new system for single-channel speech enhancement is proposed which achieves a joint suppression of late reverberant speech and background noise with a low signal delay and low computational complexity.

Improving the conditioning of the optimization criterion in acoustic multi-channel equalization using shorter reshaping filters

open access: yesEURASIP Journal on Advances in Signal Processing, 2018
In acoustic multi-channel equalization techniques, such as complete multi-channel equalization based on the multiple-input/output inverse theorem (MINT), relaxed multi-channel least-squares (RMCLS), and partial multi-channel equalization based on MINT ...
