Robust multichannel equalization for blind speech dereverberation [PDF]

open access: yes, 2016
Acoustic reverberation arises from the reflection of sound waves within an enclosed space. It is generally desirable in music reproduction but can be detrimental to speech-related applications.

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

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

De-Noising Process in Room Impulse Response with Generalized Spectral Subtraction

open access: yesApplied Sciences, 2021
The generalized spectral subtraction algorithm (GBSS), which has extraordinary ability in background noise reduction, is historically one of the first approaches used for speech enhancement and dereverberation. However, the algorithm has not been applied

Two-Microphone Dereverberation for Automatic Speech Recognition of Polish

open access: yesArchives of Acoustics, 2014
Reverberation is a common problem for many speech technologies, such as automatic speech recognition (ASR) systems. This paper investigates the novel combination of precedence, binaural and statistical independence cues for enhancing reverberant speech ...

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.

Deep Learning Methods for Underwater Target Feature Extraction and Recognition

open access: yesComputational Intelligence and Neuroscience, Volume 2018, Issue 1, 2018., 2018
The classification and recognition technology of underwater acoustic signal were always an important research content in the field of underwater acoustic signal processing. Currently, wavelet transform, Hilbert‐Huang transform, and Mel frequency cepstral coefficients are used as a method of underwater acoustic signal feature extraction.

Blind‐Matched Filtering for Speech Enhancement with Distributed Microphones

open access: yesJournal of Electrical and Computer Engineering, Volume 2012, Issue 1, 2012., 2012
A multichannel noise reduction and equalization approach for distributed microphones is presented. The speech enhancement is based on a blind‐matched filtering algorithm that combines the microphone signals such that the output SNR is maximized. The algorithm is developed for spatially uncorrelated but nonuniform noise fields, that is, the noise ...
