Multi-channel signals captured by spatially separated sensors often contain a high level of data redundancy. A compact signal representation enables more efficient storage and …
Blind source separation (BSS) of audio signals aims to separate original source signals from their mixtures recorded by microphones. The applications include automatic speech …
This paper describes multichannel speech enhancement for improving automatic speech recognition (ASR) in noisy environments. Recently, the minimum variance distortionless …
In this paper, we address the problem of extracting all super-Gaussian source signals from a linear mixture in which (i) the number of super-Gaussian sources K is less than that of …
This article describes a computationally-efficient statistical approach to joint (semi-) blind source separation and dereverberation for multichannel noisy reverberant mixture signals. A …

Multichannel blind audio source separation aims to recover the latent sources from their multichannel mixtures without supervised information. One state-of-the-art blind audio …
This paper describes a joint blind source separation and dereverberation method that works adaptively and efficiently in a reverberant noisy environment. The modern approach to blind …
In this paper, we address signal enhancement in underdetermined situations and propose new beamforming algorithms. Beamforming in (over) determined situations can successfully …
Overlapping speech and high room reverberation deteriorate the accuracy of automatic speech recognition (ASR). This paper proposes a method for jointly optimum source …
