Adaptive blind audio source extraction supervised by dominant speaker identification using x-vectors
Jakub Janský, Jiří Málek, Jaroslav Čmejla +3
We propose a novel algorithm for adaptive blind audio source extraction. The proposed method is based on independent vector analysis and utilizes the auxiliary function optimizatio…
MIRaGe: Multichannel Database Of Room Impulse Responses Measured On High-Resolution Cube-Shaped Grid In Multiple Acoustic Conditions
Jaroslav Čmejla, Tomáš Kounovský, Sharon Gannot +2
We introduce a database of multi-channel recordings performed in an acoustic lab with adjustable reverberation time. The recordings provide information about room impulse responses…
Cramér-Rao Bounds for Complex-Valued Independent Component Extraction: Determined and Piecewise Determined Mixing Models
Václav Kautský, Zbyněk Koldovský, Petr Tichavský +1
This paper presents Cramér-Rao Lower Bound (CRLB) for the complex-valued Blind Source Extraction (BSE) problem based on the assumption that the target signal is independent of the…
Block-Online Multi-Channel Speech Enhancement Using DNN-Supported Relative Transfer Function Estimates
Jiri Malek, Zbynek Koldovsky, Marek Bohac
This work addresses the problem of block-online processing for multi-channel speech enhancement. Such processing is vital in scenarios with moving speakers and/or when very short u…
