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 ...

Robust Audio Adversarial Example for a Physical Attack

open access: yes, 2019
We propose a method to generate audio adversarial examples that can attack a state-of-the-art speech recognition model in the physical world. Previous work assumes that generated adversarial examples are directly fed to the recognition model, and is not ...

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

Control Filter Estimation for Multichannel Active Noise Control Using Kronecker Product Decomposition

open access: yesIET Signal Processing, Volume 2025, Issue 1, 2025.
Active noise control (ANC) algorithms have been developed within the adaptive algorithm framework. However, multichannel ANC systems, which include numerous reference sensors, control speakers, and error microphones, require a very long control filter converging time for control filter estimation.

Refining the Extent and Depth of the Shear Zone Surrounding the Alpine Fault Using Receiver Function Harmonics

open access: yesGeophysical Research Letters, Volume 51, Issue 23, 16 December 2024.
Abstract Large continental transform faults are thought to cross‐cut the crust and extend into the lithospheric mantle. However, the strain distribution associated with these faults at mantle depths is not well understood. At the heart of this question is the rheology of the lithosphere: when stressed by displacement on a trans‐crustal fault, does the ...

Structured Sparsity Models for Multiparty Speech Recovery from Reverberant Recordings [PDF]

open access: yes, 2012
We tackle the multi-party speech recovery problem through modeling the acoustic of the reverberant chambers. Our approach exploits structured sparsity models to perform room modeling and speech recovery.

Time‐lapse applications of the Marchenko method on the Troll field

open access: yesGeophysical Prospecting, Volume 72, Issue 3, Page 1026-1036, March 2024.
Abstract The data‐driven Marchenko method is able to redatum wavefields to arbitrary locations in the subsurface, and can, therefore, be used to isolate zones of specific interest. This creates a new reflection response of the target zone without interference from over‐ or underburden reflectors.

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.

Multichannel equalisation for high-order spherical microphone arrays using beamformed channels

open access: yes, 2015
High-order spherical microphone arrays offer many practical benefits including relatively fine spatial resolution in all directions and rotation invariant processing using eigenbeams. Spatial filtering can reduce interference from noise and reverberation
