Design of robust two-dimensional polynomial beamformers as a convex optimization problem with application to robot audition
Hendrik Barfuss, Markus Bachmann, Michael Buerger +2
We propose a robust two-dimensional polynomial beamformer design method, formulated as a convex optimization problem, which allows for flexible steering of a previously proposed da…
Efficient Target Activity Detection based on Recurrent Neural Networks
Daniel Gerber, Stefan Meier, Walter Kellermann
This paper addresses the problem of Target Activity Detection (TAD) for binaural listening devices. TAD denotes the problem of robustly detecting the activity of a target speaker i…
HRTF-based two-dimensional robust least-squares frequency-invariant beamformer design for robot audition
Hendrik Barfuss, Michael Buerger, Jasper Podschus +1
In this work, we propose a two-dimensional Head-Related Transfer Function (HRTF)-based robust beamformer design for robot audition, which allows for explicit control of the beamfor…
HRTF-based Robust Least-Squares Frequency-Invariant Polynomial Beamforming
Hendrik Barfuss, Marcel Mueglich, Walter Kellermann
In this work, we propose a robust Head-Related Transfer Function (HRTF)-based polynomial beamformer design which accounts for the influence of a humanoid robot's head on the sound…
Robust coherence-based spectral enhancement for speech recognition in adverse real-world environments
Hendrik Barfuss, Christian Huemmer, Andreas Schwarz +1
Speech recognition in adverse real-world environments is highly affected by reverberation and nonstationary background noise. A well-known strategy to reduce such undesired signal…
On the Impact of Localization Errors on HRTF-based Robust Least-Squares Beamforming
Hendrik Barfuss, Walter Kellermann
In this work, a recently proposed Head-Related Transfer Function (HRTF)-based Robust Least-Squares Frequency-Invariant (RLSFI) beamformer design is analyzed with respect to its rob…
