The LOCATA Challenge: Acoustic Source Localization and Tracking
Christine Evers, Heinrich Loellmann, Heinrich Mellmann +4
The ability to localize and track acoustic events is a fundamental prerequisite for equipping machines with the ability to be aware of and engage with humans in their surrounding e…
Proceedings of the LOCATA Challenge Workshop -- a satellite event of IWAENC 2018
Heinrich W. Loellmann, Christine Evers, Alexander Schmidt +3
Algorithms for acoustic source localization and tracking provide estimates of the positional information about active sound sources in acoustic environments and are essential for a…
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…
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…
Robust coherence-based spectral enhancement for distant speech recognition
Hendrik Barfuss, Christian Huemmer, Andreas Schwarz +1
In this contribution to the 3rd CHiME Speech Separation and Recognition Challenge (CHiME-3) we extend the acoustic front-end of the CHiME-3 baseline speech recognition system by a…
Improving Blind Source Separation Performance By Adaptive Array Geometries For Humanoid Robots
Hendrik Barfuss, Walter Kellermann
In this paper, the concept of an adaptation algorithm is proposed, which can be used to blindly adapt the microphone array geometry of a humanoid robot such that the performance of…
