Abstract

In this work, we propose a two-dimensional Head-Related Transfer Function\n(HRTF)-based robust beamformer design for robot audition, which allows for\nexplicit control of the beamformer response for the entire three-dimensional\nsound field surrounding a humanoid robot. We evaluate the proposed method by\nmeans of both signal-independent and signal-dependent measures in a robot\naudition scenario. Our results confirm the effectiveness of the proposed\ntwo-dimensional HRTF-based beamformer design, compared to our previously\npublished one-dimensional HRTF-based beamformer design, which was carried out\nfor a fixed elevation angle only.\n
