In this work, an HRTF-based RLSFI beamformer design is proposed. The HRTF-based RLSFI beamformer accounts for the influence of a robot's head on the sound field. 

The performance of the new HRTF-based RLSFI beamformer is evaluated using signal-based measures and word error rates for an off-the-shelf speech recognizer, and is compared to the performance of the original free-field RLSFI beamformer design.

The experimental results confirm the efficacy of the proposed HRTF-based beamformer design for robot audition.
