This paper proposes a blind source separation system using directional microphone with pan-tilt actuator. The proposed system blocks the effect of sound reverberation by using directional microphones. We propose 3 modes based on pan-tilt actuator control to adapt to changing situations. In this paper, we evaluate the proposed system with word recognition rate.
