摘要Abstract: The paper proposes a semi-spherical microphone
array based sound localization system for a service
robot. The hardware of the proposed system basically contains
12 capacitor microphones disposed in two layers on
the semi-sphere of 19 cm diameter. It aims to estimate the
degree relationship between the main speaker and the robot
and provides the robot useful information for more
effective human-robot interactions. The proposed system
can determine the location of the voice according to energy
information between the main speaker and robot not only
in normal environment but also in blatant and/or reverberative
space. The experimental results show that the
proposed system has obtained satisfactory recognition efficiency,
moreover, raised the robotic friendliness and
adaptability.
