The construction of a humanoid robot, which can communicate with humans
in a natural manner, is a worthwhile and challenging task alike. This
paper discusses some major difficulties encountered in acoustic signal
acquisition by the widely used humanoid robot NAO and the implications
for the design of the signal enhancement algorithms that are needed for
human-robot communication. Measurements with this low-cost robot, whose
microphones and loudspeakers are mounted in the head, show the
challenges for the noise reduction and acoustic echo control (AEC) due
to ego-noise and nonlinear loudspeaker characteristics. It is also
discussed how peripheral microphones at the limbs of the robot can
mitigate these problems and offer new prospects for multi-channel signal
