Abstract:
Auditory System in a Personal Robot, PaPeRo
Design, implementation and evaluation results of the auditory system for
a personal robot, PaPeRo, is presented. The system consists of
sound-source localization, noise cancellation, and echo cancellation
combined with speech recognition. Sound-source localization incorporates
new formulae taking near-field conditions into account for offsetting
errors caused by the relative altitude of the speech source to the
microphones. In noise cancellation, a novel stepsize control assuming a
wide range of signal-to-noise ratios of the input signal helps achieve
both small residual noise and distortion in the noise-cancelled signal.
New double-talk detection in echo cancellation improves detection
performance by paying attention to the background noise in the detection
measure. Evaluation results with recorded signals in the real
environment demonstrates 40% higher source-localization performance, as
much as 65% and 71% higher speech recognition rates in noisy environment
and during robot utterances. Some video demonstrations are provided.
