Abstract(in English) | This paper presents the auditory system in a personal robot, PaPeRo, which consists of sound-source localization, noise cancellation, and echo cancellation. 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. |
