Abstract
A noise elimination method and apparatus. The method eliminates noise from an input signal containing a voice signal mixed with a noise signal. The method includes detecting a noise section, in which the noise signal is present, from the input signal; obtaining a weight to be used for the input signal from signals of the noise section; and filtering the input signal using the obtained weight. The method and apparatus enable a mobile robot to eliminate noise in real time and effectively detect and recognize voice.
