Abstract
The invention provides a method of suppressing a background noise signal in a sampled noisy voice signal. The method comprises the following steps: digital frequency-domain processing of the noisy voice signal to produce time-domain filtering coefficients, and digital time-domain processing of the noisy voice signal in accordance with the filter coefficients to produce a voice signal in which the background noise signal is substantially suppressed.
