Abstract
The present invention relates to a method of reducing noise in a speech detection system. The phases of at least two noise-affected signals are estimated. The phase estimate and the phase compensation required for the noise reduction are performed in the frequency domain. The background noise and the transient behavior of the enclosed space are simultaneously estimated.
