Abstract
This paper describes a new method for one channel noise suppression system which overcomes the typical disadvantage of one channel noise suppression algorithms — the impossibility of noise estimation during speech sequence. Our method is the combination of Wiener filtering and spectral subtraction. The noise can be successfully updated even during the speech sequences and that is why there is no need of the voice activity detector.
