Abstract: In this paper we present an algorithm for the robust estimation of the noise power from the speech signals contaminated by high non stationary noise sources for speech enhancement. The noise power is first estimated by minimum statistics principles with a very short window. From the resulting noise power excess, the overestimation is accounted for using recursive averaging techniques. The performance of the proposed technique is finally compared with the different existing approaches using various grading tests.
