Abstract
The present invention relates to a method in a speech activity detector and a background estimator for updating a background noise estimate for an input signal. An input signal for the current frame is received and it is determined whether the current frame of the input signal contains non-noise. Further, an additional determination is made by analyzing at least the features related to the correlation and energy level of the input signal as to whether the current frame of the non-noise input includes noise, and determines that the current frame includes noise. If so, the background noise estimate is updated.
