1. A method for voice activity detection (VAD), the method comprising:
creating a signal indicative of a primary VAD decision;
determining whether a hangover addition of the primary VAD decision is to be performed;
creating a signal indicative of a final VAD decision at least partly depending on a hangover addition determination;
wherein determining hangover addition is based on a short term activity measure and a long term activity measure, wherein the long term activity measure is deduced from N_lt latest primary VAD decisions or from N_lt latest final VAD decisions.
