摘要

Method of detecting voice activity in a signal, this signal being cut into frames, and this method comprising a step of smoothing an initial decision "voice" or "noise", taken for each frame; wherein the smoothing step comprises a step of taking a final decision "voice" for the n-th frame if: - the initial decision for frame n is "voice"; - and the final decision for frame n-2 was "noise"; And - the energy of frame n-1 was greater than that of frame n-2; And - the energy of frame n is greater than the energy.
