1. A method for detecting speech frames belonging to a low energy sequence of a speech signal, said method comprising:

  • determining a speech energy in a current speech frame;

    estimating a speech energy level based on a speech energy in a plurality of speech frames;

    if said estimated speech energy level deviates at least by a predetermined amount from a predetermined nominal speech energy level, scaling said determined speech energy in said current speech frame; and

    deciding that said current speech frame belongs to a low energy sequence, if said, potentially scaled, frame energy is lower than a predetermined low energy threshold value.
