1. , in the digital mobile terminal that uses discontinuous transmission, generate the method for comfort noise, may further comprise the steps:

  • Respond voice intermittently, cushion one group of speech coding parameters;

    In average period, substitute this group speech coding parameters of not representing background noise with the speech coding parameters of representing background noise;

    WithThe speech coding parameters of average this group,Wherein alternative steps may further comprise the steps;

    Measure speech coding parameters distance each other between interior each frame average period;

    Identification interior those speech coding parameters that have ultimate range to other parameters average period;

    WithIf this distance surpasses predetermined threshold, then be used in average period a speech coding parameters that has a speech coding parameters of minimum measuring distance or have a median to other speech coding parameters and substitute the speech coding parameters of being discerned.
