1. In a speech packet switching system having receiving means for receiving speech packets transmitted via a speech packet switching network, a variance absorbing buffer for temporarily storing therein the speech packets received by said receiving means to compensate for a variance of transmission delay times resulting from the transmission through said speed packet switching network, and reproducing means for reproducing the speech packets serially read out from said variance absorbing buffer,a speech packet switching method comprising the steps of:

  • determining a variance of transmission delay times of the speech packets in a talkspurt period received by said receiving means;

    determining a size of said variance absorbing buffer corresponding to the determined variance; and

    dynamically changing the size of said variance absorbing buffer for the next talkspurt period based on the determined size.
