METHOD AND DEVICE FOR SPEECH SIGNAL RECONSTRUCTION IN PACKET SWITCHED TELECOMMUNICATION NETWORKS |
摘要 |
The disturbing effects caused by the random delay suffered by the packets in the network are reduced by preventing the first packet of each talkspurt from suffering a random delay lower than a predetermined minimum delay. To this end the delay suffered by the first packet of a talkspurt is estimated and the packet is stored, before being introduced into the output queue of the node, for a time depending on the estimated delay. The delay estimate is made to converge to the actual value by a progressive synchronization of source and receiver clocks. |
