Abstract
A system and method for reducing delay introduced by de-jitter buffers in a VoIP network is presented. The method aspect for receiving and presenting speech data received from a VoIP network comprises monitoring speech-related packets received from a packet network and based on the monitoring, either maintaining a normal speech rate, compressing the speech rate or expanding the speech rate. The speech associated with the received packets is played out (presented audible via a speaker or other means) at the normal, compressed or expanded speech rate.
