Abstract
A Voice Over Internet Protocol (VOIP) receiver (), operating in conjunction with a transmitter () receives a sequence of voice packets representing a speech utterance transmitted over a VOIP wireless interface (). A receive packet buffer () buffers the received sequence of voice packets after receipt and before playback of reconstructed speech. A processor (), operating under program control, determines a transmission buffer () delay of a first packet in the sequence of packets representing the speech utterance. The control processor () further sets a prescribed amount of delay in the receive packet buffer () based upon the transmission buffer () delay so that the transmission buffer delay+receive buffer delay=a predetermined total delay. The status of the receiver buffer () is monitored and tracked by or fed back to the transmitter side to minimize receive buffer () under-runs by use of CDMA soft capacity (), link dependent prioritization (), real-time packet prioritization () and/or variation of vocoder () rates ().
