Voice signal processing delay evaluating method for packet switching network e.g. Internet protocol network, involves determining temporary gap between voice signals and calculating delay from gap and predetermined decoding time

摘要

The method involves decoding audio packets flow containing voice signal based on a predetermined decoding time. A part of one voice signal reconstituted by a telephone module is duplicated for constituting another voice signal. A temporary gap between the voice signals is determined. A voice signal processing delay is calculated from the gap and the predetermined decoding time. - Independent claims are also included for the following: - (a) a process of evaluating a transmission delay of a voice signal - (b) a telephone terminal equipment on a packet switching network including a device for evaluating processing delay of a voice signal and a device of evaluating a transmission delay of a voice signal - (c) a computer program on an information medium, comprising program instructions for implementing a process of evaluating processing delay of a voice signal and a process of evaluating a transmission delay of a voice signal.
