  • Patent number: 7756484
    Abstract: A method for monitoring voice quality in a communication network. In a first embodiment, the method comprises the steps of: establishing a voice communication pathway (VCPW) between first and second telephone terminals; establishing speech cadence between first and second terminals, wherein the terminals alternate between opposing send and listen/receive modes such that when one of the terminals is sending a voice test message the other terminal is either listening for or receiving the voice test message and vice versa; and calculating a voice quality score for one or more received voice test messages. In a second embodiment, synchronous cadence is established between a plurality of telephone terminals and a voice recognition server (VRS).
