摘要 |
Systems and methods for dynamically optimizing the fidelity of a speech signal received from a wireless telephony device and transmitted through a packet-switched network. In an exemplary embodiment, at least one Quality of Speech (QoS) transmission characteristic is determined for a packet-switched network intermediate to the a first Media Gateway (MGW) and a second MGW; the fidelity of speech transmitted through the packet-switched network being a function of the QoS transmission characteristic. A speech codec is dynamically-selected as a function of the QoS transmission characteristic of the packet-switched network. The speech signal is encoded into speech data using the dynamically-selected speech codec, and transmitted through the packet-switched network from the first MGW to the second MGW. The second MGW decodes the speech data using the dynamically-selected speech codec. |
