Method for inband signaling control of vocoder bypass |
摘要 |
Vocoder bypass is provided using in-band signaling. In preferred embodiments of the present invention, three signaling channels are arranged for transmission within the compressed speech. Each of the signaling channels are communicated at a preferred rate to permit fast, reliable detection of conditions indicating vocoder bypass mode of operation, to negotiate suitable vocoder type if necessary, and to synchronize and communicate compressed speech in a vocoder bypass mode of operation.
