Committee Description
The Vocoder Working Group was created to develop and support Vocoder standards for Project 25 compatible land mobile radio equipment. It is the goal of these standards to sufficiently define the Vocoder and specify verification methods such that competing manufacturers may produce inter-operable equipment. These standards will include a technical description of the Project 25 standard Vocoder, Improved Multiband Excitation (IMBE), as well as methods for verifying a manufacturer’s implementation of IMBE. In addition, this working group will maintain a reference Vocoder and a limited database of speech data files.
