The ETSI standard TS 102 361-1 does not specify any particular vocoder for DMR, it's up to manufacturers to choose one, and I think AMBE was the solution that was converged upon by everyone. I believe there are some vendors which do provide alternative vocoders for their DMR transceivers. One of them is Hytera. But otherwise there is no restriction in the standard as to what the audio payload should be. There are only some technical and practical considerations, such as the availability of a dedicated chip in order to meet the stringent power budget of handheld terminals.
