1. A method for transmission of voice information between subscriber stations of a radio system, comprising the steps of: providing input analog voice information; digitally encoding said analog voice information to produce input voice frames; converting the input voice frames into first voice-coded voice frames; combining a plurality of first voice-coded voice frames, that are allocated to a subscriber, to form a multi-voice frame; error protection encoding said multi-voice frame; dividing said multi-voice frame into a plurality of sub-blocks; transmitting said sub-blocks separately from one another on at least one transmission channel; receiving said sub-blocks from said at least one transmission channel; reforming said multi-voice frame; error protection decoding said multi-voice frame; dividing the received multi-voice frame into second voice-coded voice frames; digitally decoding said second voice-coded voice frames to produce output voice frames; and converting digital information in the output voice frames into analog voice information; wherein determination of the plurality of voice frames combined to form a multi-voice frame ensues dependent on a level of quality of said at least one transmission channel in combination with the delay in transmission of the multi-voice frame.
