ABSTRACT:
For transmitting voice between subscriber stations of a radio system, particularly a mobile radio telephone system, whereby an analog voice signal is digitally coded by voice frames (S), the voice frames (S) are first converted into voice-coded voice frames (S1). Subsequently, a plurality of these voice frames (S1) is combined to form a multi-voice frame (MSF1). These multi-voice frames (MSF1) are transmitted with error-protection. At the reception side, the multi-voice frames (MSF4) are in turn divided into voice-coded voice frames (S4) and, subsequently, the digital voice information contained in the transmitted voice frames is in turn converted into an analog voice signal.
