The object of the invention is to provide a digital voice transmission system which suppresses, even when a long voice message is to be transmitted, an increase of the transmission capacity of a radio channel and, even if a drop of a division of divisionally transmitted voice compression data occurs, it is prevented that the voice data becomes difficult to hear. Data including a radio apparatus identification code, a message identification code, a division number, a digital voice compression data identification code, text message length information, a text message, reproduction time information, a system possession voice data identification code possessed by the transmission side irrespective of whether or not radio transmission is employed, system possession reproduction time information, a voice start code and digital voice compression data are transmitted. The voice compression data are divided with a length equal to an integral number of times that of a compressed voice data unit and are allocated to radio frames.
