D-STAR is all data, there is no voice only and no data only. Part of the data is used to carry a messaging service (GPS, Short Messages, Etc.) the equivalent of 1200 bps and another 3600 bps worth of the total 4800 bps data signal is encoded with audio and its forward error correction .... as others have commented you can't send only one or the other and in marginal conditions the "message service" portion will false the receiver into thinking you sent some audio in the data stream.
