Abstract: Provided is an electronic program guide (EPG) service using an EPG extensible markup language (XML) in a digital audio broadcasting (DAB)/digital multimedia broad casting (DMB) system, and more particularly, a voice-enabled EPG provision method which enables a user to listen to desired program information without looking at a screen or a liquid crystal display (LCD) panel or make a desired input by voice or through other interfaces while watching a broadcasting program by adding a voice input/output function to an EPG service. In this method, a tag for an interactive voice input/output function, i.e., an interactive dialog between a user and a system, is added or extended to an EPG XML which was designed to provide a text or screen-based EPG service. Therefore, the DAB/DMB system can have the voice input/output function in addition to text and graphics output functions. These functions enable a user to listen to or view desired program information through a screen, by voice, or in an integrated mode of the screen and voice while on the move.
