Voice Document Files™ (VDFs) are stand-alone VoiceXML files embedded with the VANGUARD Player, a text-to-speech playback control engine that responds using intuitive voice commands or pressing buttons on a keypad. Voice Document Files can exist on any network and are accessible via a voice browser platform. Voice browsers can be telephony based or computer based, providing multiple access points of VDF retrieval. Convert your documents to VDFs using VANGUARD Producer.
