VXML platform - IVR Platforms

VXML, or Voice Extensible Markup Language, is a standard XML format for specifying IVR dialogs using voice-recognition, DTMF and speech generation technology. VXML leverages Internet technologies like the HTTP protocol for delivery of VXML formatted dialogs along with voice-recognition grammars. Just as HTML scripts are interpreted by a visual web browser, VXML scripts are interpreted by a "voice browser" or "VXML gateway", which interprets and renders VXML content on the PSTN or on some other audio network like VoIP.

In today's market place VXML is generally broken up into two separate pieces. An Application Server provides the VXML content and a Voice Browser that interprets the VXML Script from an Application Server. These two pieces can be provided by the same vendor or the can be mixed and matched for best of breed services.
