Resumen
The article delves in the conception and functioning of VoiceXML for web-based distributed conversational applications. VoiceXML as a language replaces the familiar Hypertext Markup Language interpreter with a VoiceXML interpreter, and the mouse and keyboard with the human voice. VoiceXML is an emerging standard Extensible Markup Language-based markup language for distributed web-based voice services. VoiceXML 1.0 was developed by the VoiceXML Forum, which released it in March 2000, and was accepted by the World Wide Web Consortium (W3C) two months later as the basis for developing a W3C dialogue markup language. VoiceXML contains a menu and a form. It enables a dialogue in which a user selects an item from a menu. The dialogue uses the menu element to carry out further instructions. The form is VoiceXML's basic dialogue unit, describing a set of inputs needed from the user to complete a transaction between the browser and a server. The grammars in VoiceXML are specified using the Java Speech Grammar Format. VoiceXML has been built on the same distributed model that has already proved so successful for visual web-based services.
