A basic VoiceXML application Basic rules Because VoiceXML is an extension of XML, you will have to follow the basic rules for XML, which include: * Well-formed XML documents: All elements must have a closing tag. * A root element: All documents must have a root element. The root element for a VoiceXML document is vxml. * Attributes: Attribute values must always be quoted. * Nesting: All elements must be properly nested.

Event handling Types of events An event is thrown by the VoiceXML platform for any number of reasons, such as a user not responding to an input, not responding correctly, requesting help, etc. An event is also thrown if there is a semantic error in the VoiceXML document, or when the element is encountered. The element generates an event (user-defined or system) and the element catches the event thrown by the VoiceXML document, dialog, or form item.

VoiceXML example Creating the welcome message In this VoiceXML example, you will be creating an application that gives you a selection to choose from. Once you make a selection, you are taken to the appropriate document or dialog. In this section, you will create the main greeting message of the application. In the code below, the user hears a

VoiceXML concepts Dialogs The VoiceXML application structure model is a Finite State Machine. A user of a VoiceXML application is always in one conversational state or dialog at a given time. Each dialog is followed by another dialog, and if no dialog is specified next, then the execution of the VoiceXML application is terminated. There are two types of dialogs: forms and menus. Forms collect user inputs in the form of values, just like an

VoiceXML Tutorial Purpose This tutorial teaches you how to develop Voice Extensible Markup Language (VoiceXML) based applications. VoiceXML is markup language that brings Web-based applications and content delivery to interactive voice response applications; input is in the form of audio (voice or DTMF keypad tones), as is output (text to speech voice or recorded audio files). This tutorial provides an introduction to basic VoiceXML development. It describes the tools you'll need to build Voic…
