  2. The ‘XML’ in VoiceXML stands for: EXtensible Markup Language • XML is a meta-markup language, a set of rules for creating semantic tags used to describe data. • An XML element is made up of a start tag, an end tag, and data in between. • The start and end tags describe the data within the tags, which is considered the value of the element.

  3. VoiceXML takes this a step further, to the world of telephony! Several voice browser providers: TellMe, Pipebeach, VoiceGenie, BeVocal, etc. • Most let you sign up for free or a nominal charge, provided your application is small. • Most come with file management, a text editor and even a VoiceXML validator
