The IBM developerWorks have a new article by Jeff Kusnitz, Senior Software Engineer, IBM. In this article the author introduces the new features in VoiceXML 2.1 which are few, but significant such the data tag, foreach, mark, grammar …etc. There is many interesting examples about how to use these tags and their attributes.
VoiceXML 2.1 was never intended to be a replacement for VoiceXML 2.0. The intent was that it include a small number of features that were not included in VoiceXML 2.0, but were deemed significant enough to warrant documenting and standardizing. VoiceXML 2.1 has met these goals — it contains just eight features, of which only two are completely new; the other six are enhancements to existing VoiceXML elements. In this article, learn about these many features, as well as a few other significant areas of work in the voice application/standards arena.
