VXML
According to the
VoiceXML Forum
(
www.voicexml.org) Voice
Extensible Markup Language (VoiceXML) is a markup language for
creating voice user interfaces that use automatic speech recognition
(ASR) and text-to-speech synthesis (TTS). AT&T, IBM, Lucent and
Motorola founded the VoiceXML Forum, a global industry organization,
in March, 1999 to promote and to accelerate the adoption of
VoiceXML-based applications worldwide.
More than 10,000 commercial VoiceXML-based speech applications have
been deployed across a diverse set of industries, including financial
services, government, insurance, retail, telecommunications,
transportation, travel and hospitality. Millions of calls are answered
by VoiceXML applications every day!
The VoiceXML Specification
Version 1.0 of the VoiceXML specification was delivered to the W3C in
May 2000. Today, the W3C has published both Version 2.0 and 2.1 of the
VoiceXML specification as final "Recommendations." A W3C
Recommendation is the equivalent of a Web standard. The W3C, with
input from the VoiceXML Forum and the industry at large, is currently
working on Version 3.0 of the VoiceXML specification.
The VoiceXML Advantage
VoiceXML is the only XML-based speech language specification to
receive the W3C's Final Recommendation. VoiceXML simplifies speech
application development by permitting developers to use familiar Web
infrastructure, tools and techniques. VoiceXML also enables
distributed application design by separating each application's user
interaction layer from its service logic. Most developers find
VoiceXML application development at least three times faster than
development in traditional interactive voice response (IVR)
environments. For these reasons, VoiceXML has been widely adopted
within the speech industry.
