The Voice Extensible Markup Language (VoiceXML) 2.0 specification has been granted proposed recommendation status by the World Wide Web Consortium (W3C), and is one step away from becoming an official W3C standard.
VoiceXML is a specification used in conjunction with speech recognition and speech synthesis systems to support interactive voice response applications.
Using voice input to drive back-end applications is viewed by large companies as a cost-effective way to allow customers who prefer to use a telephone rather than the internet to perform transactions.
Last week, Australasian telecommunications carriers Telecom New Zealand and Australian subsidiary AAPT have announced plans for VoiceXML-based billing transactions.
The VoiceXML Forum also announced the availability of version 1.2 of the X+V (XHTML+Voice Profile) specification. X+V brings together voice modules that support speech synthesis, speech dialogues, command and control and speech grammars.
The latest version of X+V has been updated to complement the W3C's VoiceXML 2.0 specification.
The VoiceXML Forum is an industry organisation formed to create and promote VoiceXML and has more than 380 member companies.
