A set of specifications for a high-level programming interface to speech and telephony resources for the development of speech recognition technology. Voice XML is based on the industry standard XML developed by the World Wide Web Consortium (W3C) for use on the World Wide Web (WWW). See also speech recognition and XML.
An extension to XML that defines voice segments and enables access to the Internet via telephones and other voice-activated devices. AT&T, IBM, Lucent and Motorola created the Voice XML Forum in 1999 to support this development. In 2000, the Forum became a program administered by the IEEE Industry and Standards Organization (IEEE-ISTO). Voice and Video VoiceXML is also used to include video and provide interactive voice and video response (IVVR) systems. For more information, visit www.voicexml.org. See XHTML+Voice and CCXML.
