A nice VXML tutorial provided by Dave Raggett to the W3C. A great introduction to VXML with code samples.

The pointer to the latest 2.1 draft specifications including errata. Version 2.1 is a minor refinement of 2.0 with features that are simple, already implemented by some vendors, and not already available within 2.0 version.

Official note specification; designed for creating audio dialogs that feature synthesized speech, digitized audio, recognition of spoken and DTMF key input, recording of spoken input, telephony, and mixed-initiative conversations. (W3C Note 05 May 2000)

The W3C specifications used by VXML to provide speech synthesis.

The upcoming call control language for more elaborate control than VXML transfer. CCXML uses VXML to specify dialogs with connected call parties.

XHTML+Voice profile is designed for Web clients that support visual and spoken interaction.

The VXML test suite provided by the W3C to demonstrate that the VXML standard can be implemented. This test suite is then used by the VoiceXML Forum as the basis for conformance activities.

Brief technical note showing the relationships between the various World Wide Web Consortium controlled formats.

Repository for this next generation of Web forms, including implementations, mailing lists, working group, and relationship with other W3C work. (W3C Document Formats domain)

This specification is the successor to XHTML forms, and benefits from the lessons learned in the years of HTML forms implementation experience. (W3C Working Draft 28 August 2001)
