VoiceXML is an application of the Extensible Markup Language (XML) which, when combined with voice recognition technology, enables interactive access to the Web through the telephone or a voice-driven browser. An individual session works through a combination of voice recognition and keypad entry. VoiceXML 1.0 was created through a collaboration of AT&T, IBM, Lucent Technologies, and Motorola, who were each working on their own approach but joined forces to create an open standard. Using XML, a programmer can enable voice recognition through the addition of a few simple tag.
0. Sample Chapter from the book: Early Adopter: VoiceXML: The book "Early Adopter: VoiceXML" is for those professional developers who wish to add a new language to their toolkit, and want to be in a position to take advantage of the imminent explosion in voice-enabled applications. The book aims to give the reader an in-depth analysis of the current state of VoiceXML technology. The information will help you develop voice-enabled applications now, and make sure you are ready for future advances of this quickly changing arena.

1. BeVocal Café: An excellent resource if you wish to build and test VoiceXML applications. I wrote my first VoiceXML application in just less than 15 minutes. The steps involved signing in (free), creating VoiceXML file (or taking one from sample VoiceXML files, and editing it), and then calling my application (using 1.877.33.VOCAL). BeVocal Café also has a very good collection of tutorials and articles on VoiceXML.

7. Technetcast: Introduction to VoiceXML. VoiceXML promises to free the web from the tyranny of the keyboard - and make possible voice-surfing from devices such as phones or microphones. An XML based standard for voice-browsing will significantly reduce the amount of time and effort needed to develop and deploy speech applications, because developers can use the same technology that they use for developing web sites. It will also make it possible to "voice-enable" web sites.

9. The Voice of XML: VoiceXML, an XML vocabulary for specifying IVR (Integrated Voice Response) Systems was submitted to the W3C more than one year ago. Initially it received little attention but now with more services like Tellme and BeVocal providing developer platforms for such applications the interest level has risen dramatically in the last couple of months. VoiceXML is 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. Its major goal is to bring the advantages of Web-based development and content delivery to interactive voice response applications.
