A voice application is a collection of one or more VoiceXML documents. A VoiceXML document is composed of one or more dialogs. A single VoiceXML document serves as the application entrypoint. This is the VoiceXML document that the Tellme VoiceXML interpreter fetches when a customer dials the telephone number associated with your voice application. Upon execution of that document, the interpreter fetches dependencies including grammars, scripts, recorded audio, XML data, and additional VoiceXML documents as required by your application.

VoiceXML is an industry standard markup language for voice applications. The World Wide Web Consortium (W3C) standard VoiceXML specification provides a high-level programming interface to speech and telephony. VoiceXML is supported by companies like AT&T, Motorola, Sun, and IBM. Building with VoiceXML and related standards allow for:

W3C is pleased to receive the VoiceXML submission from AT&T, IBM, Lucent and Motorola. The submission provides a description of an application of XML for marking up dialogs for interactive voice response applications.

The World Wide Web Consortium, a key Internet standards body, said Tuesday it has published version 2 of VoiceXML, a standard for leveraging Internet technology in interactive voice response applications commonly used by businesses in handling customer phone calls.

A PHP class library that works with VoiceXML technology. This class library provides a API to write voiceXML scripts and integrate with the PHP language and a vendor specific database server. Knowing Perl CGI.pm will be a great asset to use it.

VoiceXML is an emerging standard for speech applications. An XML-based markup language, VoiceXML uses "tags" to define a call flow, the dialog between a computer and a person over the telephone.

The following table summarises the Voxpilot VoiceXML elements, listing the supported attributes, parents and children of each. Each element is a link to a page further describing the element and it's attributes and provides usage examples.

W3C has released a Last Call Working Draft for Voice Extensible Markup Language (VoiceXML) Version 2.0. Pending receipt of positive feedback on this draft, the W3C Voice Browser Working Group plans to submit the specification for approval as a W3C Candidate Recommendation; comments may be sent for consideration until May 24, 2002.

The W3C's Voice Extensible Markup Language (VoiceXML) Version 2.0 specification has been released as a Candidate Recommendation, together with an explicit call for implementation. "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.

A very nice explaination of what VoiceXML is and how it works. Besides that it shows you some very practical examples to understand the concept of VoiceXML.

A list of Voice XML References.

VoiceXML and SALT are both markup languages that describe a speech interface. However, they work in very different ways, largely due to two reasons: (i) they have different goals, (ii) they have different Web heritages.

In conjunction with this week's TMA Telephony Voice User Interface Conference (TVUI), the VoiceXML Forum proudly announces its strong support for the W3C's release last week of VoiceXML 2.0 as a Candidate Recommendation. The Forum sees VoiceXML 2.0 as a stable standard for creating voice applications, providing a key building block for enabling multimodal interaction on the World Wide Web.

The Web's leading standards group called on developers to implement its nearly finished specification for bringing voice interaction to Web sites and applications. The World Wide Web Consortium (W3C) on Tuesday issued VoiceXML 2.0 as a candidate recommendation, the penultimate stage in the consortium's approval process.

Whereas the VoiceXML Forum and the W3C have determined that it is in the best interests of the respective organizations and the public that they work together to further develop a dialog markup language, and in the furtherance of collaboration, the VoiceXML Forum and the W3C understand and agree that:

The VoiceXML Forum today announced support for the World Wide Web Consortium's (W3C) Multimodal Activity (http://www.w3.org/2002/mmi/) - a newly-formed working group which will look into standards and software to access web applications and services by voice, keyboard, key pad, mobile phones and devices. Members of the VoiceXML Forum, including AT&T, IBM, Lucent, Motorola, Nuance, and VoiceGenie will participate in W3C's efforts.

The VoiceXML Forum today announced its support for the World Wide Web Consortium’s (W3C’s) release of Voice Extensible Markup Language (VoiceXML) 2.0 as a Proposed Recommendation. VoiceXML 2.0 has advanced to the Proposed Recommendation stage, and is therefore one small step away from becoming an official W3C standard.

With VoiceXML, speech recognition application development is greatly simplified by using familiar Web infrastructure, including tools and Web servers. VoiceXML scripts resemble HTML scripts, but HTML is executed on a Web browser, whereas VoiceXML scripts are executed on a computer called VoiceXML Interpreter (gateway), which is accessed by a customer using a regular wireline or wireless phone.

The W3C has published an initial draft of VoiceXML 2.0, along with a list of intellectual property issues.

VoiceXML is the industry's open, standards-based development language for voice-driven solutions. It's endorsed by the W3C, the same organization that defines other key standards such as HTML. A growing number of carriers and corporations around the world use VoiceXML for customer care and enhanced service applications.
