The Call Control Extensible Markup Language (CCXML) provides declarative markup to describe telephony call control. CCXML can be used in conjunction with a dialog system such as VoiceXML.

Provides a rich, XML-based markup language for assisting the generation of synthetic speech in Web and other applications. The essential role of the markup language is to provide authors of synthesizable content a standard way to control aspects of speech such as pronunciation, volume, pitch, rate, etc. across different synthesis-capable platforms.

This document defines the syntax for specifying pronunciation lexicons to be used by Automatic Speech Recognition and Speech Synthesis engines in voice browser applications.

VoiceXML 2.1 specifies a set of features commonly implemented by Voice Extensible Markup Language platforms. This specification is designed to be fully backwards-compatible with VoiceXML 2.0 [VXML2]. This specification describes only the set of additional features.

Grammar Processors, and in particular speech recognizers, use a grammar that defines the words and sequences of words to define the input language that they can accept. The major task of a grammar processor consists of finding the sequence of words described by the grammar that (best) matches a given utterance, or to report that no such sequence exists. This document defines the syntax and the semantics of Semantic Interpretation Tags for use with the Speech Recognition Grammar Specification.

This document specifies VoiceXML, the Voice Extensible Markup Language. 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.

The purpose of this document is to help people understand the current challenges of deploying development-oriented services on mobile phones, evaluate existing technologies, and identify the most promising directions to lower the barriers of developing, deploying and accessing services on mobile phones and thereby creating an enabling environment for more social-oriented services to appear.

This is a sample short description for this specification; over time we will replace this description with a real one.

This document describes SCXML, or the "State Chart extensible Markup Language". SCXML provides a generic state-machine based execution environment based on CCXML and Harel State Tables.

VoiceXML 3.0 is a modular XML language for creating interactive media dialogs that feature synthesized speech, recognition of spoken and DTMF key input, telephony, mixed initiative conversations, and recording and presentation of a variety of media formats including digitized audio, and digitized video. The primary goal of the spec is to bring the advantages of Web-based development and content delivery to interactive voice response applications.

The W3C Voice Browser working group aims to develop specifications to enable access to the Web using spoken interaction. This document is part of a set of requirement studies for voice browsers, and provides details of the requirements for marking up spoken dialogs.

The W3C Voice Browser Working Group aims to develop specifications to enable access to the Web using spoken interaction. This document is part of a set of requirements studies for voice browsers, and provides details of the requirements for markup used for specifying application specific pronunciation lexicons.

Application specific pronunciation lexicons are required in many situations where the default lexicon supplied with a speech recognition or speech synthesis processor does not cover the vocabulary of the application. A pronunciation lexicon is a collection of words or phrases together with their pronunciations specified using an appropriate pronunciation alphabet.

A voice browser provides the means for people to use their voice to interact with appropriately designed applications. Users generally connect to voice browsers by dialling an access number. The voice browser in turn retrieves markup (e.g. VoiceXML) and other resources from an application server. In some situations it is appropriate to transfer the user from one voice browser to another. In other situations, the user may start from a visual web page and then transfer to a voice browser, yet another possibility is transfer from a voice browser to a human operator.

This document describes the requirements for how voice browsers and other call sites can cooperate by sharing data to create a seamless caller experience. An example of a potential resulting benefit to a caller is not having to re-enter the same information repeatedly at different call sites. A potential benefit for service providers is a flexible architecture for deploying and interconnecting disparate call sites.

The World Wide Web Consortium's Voice Browser Working Group is defining several markup languages for applications supporting speech input and output. These markup languages will enable speech applications across a range of hardware and software platforms. Specifically, the Working Group is designing markup languages for dialog, speech recognition grammar, speech synthesis, natural language semantics, and a collection of reusable dialog components. These markup languages make up the W3C Speech Interface Framework. The speech community is invited to review and comment on the working draft requirement and specification documents.

The W3C Voice Browser working group aims to develop specifications to enable access to the Web using spoken interaction. This document is part of a set of specifications for voice browsers, and provides details of an XML markup language for describing the meanings of individual natural language utterances. It is expected to be automatically generated by semantic interpreters for use by components that act on the user's utterances, such as dialog managers.

Multimodal browsers allow users to interact via a combination of modalities, for instance, speech recognition and synthesis, displays, keypads and pointing devices. The Voice Browser working group is interested in adding multimodal capabilities to voice browsers. This document sets out a prioritized list of requirements for multimodal dialog interaction, which any proposed markup language (or extension thereof) should address.
