X+V 1.1 ---XHTML+Voice Profile

Introduction

This is X+V 1.1 ---an update to XHTML+Voice ---commonly refered to as X+V. This version of X+V has been updated to match Voice XML 2.0 (W3C Candidate Recommendation). X+V 1.1 also contains numerous updates and fixes based on over 2 years of implementation experience from IBM, Opera and other X+V partners. This specification is made up of the following documents:

The X+V 1.1 specification ---an XHTML modularization profile that voice-enables WWW content.

XML Schema files that normatively define X+V 1.1 ---see xhtml+voice11-schema.zip

Associated DTD and driver files that normatively define X+V 1.1 ---see xhtml+voice11-dtd.zip

X+V developers can also download the XML Schema, DTD files and examples as stand-alone files:

Abstract

X+V brings spoken interaction to standard WWW content by integrating a set of mature WWW technologies such as XHTML and XML Events with XML vocabularies developed as part of the W3C Speech Interface Framework. X+V brings together voice modules that support speech synthesis, speech dialogs, command and control, speech grammars, and the ability to attach Voice handlers for responding to specific DOM events, thereby re-using the event model familiar to web developers. Voice interaction features are integrated directly with XHTML and CSS, and can consequently be used directly within XHTML content.

X+V is designed for Web clients that support visual and spoken interaction. To this end, this document first re-formulates VoiceXML 2.0as a collection of modules. These modules, along with Speech Synthesis Markup Language and Speech Recognition Grammar Specification are then integrated with XHTML using XHTML modularization. Finally, we integrate the result with module XML-Events so that voice handlers can be invoked through a standard DOM2 EventListener interface to create an X+V multimodal framework.
