VoiceXML 2.0 and the W3C speech interface framework

The World Wide Web Voice Browser Working Group has released specifications for four integrated languages to developing speech applications: VoiceXML 2.0, Speech Synthesis Markup Language, Speech Recognition Grammar Markup Language, and Semantic Interpretation. These languages enable developers to specify quickly conversational speech Web applications that can be accessed by any telephone or cell phone. The speech recognition and natural language communities are welcome to use these specifications and their implementations as they become available, as well as comment on the direction and details of these evolving specifications.
