Two Voice Specifications Updated: VoiceXML 3.0 and SCXML

The Voice Browser Working Group has published Working Drafts today of Voice Extensible Markup Language (VoiceXML) 3.0 and State Chart XML (SCXML): State Machine Notation for Control Abstraction. 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. SCXML is a general-purpose event-based state machine language that can be used in many ways, including with VoiceXML. Learn more about the Voice Browser Activity.
