Chairs' report of the May Face-to-Face Voice Browser Working Group meeting

T-Systems hosted the W3C Voice Browser Working Group face-to-face 
meeting  in Berlin on May 23-25. 

We are currently reviewing all of the change requests deferred during 
the VoiceXML 2.0 and 2.1 specification process to identify those that 
will likely impact VoiceXML 3.0. The VoiceXML 3.0 language (public 
working draft is not yet available) will contain significant 
enhancements to VoiceXML 2.0/2.1, possibly including but not limited to 
speaker authentication/authorization, audio and video control, improved 
bargein, and improved resource management. 

We reviewed the latest draft of our state language, State Chart XML, 
(SCXML) and agreed to published it as a Working Draft.  It may be used 
as an enhanced state component in a future version of CCXML.  The 
relationship between VoiceXML and control languages such as SCXML and 
CCXML will be described in terms of a DFP (Data Flow Presentation) 
architecture. An overview of this archtitecture  is found at 

We met with the OMA and Multimodal Interaction working groups to discuss 
the relationships of the OMA multimodal architecture, the MMI 
architecture, and our DFP architecture.  We concluded that the 
architectures are quite similar with the possible exception of term 
names.  We also conferred with the MMI Working Group on how VoiceXML 
2.0/2.1/3.0 will fit into the Multimodal Architecture. 

Our next Face to Face meeting will be September 21-23 in Toronto.
