The Voice Browser Working Group met on September 20-23 in Toronto hosted by Voice Genie. During the meetings we reviewed several interesting systems and software tool kits: * AT&T's Florence dialog system [1] * RDC--Reusable Dialog Components [2] * IBM's reference architecture for SCXML [3] * xHMI reusability We fine-tuned the CCXML document in preparation for moving from Last Call Working Draft to Candidate Recommendation in October. The Working Group also worked on specifying additional assertions for the implementation report for CCXML. We discussed the Data-Flow-Presentation architecture [4] which separates data model from flow model from presentation model. XML and ECMAScript are candidates for the data model. CCXML and/or SCXML may be used for the flow model. And VoiceXML 2.0, VoiceXML 2.1 and VoiceXML 3.0 may be used for the verbal presentation model. VoiceXML 2.1 can act as a verbal presentation "modality" but will need extensions in order to synchronize with other multimodal presentation modalities such as display (HTML) for multimodal applications We are considering adding several new elements for VoiceXML 3.0: * New element(s) for speaker verification/authentication--we reviewed the VoiceXML Forum's requirements for Speaker Verification and Speaker Authentication for VoiceXML 3.0 [5]. A subgroup of the Voice Browser working group will develop the VoiceXML specifications for speaker verification/authentication, while the VoiceXML Forum will review the specifications, provide additional use cases, and specify the exchange format for voice biometric information. * * The <data> element from VoiceXML 2.1--to access data in the flow component by the flow and presentation components. * * An element similar to <audio>--for presenting media such as video in VoiceXML 3.0. We are also considering enhancements for the <grammar> <audio>, and <record> elements and DTMF processing. Thanks to Voice Genie for providing an excelling facility for our meetings. The next Face to Face meeting will be in France on Feb 27-March 3. Our revised target publication dates are * VoiceXML 2.1--Proposed Recommendation in Mid October * Pronunciation Lexicon Specification (PLS)--Last Call Working Draft Early October * Semantic Interpretation (SIRS)--Candidate Recommendation Early October * CCXML--Candidate Recommendation Late October * State Chart Extensible Markup Language (SCXML)--Working draft Third Quarter 2006 Jim Larson Co-chair, Voice Browser Working Group [1] http://www.difabbrizio.com/papers/icassp2005-florence.pdf <http://lists.w3.org/Archives/Member/w3c-archive/2005Jun/att-0123/Florence_DM_Toolkit_-_W3C_MMI_-_20050627_-_di_fabbrizio_-_rev03.pdf> [2] http://jakarta.apache.org/taglibs/doc/rdc-doc/intro.html [3] http://jakarta.apache.org/commons/sandbox/scxml/ [4] http://lists.w3.org/Archives/Public/www-voice/2005JulSep/0009.html [5] http://www.voicexml.org/resources/SIV_requirements_for_VoiceXML_20050914.pdf
