Workshop on Speaker biometrics and VoiceXML 3.0 — Summary

Menlo Park Workshop

On 5-6 March 2009, the W3C Voice Browser Working Group held a Workshop on Speaker biometrics and VoiceXML 3.0 in Menlo Park, California, US, hosted by SRI International.

The minutes of the workshop are available on the W3C Web server:

There were 16 attendees from the following organizations:

This workshop was narrowly focused on identifying and prioritizing directions for SIV standards work as a means of making SIV more useful in current and emerging markets. Topics discussed during the workshop includes:

During the workshop we have clarified "Why SIV functionality should be added to VoiceXML" as follows.

SIV Resources

The major "takeaway" is our confirming SIV fits into the VoiceXML space and generating the "Menlo Park Model", an SIV available VoiceXML architecture, as below.

SIV Menlo Park Model

The discussion on the above "Menlo Park Model" includes:
  1. Main hidden security issues that people have concern about are idendified, and ways in which they can be realistically addressed are discussed. Those issues don't disappear but now we know we can address them.
  2. VoiceXML 3.0 could be an example of the Interaction Managers within the W3C's MMI Architecture. The synchronization and markup integration of multiple modalities should be addressed. There are likely to be multiple modalities/factors involved in an interaction using VoiceXML. Consequently, developers need a way to not completely separate those modalities.
  3. Collaboration with other W3C Working Groups and other standard bodies, e.g., OASIS/BIAS, is expected.

Note that the discussion during the workshop was mainly focused on the application side and provided little guidance for engine providers. So a good standard that would create a nice wrapper around speech engines would be needed. Classification, segmentation and identification should be also considered and the group needs to determine whether or not to include them in VoiceXML V3.0.

The Call for Participation, the Logistics, the Presentation Guideline, the Agenda and the Minutes are also available on the W3C Web server.
