   <scribe> scribe: ddahl

 

   debbie: hoping to try to go through architecture and use case

 

   <scribe> agenda: connect use case to architecture

 

   dirk: dialog strategy, branding, replace TTS by NLG

 

   debbie: there could also be a voice interaction with audio

   files or hybrid audio and TTS

 

   jon: what about voice registry and W3C architecture

 

   dirk: we can do that in a follow-up call

   ... dialog strategy added to document version 1.1

   dirk: in section 3.2.2

   ... actually 3.2.2.1

   ... dialog registry may have to be omitted for some dialog

   strategies

   ... should not make any assumptions about the exact strategy

 

   debbie: we could give an example of VoiceXML as a frame-based

   strategy

 

   dirk: SCXML could be an example of state-based

   ... Trindikit would be information state update, could be

   starting to be commercialized

 

   debbie: amazon could be an example of frame-based because of

   slot-filling

 

   dirk: dialog manager would be a black box

   ... could there be a standard for dialog representation

 

   debbie: maybe would reduce interest on the part of people with

   a powerful dialog manager

   ... could separate dialog definition from execution

   ... in VoiceXML FIA is separate from the form

   ... maybe sometime we would want to have a dialog

   representation language

 

   dirk: Conversational Interfaces Community Group

   [8]https://www.w3.org/community/conv/

   ... was defining a dialog scripting language

   ... programming relying on states

 

      [8] https://www.w3.org/community/conv/

 

   debbie: where do we put the dialog strategy

 

   dirk: not visible, because it defines dynamic behavior

   ... executed by the dialog manager

 

   <scribe> ACTION:dirk to add examples of dialog strategies

 

branding

 

   dirk: in this architecture, there's no way to have platform

   branding

   ... this could be solved by having a dedicated dialog that does

   routing forward and backward

   ... there would be a dedicated core dialog, with its own TTS,

   or forward the audio directly to IPA

   ... replace TTS by NLG

   ... TTS could be part of NLG, "output" would make it more

   general

 

   debbie: how about "user input" and "system output" and explain

   in text

   ... there is a huge use case for visual output

   ... gestures and gaze are probably not going to be used very

   soon

   ... biometrics are common now

 

   dirk: we should give some hints about multimodality but most

   use cases are voice

 

use case walkthrough

 

   debbie: how do we represent that

 

   dirk: numbers in diagram referring to text

   ... sequence diagram would be hard to understand

 

   debbie: make steps in use case more explicit and number them

 

   <scribe> ACTION: debbie to update use case

 

   debbie: two separate diagrams

   ... first step is to expand on use case, then draw a second

   diagram

   ... should be able to do a bulleted list by tomorrow

 

   dirk: can update the diagram tomorrow

 

   <scribe> ACTION:dirk to update diagram with numbers referring

   to use case

 

Summary of Action Items

 

   [NEW] ACTION: debbie to update use case

   [NEW] ACTION: dirk to add examples of dialog strategies

   [NEW] ACTION: dirk to update diagram with numbers referring to

   use case

 

Summary of Resolutions
