16:02:28 <ddahl> chair: debbie
16:03:08 <ddahl> scribe:ddahl
16:06:30 <ddahl> topic: interfaces document
16:06:44 <ddahl> https://w3c.github.io/voiceinteraction/voice%20interaction%20drafts/paInterfaces/paInterfaces.htm
16:08:19 <ddahl> dirk: changes to interfaces document
16:09:22 <ddahl> ...changes to rename API providers as External, new version of architecture
16:09:50 <ddahl> ... External Data, Services, IPA providers
16:10:37 <ddahl> ...architecture is version 1.3
16:12:38 <ddahl> ...also added descriptions to UML notation, added some links to explanation of UML
16:13:48 <ddahl> present:debbie,jon,jim,tobias,ulrike,dirk
16:15:18 <ddahl> dirk: looking at sequence diagram
16:16:14 <ddahl> ...added small internal call in case you don't need to access external services
16:16:48 <ddahl> ...or in case internal information supplements the external services
16:17:12 <ddahl> ...the internal "processDialogInput" is not optional
16:17:44 <ddahl> ...or it should be "processDialogInputs"
16:18:09 <ddahl> ulrike: what's the difference between "processInput()" and "processDialogInput"
16:19:25 <ddahl> dirk: "processInput" could trigger some internal "processDialogInput"
16:20:31 <ddahl> dirk: should add some more descriptive text
16:21:00 <ddahl> ..."processInput" has two paths, local or external
16:21:15 <ddahl> ...both should be combined to determine the next dialog step
16:22:08 <ddahl> ...as a result, you may call an external service
16:22:26 <ddahl> jim: change "opt" to "optional"?
16:22:34 <ddahl> dirk: this is also standardized in UML
16:23:15 <ddahl> ... the "opt service call" is also part of "processInput()"
16:23:39 <ddahl> ulrike: "processDialogInput" seems more like "process semantics"
16:24:45 <ddahl> present+ noreen
16:25:35 <ddahl> dirk: finally, "deliverResponse" and play back audio
16:26:19 <ddahl> ... "callService" is just a remote method call
16:28:01 <ddahl> dirk: should I explain that this is one cycle
16:28:34 <ddahl> tobias: there could be some indication that this could be a loop
16:29:21 <ddahl> debbie: it would be useful to have captions on the figures
16:30:22 <ddahl> dirk: it makes it clearer if everything has a return
16:31:02 <ddahl> ...tried to reduce the amount of interfaces we need to describe
16:32:21 <ddahl> ...could use "return value" instead of "clientResponse"
16:32:38 <ddahl> debbie: return value is implicit in the client input call
16:35:36 <ddahl> ulrike: is there something in the standard that would make this clearer?
16:37:35 <ddahl> dirk: also changed table in interface client input and external client input
16:40:08 <ddahl> debbie: do we have any way to report errors?
16:40:41 <ddahl> dirk: could be in multimodal output or we could gloss over error case
16:41:19 <ddahl> debbie: some kind of status
16:42:21 <ddahl> dirk: have "call result details" in a service call, or should that be reflected in client interaction
16:42:51 <ddahl> debbie: I think we should add that
16:43:21 <ddahl> dirk: success indicator plus optionally more detailed description
16:44:13 <ddahl> debbie: the user doesn't always need to know
16:45:02 <ddahl> dirk: the call to the Dialog might also fail
16:45:11 <ddahl> ...then the Client needs to know
16:45:48 <ddahl> ... will add something to table in Section 4.3
16:46:44 <ddahl> ...the next interface is External Client Input
16:47:46 <ddahl> ...return value is some semantic interpretation
16:48:31 <ddahl> ...arrays should be list, need to consider multi-intents
16:49:21 <ddahl> dirk: nbest intents can be included in multiple interpretations
16:49:52 <ddahl> ...for multi-intents don't cover
16:49:56 <ddahl> ...yet
16:51:43 <ddahl> tobias: what about a group of utterances with a similar meaning
16:52:16 <ddahl> dirk: many different utterances can be mapped to an intent
16:57:29 <ddahl> debbie: we should provide for multi-intents
16:58:01 <ddahl> tobias: we might want to think about how other AI's annotate confidence
16:58:31 <ddahl> ...can we standardize confidence
17:00:20 <ddahl> jim: confidence in AI's is not well-defined, they're just estimates
17:01:56 <ddahl> dirk: still need to talk about External Service Call
17:02:46 <ddahl> rrsagent, make logs public
17:02:53 <ddahl> rrsagent, format minutes
17:02:53 <RRSAgent> I have made the request to generate https://www.w3.org/2022/02/23-voiceinteraction-minutes.html ddahl
