6. IAB conference call times, meeting frequency, and meeting length

The IAB agreed to change their conference call time to 1330 UTC from 16 March through 15 October and 2130 UTC from 16 October through 15 March.

The IAB agreed to experiment with the IAB meeting schedule between IETF 104 and the IAB retreat. Meetings will be scheduled for 60 minutes on the first, second, and third weeks of the month, with the option for the meeting on the second week of the month to be canceled if the IAB agrees to do so by the end of the previous week’s meeting.

7. Voice invocation and identifier comparison: How many layers to the API?

Ted Hardie observed that voice system inputs are getting more common, but they are being built without much regard for interoperability. Despite some very common linkages to external systems, ecosystems are siloed. Confusabilty for registered or local actions can be high.

When you say “Yelp me an open restaurant near here,” how do you know that you are getting’s service?

Currently, you are relying on the pipeline to have resulted in either a transcription that could be matched to, a registered action produced by, or a mark famous enough that the intent was reserved for that use.

Voice interactions can use multiple different pipelines:

  • Locale–>Language model–>phoneme identification–>contextual orthography model–>transcript
  • Language model stage one–>language model with identified language(s)–>intent model–>output action
  • Hotword–>conversational script–>branching intent model–>output action

This variation can occur within a single mobile system now. At the moment, getting interoperability between voice interactions and non-voice interactions is largely luck. Ted Hardie asked if there is anything the IAB can to do to develop a real strategy?

Stephen Farrell said it would be good if the IAB could try to document some of the issues.

Christian Huitema observed that it is difficult to do this sort of thing without personalization; these systems require a lot of training data.

Erik Nordmark noted that there is nothing in a string of phonemes to indicate when something is an identifier. Martin Thomson added that there are holes where identifiers can exist without context, which makes it more challenging.

The IAB agreed to continue thinking about this issue.
