Topic: control portion of protocol based on MRCP subset (this thread http://lists.w3.org/Archives/Public/public-xg-htmlspeech/2011Jun/0035.html)


-        Agreed that this subset is appropriate for ASR & TTS.

-        Unclear whether recording should be included.  Agreed to escalate this to the XG.  IF there's agreement that recording scenarios are common and valuable, we'll include that portion in the protocol.  OTHERWISE we'll omit it, since it's still possible through more convoluted means.

o   We discussed this in the main call with the XG.  General agreement was that recording isn't something we need to solve, and that it should be possible as a side-effect of recognition (i.e. <ruleref special="GARBAGE"> and retain the audio).

-        While services are free to implement a subset of the protocol (e.g. only SR or only TTS portions), clients will need to implement the full set.

Topic: RTP

-        Agreed that it is unneeded, for the reasons stated http://lists.w3.org/Archives/Public/public-xg-htmlspeech/2011Jun/0029.html

-        The basic design approach provides an extensibility mechanism so that if new scenarios emerged in the future that required RTP or another protocol, (http://lists.w3.org/Archives/Public/public-xg-htmlspeech/2011Jun/att-0008/speech-protocol-basic-approach-01.html)

Topic: SDP

-        Agreed, like RTP, that it is unneeded given the context we already have as a byproduct of our design approach.  (See also the last paragraph here: http://lists.w3.org/Archives/Public/public-xg-htmlspeech/2011Jun/0042.html)

Topic: session initiation & media negotiation (http://lists.w3.org/Archives/Public/public-xg-htmlspeech/2011Jun/0042.html)

-        People haven't had a chance to review this.  Will discuss more over the coming week.

-        GET-PARAMS is resource specific, so works a little differently to what's written here.  (Robert will need to re-think and make another proposal)

Next steps:

-        Continuous speech proposal (Milan)

-        Redraft to incorporate everything we've discussed so far (Robert)

-        Examine whether the recognition portion of the protocol can handle extended scenarios, like verification, etc. (Michael)
