Fetching, Storing and deleting TTS content ------------------------------------------------------------- 1. When the TTS receives an inline content, it has a content-id = associated with it. If it has a cache-control field, then that would = determine how long this content is kept on the server. However in case = of a scenario where there MIGHT be a need to keep TTS content for an = entire page browse (so no cache control is activated) and then if the = user navigates to a new page, the client would decide to delete that = particular TTS content, it cannot do so. Basically, there is no = DELETE_CONTENT directive that can take the "content-id" as a parameter. = If there are other ways to do this, these are not so clear.=20 2. For TTS content, the spec doesnt specify if content-id is needed for = both inline content and URI's. It specifies for ASR that content-id is = needed only for inline recognition grammars and not for external ones. 3. The spec does not specify which all TTS methods can have the content = as a payload. I would assume from the spec that only the SPEAK request = would have the content as a payload. However, the spec defines message = headers like "audio fetch hint" and "fetch hint" that is used with = SET-PARAMS, GET-PARAMS and SPEAK. They have values of "prefetch" = indicating that the content may be prefetched and "safe" that says the = content need to be downloaded only when needed. If (according to my = understanding) there is prefetch enabled with a SET-PARAM request, and = the content can be specified ONLY through a SPEAK request, I dont see a = prefetch capability here. There should be some method like LOAD-CONTENT = that can take either an inline content or a URI to fetch (and the = content addressed through a content-id).=20 Queueing ------------- MRCPv2 does not specify using a QUEUE method. If there are preloaded = content (for TTS) on the server that could be referenced using a = content-id, the client should be able to choose multiple content through = the id's and create a queue to be played back. It can be argued that = multiple SPEAK requests can be sent and they naturally form a queue to = be played back. However, consider the scenario where you have sent = multiple SPEAK and the TTS is playing them back. Then the client decides = to PAUSE this and play another TTS content. With the current spec, if = you pause this, the next SPEAK will be appended to this queue rather = than spoken immediately. If a STOP gets sent, the whole queue gets = cleared.=20 If a QUEUE is implemented, then this queue can be paused (through a = PAUSE_QUEUE or something) and a new TTS can be played. The TTS would = send back a PLAY_COMPLETE after which the client can resume playback of = the queue. =20 Audio recorder --------------------- MRCPv2 does not specify the use of an audio recorder with RECORD, and = FETCH capability. There is provision in the ASR methods for recording only those waveforms = that were used for recognition with fetch capability. ASR ------- 1. MRCPv2 does not have provision to delete pre-loaded grammars if the = client decides they are no longer needed. 2. No INTERMEDIATE_RECOGNITION_RESULT send event from the recognizer and = provision for setting this with the message fields (eg SET-PARAMS) best regards, Sailesh.

But the spec (draft-ietf-speechsc-mrcpv2-00 chapter 2 last paragraph and chapter 3.3) says that the media pipes MUST be shared by all media processing resources under that SIP session. Why this restriction? How would a sample for the 1:N use case look like? Especially how does the client know which RTP stream is used for ASR and which for SV/SI (if it does not have this info it has to send all audio data of every utterance to ASR and SV/SI, even if only ASR or SV/SI is activated at the same time)? The "i=" field (of the SDP session description) could be used to label the different media streams. Is the following sequence of messages MRCPv2 compliant?

There may be very good reasons=20 to send separate RTP streams to different media resources for the same=20 logical session. Given that we do not want to create extra SIP dialogs and=20 have multiple MRCP sessions as a side effect of that I think that some=20 explicit matching of RTP streams and MRCP control sessions is needed.

Hi,

I've got a question on the results returned in a RECOGNITION-COMPLETE message.  The example in section 8.8 shows these results being returned:

           <?xml version="1.0"?>
          <result x-model="http://IdentityModel"
            xmlns:xf="http://www.w3.org/2000/xforms"
            grammar="session:request1@form-level.store>
               <interpretation>
                    <xf:instance name="Person">
                      <Person>
                          <Name> Andre Roy </Name>
                      </Person>
                    </xf:instance>
                    <input>   may I speak to Andre Roy </input>
               </interpretation>
          </result>

Where does the x-model come from?  Nothing in any of the grammars says that this grammar (request1@form-level.store) should be populating an xforms model named "IdentityModel", nor that part of the results for the rule named "request" should be used to populate the instance's <Person>.  How is this expected to happen?
