Hi, Expert
We have a customer need to put all of the ASR grammars in their ASR server. We need OD to tell their ASR server which grammar file will be used in the request, it needs OD to pass the grammar file path and name to ASR server, then ASR will use this grammar on local machine.
Example: file:///C:\\grammars\mygrammar.grxml
My question is how DD can pass this infomation to ASR server, by MRCP? how to do?
and what is the mechanism of communication between OD,MPP and ASR?

This is a big issue for us now, need you help.

Thanks,
Yunjiao

Hi, Yunjiao! We do not support grammars quite like we do phrase sets. It may be possible to use "external grammars" to accomplish this. But some one would have to try it out. You would not be able to simulate this application only run it on the platform if the grammars were local to the ASR file system file://.... .

I do not know of anyone that is doing this but it may work.

Thanks, we are considering to use external grammar. External grammar will put the URL in vxml file generated by OD, then MPP will get this vxml include the grammar URL. but how MPP will do after it get this vxml? Can it pass this URL info to ASR? or MPP would get the grammar by itself according to this URL?
