Hi,
I need help regarding loading and activating multiple grammars.
Per FS-2906 <https://freeswitch.org/jira/browse/FS-2906>, it is possible to load multiple grammars from FreeSwitch.
I have tried the same using following commands from my C# code. The FS version I have is 1.3.17.
That appears to be some sort of random dev version from 5+ years ago. I’d suggest starting with looking at a a recent release and if you are still having issues work from there.
InboundSession.Execute("detect_speech", "unimrcp {start-recognize=false}yesnod yesnod"); InboundSession.Execute("detect_speech", "unimrcp {start-recognize=true}yesno yesno");
I can see that there are two DEFINE-GRAMMAR requests sent to the LumenVox Speech Server. One with yesnod.gram and another with yesno.gram But there is only one session mentioned in the RECOGNIZE request where as I am expecting it to be having both the sessions described in the DEFINE-GRAMMAR request. Any idea?
MRCP/2.0 226 RECOGNIZE 3 Channel-Identifier: 115483E487508175CFDF@speechrecog Content-Type: text/uri-list Cancel-If-Queue: false Start-Input-Timers: false Speech-Complete-Timeout: 3000 Content-Length: 13
session:yesno
There should be session:yesnod also.
I do not see a way to do this in detect_speech.
Any help would be great.
Here is the define grammar message too…
