Subject: [Freeswitch-users] load multiple grammar

Hi,

I need help regarding loading and activating multiple grammars.

Per 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.

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…
