could not find any complete document, for integration of unimrcp with freeswitch so thought of documenting it.
I had requirement to use MRCP interface for integration of ASR module with Freeswitch for Pizza demo.
here it is what i had to do.
1. prepare the Gino Pizza setup according to
http://wiki.freeswitch.org/wiki/Mod_pocketsphinx
- In ps_pizza.js change
var asr = new SpeechDetect(session, “pocketsphinx”)
to
var asr = new SpeechDetect(session, “unimrcp”);
2. In /usr/local/freeswitch/conf/autoload_configs/unimrcp.conf.xml file change the value of default-asr-profile to correct profile name as defined in one of file under mrcp_profiles
3. add follwing line
/usr/local/freeswitch/conf/autoload_configs/modules.conf.xml
<load module=”mod_unimrcp” critical=”true/>
so that mod_unimrcp module can be loaded by Free Switch.
That is all, you are all set to use ASR module using MRCP.

Hello
I am working to get Unimrcp working with freeswitch , I have followed your instructions , but didn’t succsess , here is my steps
1- install Unimrcp
2- run Unimrcp client , run Unimrcp server
3- Edit Ps-Pizza.js
var asr = new SpeechDetect(session, “unimrcp:unimrcpserver-mrcp-v1”);
4- run freeswitch
5- Dailed the pizza extensions 74992 , it asking do I need delivery or take out . but never detect it
6-run fs_cli log 7
here is the error I got
mod_unimrcp.c:1795 (ASR-0) RECOGNIZER channel error!
7- in the Unimrcp -Freeswitch wiki
http://wiki.freeswitch.org/wiki/Mod_unimrcp
There is a step for c/C++ to change the grammar
switch_ivr_detect_speech(session, “unimrcp”, “yesno”, “yesno-name”, “”, NULL);
Where can I do that
I don’t have any grammar file for unimrcp , under freeswitch/grammar only pizza grammar
8- all what I am trying to do , is to get use ASR with freeswitch , that is the reason I install Unimcrp , I need to use speech recognition with Freeswitch
Please , any instuctions how to achive that , I would really appreciate it
I am runing Unimrcp ” server and client ” is that enough or I need to install Nounace or other speech recognition software with Unimrcp
Thank you
Rania
you need to start your asr server,
I have put more details below
1. Downloaded FreeSWITCH 1.0.6.
$ cd /usr/local/src
$ wget http://files.freeswitch.org/freeswitch-1.0.6.tar.gz
$ tar xvfz freeswitch-1.0.6.tar.gz
2. Compiled the source.
$ ./configure
$ make
3. Installed.
$ make all install cd-sounds-install cd-moh-install
$ make samples
4. Started FreeSWITCH.
$ /usr/local/freeswitch/bin/freeswitch
5. Placed a call using softphone (x-lite), and confirmed FS worked.
6. Uncommented “asr_tts/mod_unimrcp” in “/usr/local/src/freeswitch-1.0.6/modules.conf”
7. Ran “make install” again.
8.Open /usr/local/freeswitch/conf/autoload_configs/modules.conf.xml, and add
mod_unimrcp. The ASR /TTS section of the file looks like:
<!– –>
<!– –>
<!– –>
<!– –>
<!– –>
9. Edited “/usr/local/freeswitch/conf/autoload_configs/unimrcp.conf.xml”:
<!– –>
10. Add “youasr1-mrcp-v1.xml” to “/usr/local/freeswitch/conf/mrcp_profiles/” (
. Restarted all the modules (asr-server, asr-mrcp, and FreeSWITCH), and placed a call
