Hello,

I have tried the pizza demo and did it get to work so far.

However I would like to use pocketsphinx through event socket.
I saw in the wiki that there is a chapter for Speech Synthesis Commands:
http://wiki.freeswitch.org/wiki/Mod_commands#Speech_Synthesis_Commands
However this is empty.
Also
http://wiki.freeswitch.org/wiki/ASR
didn't give me a hint.

As I am not a Java programmer, it's hard for me to determine how the
pizza demo actually works.

Anybody has a sample how he did it e.g. in Php/Perl or so? (I am working
with Ruby)

Or back to the basics: Is it possible to use pocketsphinx through event
socket?

Best regards
Peter

You can accomplish this .... here is an example using ESL in perl

Hello Brian,

thanks for the info. I am a step further, but it cannot load the grammar
files.
I am sending through event_socket:

SendMsg
call-command: execute
execute-app-name: detect_speech
execute-app-arg: pocketsphinx yes no

However I get the message (also when I am using Pizza demo):

Any hint?

Some more info:
the system I am working on is a copy (dd copy) of a system where the
pizza demo works on.
The only thing I changed was to update to the current freeswitch trunk
12293 (it was 10003 before).

Do I need to update the model? I did a make in the model directory, but
no change.

Best regards
Peter

Peter,

You need the grammar files for the pizza demo:
http://wiki.freeswitch.org/wiki/Mod_pocketsphinx#Testing_with_the_Pizza_Demo
has lonks to premade fles for everyhting to get the pizza demo working
with pocketshinx. Those to not come with the source code when you
update from SVN.

Thanks Addison.
The Pizza files are there (as mentionned is it a copy of an already
working system).
In fact freeswitch is complaning about
/usr/local/freeswitch/grammar/model/communicator which he cannot load

So somehow freeswitch is not willing to open the files, but I have no
clue why. So any hints are welcome.

Best regards
Peter

I think you need to talk to Brian.

Apparently this is a "new" pocketsphinx which works on a different format from those found in the pizza demo.

Also, pocketsphinx crashes if it "hears" anything outside the grammar which apparently is a longstanding bug. Brian mentioned they are working on getting this fixed.


I kept getting:

2009-02-25 19:49:32 [ERR] mod_pocketsphinx.c:140 pocketsphinx_asr_load_grammar() Can't open dictionary C:\Source\freeswitch-snapshot\Debug\grammar\default.dic.
2009-02-25 19:49:32 [WARNING] mod_pocketsphinx.c:219 pocketsphinx_asr_close() Port Closed.

The suggestion was to "Just copy the cmudict.0.6d to default.dic, not sure how well it will perform on windows.. if it does badly you can slim the dictionary down to words you know you'll be using."

https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/cmudict/cmudict.0.6d

That gave me more problems so I'm waiting for the fix.

Mark.

Thanks Mark,

I now switched back to rev. 10003 and the Pizza works again.

Looks like the acoustical model wasn't installed... you might need to
remove all references of pocketsphinx and sphinxbase from libs and let
it redownload them all.

It works if you have the latest SVN with the new grammar files in jsgf
format. http://www.bkw.org/pizza_gram.tar.gz

Thank you Brian,

I will try this later.

Currently I was happy to get this working on SVN 10003.

As mod_pockesphinx has changed/evolved significantely: Will there also
be major changes in the events I receive through mod_eventsocket?
I spend some time on parsing the right data out of the eventsocket
interface, and I would just have an idea, if I will have to expect
significant work to do, when I later switch to the current SVN.

Will I need updated grammar files for the other models too?

Best regards
Peter
