[Freeswitch-users] Re- mod_pocketsphinx working example

[Andrew Keil]

To FreeSWITCH users,

I am about to experiment with Speech Recognition inside FreeSWITCH and seem to have hit a wall.

After building FreeSWITCH 1.6.13 with asr_tts/mod_pocketsphinx uncommented successfully.
Then uncommenting from autoload_configs/modules.conf.xml <load module="mod_pocketsphinx/>.

Then trying to run the pizza demo from the old Wiki: https://wiki.freeswitch.org/wiki/Mod_pocketsphinx

I get the following:

I noticed that there is no grammar model "wsj1" inside /usr/local/freeswitch/grammar/model
Also I cannot find wsj1 anywhere from the src or freeswitch files online.  Does anyone have a tar.gz version of this?  So at least I can get past this issue.

Then I decided to follow the Lua directory example: https://freeswitch.org/confluence/display/FREESWITCH/Lua+ASR+TTS+Directory+Example

About half way down it states:
==========================================

Next we create our dictionary and language model file. Change your directory to /usr/local/freeswitch/grammar and create a file called directory.sent
We are using Matthew Williams and Joe Smith as our examples.
<s> MATTHEW_WILLIAMS </s>
<s> MATT_WILLIAMS </s>
<s> JOSEPH_SMITH </s>
<s> JOE_SMITH </s>

Type make in the /usr/local/freeswitch/grammar directory.

This should give you the following files.
ls -la directory
-rw-r--r--  1 root root   82 2008-08-13 10:59 directory.dic
-rw-r--r--  1 root root  727 2008-08-13 10:59 directory.lm

This does not work since the "make" does not work here!
Any ideas?

So far not much luck.  I understand that pocketsphinx is not really a production product, however my client would like to make use of it for internal testing only.

Any assistance would be great.

Thanks in advance,

Andrew Keil
