CMU Sphinx / Forums / Help: Asterisk PocketSphinx Integration

Marco - 2010-12-09

Hi !

I want to integrate pocketsphinx with asterisk. I have pocketsphinx 0.6.1 and
Asterisk 1.4.38 installed.

I know that there is a tutorial about this
http://scribblej.com/svn/

I want using my italian acoustic model and language model that i created for
pocketsphinx but they were done with wav file at 16 Khz. So I must downsample
at 8 Khz the wav files, reconfigure sound feature parameters as in tutorial h
ttp://cmusphinx.sourceforge.net/wiki/tutorialam and retrain again, Isn't it?

sox file.wav -r 8k file.wav

Is this command correct to downsample my file to 8Khz?

sox file.wav -t raw -2 -c 1 file.raw

and is this correct to change the wav 8Khz file to raw file?

Thanks in advance

Marco

Hi Nickolay

I tried to change sound features parameters as in http://cmusphinx.sourceforg
e.net/wiki/tutorialam to
adatp them to my sound files with a sampling rate of 8Khz

So the default feat.params has these values:

-alpha 0.97

-dither yes

-doublebw no

-nfilt 40

-ncep 13

-lowerf 133.33334

-upperf 6855.4976

-nfft 512

-wlen 0.0256

-transform legacy

-feat CFG_FEATURE

-agc CFG_AGC

-cmn CFG_CMN

-varnorm CFG_VARNORM

I changed the values and my feat.params was

-alpha 0.97

-dither yes

-doublebw no

-nfilt 31

-ncep 13

-samprate 8000.0

-lowerf 200.00

-upperf 3500.00

-nfft 512

-wlen 0.0256

-transform legacy

-feat CFG_FEATURE

-agc CFG_AGC

-cmn CFG_CMN

-varnorm CFG_VARNORM

I added -samprate 8000.0 that in default feat.params was not present

After I have launched these commands

./scripts_pl/make_feats -ctl etc/evalita_train.fileids
./scripts_pl/make_feats -ctl etc/evalita_test.fileids
I have seen that feat.params was again default

-alpha 0.97

-dither yes

-doublebw no

-nfilt 40

-ncep 13

-lowerf 133.33334

-upperf 6855.4976

-nfft 512

-wlen 0.0256

-transform legacy

-feat CFG_FEATURE

-agc CFG_AGC

-cmn CFG_CMN

-varnorm CFG_VARNORM

So I can't change this file?

Please help me

Thanks in advance Nickolay

This issue was fixed in sphinxtrain trunk already

parameters as in tutorial http://cmusphinx.sourceforge.net/wiki/tutorialam and retrain again, Isn't it?
sox file.wav -r 8k file.wav

Yes

sox file.wav -t raw -2 -c 1 file.raw
and is this correct to change the wav 8Khz file to raw file?

It's not recommended to convert files to raw, you can train using wav files

I know that there is a tutorial about this
http://scribblej.com/svn/

Recommended tool to integrate asterisk with cmusphinx is UniMRCP with asterisk
plugin

Hi Nickolay

Thanks for the reply

I downloaded with svn Revision 10742: /trunk/SphinxTrain through the command

You need to update sphinxbase first

Hi Nickolay I tried to install sphinxbase snapshopt with this command

./autogen.sh --prefix=/home/marco/otto/sphinxbase

in folder /home/marco/otto/sphinxbase

and it's OK

then I launch make

It's OK

then I launch make ckeck

OK

When I launch make install I have this error

make: *** Errore 1

make: uscita dalla directory «/home/marco/otto/sphinxbase/include/sphinxbase»

make: uscita dalla directory «/home/marco/otto/sphinxbase/include/sphinxbase»

make: *** Errore 1

make: uscita dalla directory «/home/marco/otto/sphinxbase/include»

make: *** Errore 1

I must tell you the first time I launched only the command ./autogen.sh so it
installed in /usr/local but I don't want to install there How can I resolve
the problem

Sorry for my question I thank for your support

In autotools in unix there each package is build in source folder and
installed in installation folder. For example. you unpack sphinxbase to
/home/marco/work and install in /home/marco/local. Note that installation
folder and build folder are different ones. So your prefix option needs to be
different, for example

./autogen.sh --prefix=/home/marco/local

You can find more information about building software in Linux in autotools
manual.

Hi Nickolay thanks for the suggestion

BTW, I have a problem when I launch the command ./scripts_pl/make_feats.pl

in /home/marco/otto/evalita

-cfg not specified, using the default ./etc/sphinx_train.cfg

-param not specified, using the default ./etc/feat.params

Hi Nickolay I must thank you for your invaluable suggestions. Sorry but I' m
new to Linux

Now I want ask you a piece of information. Looking at http://code.google.com/
p/unimrcp/wiki/PocketSphinxPlugin I see that the acoustic model is semicontinuous. So It doesn't
accept my continuous acoustic model? Or I must train a semicontinuous model?

Thanks

Hello Nickolay

I'm following this guide http://code.google.com/p/unimrcp/wiki/PocketSphinxPl
ugin to integrate
PocketSphinx into UniMRCP server.

I have just installed UniMRCP 1.0.0 correctly and I have integrated it with
asterisk 1.4.38 through Asterisk Connector Bridge. Now I have a problem with
installing PocketSphinxPlugin.

I launched these commands in my /home/marco/unimrcp-1.0.0

./configure --prefix=/home/marco/unimrcp-1.0.0 --enable-pocketsphinx-plugin
--with-pocketsphinx=/home/marco/otto/pocketsphinx –with-
sphinxbase=/home/marco/otto/sphinxbase

OK

make

OK

make install

..

Marco, I explained you how --prefix is used and why it should be different
from the source folder. I explained you that in this thread earlier.

Hi nickolay

I Succeded in installing UniMRCP1.0.0 with PocketSphinx plugin and asterisk

I gave the command

in this folder there are these files

cmdln_macro.h pocketsphinx_export.h pocketsphinx.pxd ps_mllr.h

Hi Nickolay

I choose to follow http://scribblej.com/svn/

I installed astsphinx with success but I have problem with Client

After applying the patch

In folder /home/marco/asterisk/asterisk-1.4.38

I launch ./configure –prefix=/opt/asterisk

OK

then I launch make and I have this error

res_speech_sphinx.c -> res_speech_sphinx.o

res_speech_sphinx.c:78: warning: initialization from incompatible pointer type

res_speech_sphinx.c: In function ‘load_module’:

Hi!

Finally I succeeded in doing working asterisk with pocketsphinx following
http://scribblej.com/svn/
I have loaded my grammar and my acoustic model trained at 8 Khz and it works!
It recognizes italian digits

But I have a problem that it never stops listening

So if I speak it recognizes all that I say but when I stop speaking it doesn't
execute
exten => 123,n,SpeechDeactivateGrammar(evalita.lm)

So it remains in listening

These are my extensions

exten => 123,1,Answer()

exten => 123,n,SpeechCreate(Sphinx)

exten => 123,n,AGI(say.agi|'Benvenuto all'integrazione tra Sphinx e
Asterisk.')

exten => 123,n,SpeechActivateGrammar(evalita.lm)

exten => 123,n,AGI(say.agi|'Pronuncia le parole zero uno due tre quattro
cinque sei sette otto nove.'|1|yornprompt)

exten => 123,n,SpeechStart()

exten => 123,n,SpeechBackground(/tmp/yornprompt|10)

exten => 123,n,SpeechDeactivateGrammar(evalita.lm)

exten => 123,n,Log(NOTICE,${SPEECH_TEXT(0)})

exten => 123,n,AGI(say.agi|'You said: ${SPEECH_TEXT(0)}')

exten => 123,n,Goto(4)

Has somebody any suggestion?

Regards

Marco
