coolrakib - 2010-09-08

hi,
i cannot install the pocketsphinx in CentOS which i need to integrate with
asterisk. i tried the link
http://scribblej.com/svn/ . But no luck. is there
any other way of doing this??????
actually i need to convert Voices (some names and numbers) to text as output.
and then using the text to dial an extension of asterisk!!

You have two ways to solve this issue:

Explain what failed with http://scribblej.com/svn/ in very detail. Remember, the more detailed description you'll get the faster the problem will be solved.

Use UniMRCP with pocketsphinx plugin and asterisk MRCP extension

thanks for the reply ..............
i would like to go with the no 1 procedure....

1) Successfully compiled the asterisk with sphinx.patch

2) sphinxbase-0.6.1 & pocketsphinx-0.6.1 are also installed successfully

3) astphinx is installed with CPPFLAGS & LDFLAGS as described at the link.

4) lib files are also created with "echo "/opt/sphinx/lib/" >
etc/ld.so.conf.d/sphinx.conf " .

5) then i created a file named sphinx.conf under /etc/asterisk directory for
client configuration in which the stated lines are copied.

Now i dont understand what is the server configuration file look like!!!!

& what i have to do next????

Now i dont understand what is the server configuration file look like!!!!

Server configuration file should be the following text file:

-hmm /home/chris/ast/sphinx/Communicator_semi_40.cd_semi_6000 -dict mydict -lm yesno -samprate 8000

Here -hmm points to the acoustic model -dict to the dictionary and -lm to the
language model

& what i have to do next????

After you run the server and asterisk you can dial the extension and test
recognition

where should i put this file ???

what will be the name of the file ???

and should i add the (#!/bin/bash) at the top & make it executable or just the
lines you stated???

and what will be the command to run the server????

again thanks for replying...........

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Nickolay V. Shmyrev - 2010-09-08

where should i put this file ???

In the same folder with astsphinx. You point this file as the second argument
to astsphinx

$ astsphinx 10069 ./[b]configfile[/b] yesno phonetree compass 2>/dev/null

what will be the name of the file ???

Any name you like. configfile for example

and should i add the (#!/bin/bash) at the top & make it executable or just
the lines you stated???

No

when i try to create grammar it says

./lmgen.pl cmudict.txt mydict phonetree

Creating /tmp/text

Creating /tmp/wfreq

Creating /tmp/vocab

Dictionary mydict exists, so preserving existing entries.

Outputting new dictionary mydict

Cannot open for writing: mydict

and asterisk cannot execute this prioroty and later ones in the dialplan .....

exten => s,n,SpeechActivateGrammar(yesno)

Cannot open for writing: mydict

This is the problem with file permissions. Remove the file mydict and try
again.

coolrakib - 2010-09-14

still asterisk cannot execute this prioroty and later ones in the dialplan
.....

exten => s,n,SpeechActivateGrammar(yesno)

what to do???????????
does it mean yesno is not created?????

Try to dump astsphinx log into a file. To do that run

astsphinx 10069 ./configfile yesno phonetree compass 2> logfile

post the log here or check yourself.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

coolrakib - 2010-09-14

the logfile says::

Yesno is generated with this command

$ lmgen.pl yesno.txt mydict yesno

Please read the documentation again carefully

Yes, it's good. And you can do the same with yesno.txt

# cat>yesno.txt yes no

there is already a variant of yestno language model in one of the tarballs.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

coolrakib - 2010-09-15

& just to let you know... when i run lmgen.pl command it does not create

Hello

hey what is cmuclmtk how can i install this?????

You can find a link to cmuclmtk on downloads page http://cmusphinx.sourceforg
e.net/wiki/download

& just to let you know... when i run lmgen.pl command it does not create
anything in mydict file. it is always empty.

Sorry, that's another reason for your troubles. It should be more
straightforward. Actually lmgen has path to CMUSphinx hardcoded inside, you
need to open this script with a text editor and edit it to make sure it takes
correct files as an input

There are actually other way to build language model. One of them is online
lmtool. Please see our tutorial for more explanations
