Hi,

I try to change pocketsphinx's grammar from default (english) to german.
I found this archive
(http://www.repository.voxforge1.org/downloads/de/Trunk/AcousticModels/), which
contains similar files like those which can be found in
grammar/model/communicator directory.

Unfortunately FS crashed without writing a core file nor logfile enries
as soon as as pizza demo trys to detect speech.

Any Ideas? Maybe someone has already working grammar/model files for
german language?


regards
helmut

Hello Helmut,

I looked at these dic files. Their content (look at all the qq's) is
quite different from the dic files supplied with freeswitch pocketsphinx.
As I remember the CMU dict file format has changed in April 2008.

Best regards
Peter

Yes you have to make sure you use the one that comes with Pocketsphinx
and not the 7.x one you download from the website. They aren't
compatible last I checked.

Maybe there is a converter somewhere?

I was thinking of just enhancing the current dict file for some german
words I need, but did not test it so far. This should be possible
without modifying the underlying grammar.

I would love to hear when you have had any progress on this.

Hi Peter,

hmmm well, I had the same idea and I tested it! Buuuuut ... you have to
make sure that the english grammar/acousticModel is able to cover all
german noises. E.g. I tried to detect "Burke", "Jan" and "Gerd". I was
able to map Burke successfully in default.dic. Otherwise I had to say
"Böhrki" ... I did the same with "Jan" - but when I tried to detect Jan
I always got Gerd (with and witout mapping ind default.dic) ... Quite
strange and not really usable for (german) customers.

But some typical software magic happened on my way:
During my tests I had somehow a configuration using the voxforge files
which was working within FS. But I can't reproduce it. I configured
serveral files at the same time and used for reloading "reloadxml" and
"reload mod_pocketsphinx" instead of rebooting FS. When it worked, FS
was able to detect "Burke", "Jan" and "Gerd" correctly without modifying
the dictionary...


Is there any manual about pocketsphinx and its config files, which can
explain how PS is working in more detail? Currently I walk with a
flashlight in the dark ...

regards
Helmut

Hello Helmut,

the 3 mentioned words are already part of the englisch standard
dictionary, so maybe this causes the problem? You may test with words
which are outside of the standard grammar files or delete the original ones?
So far I have no other documentation available. This part of
PocketSphinx is rather poorly documented. And for the FS part I've only
got some information from this mailing list.

Best regards
Peter
