Hello,
I spent a few days working on my problem. I played around with
voxforge's data, read some of the train docs of CMU, and debugged the
sphinxbase, pocketsphinx and mod_pocketsphinx.
Results:
- -I found a way to use the voxforge data as training data for creation of
a german language corpus.
- -I enabled the logging of pocketsphinx to stderr (Dirty, but easy way to
see what went wrong when FS loads grammar, mdef, etc and simply stopped.
Very helpful!
- -I had to add a "dictcase" parameter to pocketsphinx.conf.xml resp
mod_pocketsphinx.c to allow case sensitive dictionaries (like the german
dictionary from voxforge).
FS starts up with german language model and detects the words as
expected. But it's not so reliable as I want to ... I guess this is
caused by the very small amount of training audio data. I used 4000 of
19000 audio files provided by voxforge due to the reason that voyforge's
training fileid-list contains only 4000 files ... I have to create new
fileid-list and transcription-lists containing all audio I have
downloaded from voxforge.
Quite complex the whole thing ...
regards
helmut
