[Freeswitch-users] pocketsphinx

[Peter P GMX]

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
