[Freeswitch-users] Problems with Mod_openMRCP

Tue Dec 2 08:43:44 PST 2008

from build root:

svn co -r8809
http://svn.freeswitch.org/svn/freeswitch/trunk/src/mod/asr_tts/mod_lumenvoxsrc/mod/asr_tts/mod_lumenvox

They did seem to express an interest in granting some dev licenses when they
realized we took the code out of tree but I have not actually dealt with the
issue yet because I have been overwhelmed.

I don't know if this code works anymore with the latest revision of the api
but there it is.
