Tried a build with a latest GIT, with PocketSphinx enabled, and get: Creating mod_pocketsphinx.la... /bin/sed: can't read /usr/src/freeswitch/libs/pocketsphinx-0.7/../sphinxbase/src /libsphinxbase/libsphinxbase.la: No such file or directory quiet_libtool: link: `/usr/src/freeswitch/libs/pocketsphinx-0.7/../sphinxbase/sr c/libsphinxbase/libsphinxbase.la' is not a valid libtool archive cat: .libs/mod_pocketsphinx.log: No such make[5]: *** [mod_pocketsphinx.la] Error 1 I don't pretend to fully understand the build system, but the makefile seems to be trying to go to libs/sphinxbase for files, when that directory doesn't exist. The currently downloaded version of sphinxbase has the version appended to the directory name, as in sphinxbase-0.7. The Sphinx readme warns that the root should be named sphinxbase. I did: ln -s sphinxbase-0.7 sphinxbase and the build finished without problems. PocketSphinx works fine on a hardware phone using ULAW, but, when I use a softphone with 16Khz Speex, it doesn't. Instead, I get this 2011-07-27 21:43:14.651803 [WARNING] mod_pocketsphinx.c:147 Can't open speech model /usr/local/freeswitch/grammar/model/wsj1. The only item in the model directory is communicator. I thought wsj1 was the old model. What in Freeswitch would try to use wsj1 over communicator based on the codec/rate? The mod_pocketsphinx wiki page says that 16Khz is a supported sampling rate, so I'm guessing that there is a special reason why Speex doesn't work, or else that this is a bug. Bryan
