Third-party:SpeechRecognition:cmusphinx3 old version
With some old version of sphinx3_decode, there was problem with x86_64 version and utf8 language model, failing in segmentation fault.
If you face this situation, it is recommended to compile as ix86 even on x86_64 bits OS using specific options.
To begin, you need to prepare your computer for compiling source code.
Then, you can get the source code:
Important: you should checkout sphinxbase, sphinx3 and SphinxTrain into the same root directory, such a way, the configuration system will automagically find sphinxbase headers and libraries svn co https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/sphinxbase svn co https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/sphinx3 svn co https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/SphinxTrain
WARNING: it seems using a x86_64 version of sphinx3_decode with utf8 language model fails in segmentation fault (no problem with ix86).
So it is recommended to compile as ix86 even on x86_64 bits OS using specific options
For that, you need additional packages.
sphinxbase compilation instructions (libraries will be available in src/libsphinxbase/.libs):
cd sphinxbase ./autogen.sh ./configure CFLAGS="-m32" LDFLAGS="-m32 -L/usr/lib" --without-python make -s
sphinx3 compilation instructions (binaries will be available in src/programs):
WARNING: to have case sensitive dictionary (which is requested with LIUM models), you must patch the source code
cd ../sphinx3 patch -N -p1 -s src/libs3decoder/libdict/dict.c < HEMERA_TP_PATH/speechRecognition/misc/sphinx3_caseSensitive.patch ./autogen.sh ./configure CFLAGS="-m32" LDFLAGS="-m32 -L/usr/lib" make -s
-> check/update the hemera.core.speechRecognition.tool.* configuration elements
SphinxTrain compilation instructions:
cd ../SphinxTrain ./configure CFLAGS="-m32" LDFLAGS="-m32 -L/usr/lib" make -s cp bin*/wave2feat HEMERA_TP_PATH/speechRecognition/bin
-> check/update the hemera.core.speechRecognition.soundFeatureCreator.* configuration elements
