PocketSphinx phonetic feature extraction for intelligibility prediction and remediation
To compile and run, you need to install CMU PocketSphinx, e.g., on redhat/centos/fedora:
sudo yum install svn autoconf libtool automake bison python-devel swig
or, on debian/ubuntu/mint:
sudo apt-get install subversion autoconf libtool automake bison python-dev swig
then:
cd
mkdir src
cd src
mkdir ps
cd ps
svn checkout svn://svn.code.sf.net/p/cmusphinx/code/trunk/sphinxbase
cd sphinxbase
./autogen.sh
make
sudo make install
cd ..
svn checkout svn://svn.code.sf.net/p/cmusphinx/code/trunk/pocketsphinx
cd pocketsphinx
./autogen.sh
make
sudo make install
cd test/regression
./test-lm.sh
This should say, "All sub-tests passed"
cd ~/src/ps
git clone https://github.com/jsalsman/featex
cd featex
gcc -I /usr/local/include/pocketsphinx -I /usr/local/include/sphinxbase \
-I ~/src/ps/pocketsphinx/src/libpocketsphinx \
-o featex featex.c -lpocketsphinx -lsphinxbase -lm
LD_LIBRARY_PATH=/usr/local/lib ./featex we drank tea in the afternoon and watched tv
Make sure those -I include paths and the #define MODELDIR directive near the top of featex.c correctly identify where the include files, libraries, and en-us model files were actually installed. The numeric feature stream goes to standard output, and verbose debugging output goes to stderr, so in production you might likely run it with 2>/dev/null. If you don't want to prepend the LD_LIBRARY_PATH, which is necessary on redhat but not debian variants, see e.g. https://serverfault.com/a/372998
