Re: [Kaldi-users] Committed change to build setup

[Mailing l. u. f. U. C. a. U. <kal...@li...>]

Hi all,

I would like to thank you for implementing the kaldi compilation to shared
libraries and merging them to trunk.
It allows me to build python bindings easily for Kaldi decoders using cffi
library (http://cffi.readthedocs.org/en/latest/.)

So far, I managed to setup decoding example, which is based on Voxforge
Online demo.
All the C++ Kaldi functionality is called from Python via cffi.

In order to try it, follow the steps below:

# 1.
svn checkout svn+ssh://oplatek@svn.code.sf.net/p/kaldi/code/sandbox/oplatek2
# Change your username

# 2. INSTALL portaudio and cffi.
# For portaudio:
cd oplatek2/tools; ./install_portaudio.sh
# For cffi you have options a) or b)
# a) Go to http://cffi.readthedocs.org/en/latest/ and following the
instructions install the cffi system wide! (Recommended)
#    Read the Requirements section!
# b) Go to oplatek2/tools and install cffi locally by
using install_cffi.sh.
# After a successful installation the script prompts you to add the
installation directory to PYTHONPATH.
# Do it, it will be needed in step 7.

# 3.
cd oplatek2/src

# 4. Configure it with --shared flag
 ./configure --fst-root=`pwd`/../tools/openfst --shared

# 5. Build Kaldi. Clean it and tested to be sure that, it is not corrupted.
make clean; make depend && make ext_depend && make && make ext && make test
&& make ext_test

# 6. change to the directory with the example
cd python-kaldi-decoding/pykaldi/binutils/

# 7. run make test, it should compile and downloaded everything needed
make test

# 8. Check the results! My results for python-online-wav-gmm-decode-faster
are:

python-compute-wer --config=configs/wer.config ark:work/reference.txt
ark:work/online.trans.compact
%WER 15.03 [ 55 / 366, 6 ins, 15 del, 34 sub ]
%SER 100.00 [ 3 / 3 ]
Scored 3 sentences, 0 not present in hyp.


Any feedback is welcome!

I am committing to https://github.com/oplatek/pykaldi .
To svn.code.sf.net/p/kaldi/code/sandbox/oplatek2 I will commit just major
updates which should not break things.

Cheers,

Ondra
