This is a set of Python wrappers for Kaldi input-output classes.
It allows you to do e.g.:
In [1]: import kaldi_io
In [2]: feat_reader = kaldi_io.SequentialBaseFloatMatrixReader('scp:./mfcc/raw_mfcc_test.1.scp')
In [3]: next(feat_reader)
Out[3]:

The software should build against a recent version of Kaldi:
- Install boos python. For anaconda linix run
conda install boost - Build and install Kaldi, make sure to use
configure --shared - Build kaldi python:
KALDI_ROOT=path_to_kaldi make - Configure PYTHONPATH:
export PYTHONPATH=`pwd`/kaldi-python
