Good to hear. I am trying from last week to learn how was it designed. When are you going to commit the changes? In days in weeks? I would like to use the new code to build upon. I would like to run some experiments first, than I need to build a python wrapper (my project requirements). Currently I am finishing a python wrapper for the compute-mfcc-featscc , gmm-latgen-faster.cc and lattice-best-path.cc using https://cffi.readthedocs.org/en/release-0.6/. Basically I am trying to build shared library containing functionality of the compute-mfcc-featscc , gmm-latgen-faster.cc and lattice-best-path.cc. Than the rest is very easy using python-cffi ( https://cffi.readthedocs.org/en/release-0.6/). I guess there is no plan to distribute Kaldi as shared library, right?
