Re: [Kaldi-developers] python wrappers for Kaldi

[Jan C. <jan...@gm...>]

Hello Dan,

thank you for the comments. I tried to make it in the Kaldi spirit, 
consistency is important. Of course, the scripts can be removed and 
replaced with some more useful examples. I don't have too much 
experience with bridging Python to C++, so any critique on the wrappers 
and the approach taken is welcome.
