kaldi/egs/README.txt

This directory contains example scripts that demonstrate how to 
use Kaldi.  Each subdirectory corresponds to a corpus that we have
example scripts for.

Note: we now have some scripts using free data, including voxforge,
vystadial_{cz,en} and yesno.  Most of the others are available from
the Linguistic Data Consortium (LDC), which requires money (unless you
have a membership).

If you have an LDC membership, probably rm/s5 or wsj/s5 should be your first
choice to try out the scripts.
