Downloading and installing Kaldi

Dowloading Kaldi

You first need to install Subversion (SVN). The most current version of Kaldi can be downloaded by typing into a shell:

    svn co https://kaldi.svn.sourceforge.net/svnroot/kaldi/trunk kaldi-trunk
  

A branch corresponding to version 1 of Kaldi may be obtained at:

    svn co https://kaldi.svn.sourceforge.net/svnroot/kaldi/branches/1 kaldi-1
  

This may be more stable than the ``trunk'' version, which may occassionally be broken by new changes. However, at the present time we recommend to use the ``trunk'', as it has a lot more features than kaldi-1 (e.g. discriminative training), and nicer scripts. If you want to get updates and bug fixes you can go to some checked-out directory, and type

    svn update
  

If "svn update" prints out scary looking messages about conflicts (caused by you changing parts of files that were later modified centrally), you may have to resolve the conflicts; for that, we recommend that you read about how svn works.

Installing Kaldi

The top-level installation instructions are in the file INSTALL. For Windows, there are separate instructions in windows/INSTALL. See also The build process (how Kaldi is compiled) which explains how the build process works internally.

The example scripts are in egs/
