The developers of Sphinx have set up a excellent documentation:

http://cmusphinx.sourceforge.net/sphinx4/  (Creating and using Acoustic Model Package)

Hi dasinen,

Do you mean you are looking for a procedure to adapt the VoxForge acoustic model to your voice?

Which speech recognition engine are you using?

We have instructions for creating an acoustic model for Julius on the VoxForge site, and CMU's Robust group has instructions for creating acoustic models for the Sphinx group speech recognition engines.

I guess I should have read the subject line before replying... :)

You are looking for the Robust Group tutorial.

Hi rdus,

You might want to look at how the WAMI toolkit was implemented.
