If you have any of the viseme files, you should be able to
substitute a few names to fit the mil horse.

In other words, just fill in the proper internal names for the
parts, then take all the sounds and refer them to the
main open mouth morph.    It's probably mouthOpen but
might be LipsOpen or something else.
