I realize sir that we need a very light weight model for XO. And
hence, I was contemplating using Julius instead of sphinx ( as I
mentioned in my first mail to the list)

Julius is written in C. It might help solving some of the problems we
face with Sphinx.

As far as the language models are concerned, Julius is currently
developed well for Japanese and their homepage claims that  VoxForge
is working on developing it for other languages.

Repeating for easy reference:

http://sourceforge.jp/projects/julius
http://julius.sourceforge.jp/en_index.php (View the About Models section)

I'll try my best :)
