battle speeches no sound + text

I didn't find anybody else with this problem, yet.

My battle speeches show the animation, but no sound and no text. All other sounds work fine.

I am using 1.4.4 fresh install and Galoopers voice mod, though I also had this problem without it and with a previous installation.

Can anybody point me to the files which are important for this speeches.
So I can start finding the problem myself maybe.
Maybe some files are missing.

Just solved a similar problem with a missing file as I used the torrent and no idea how such a file can go missing.

Nobody here who can just point me to the responsible files? Very likely I can try to sort out this problem myself then.
