I 've found what's wong with the sounds in "Spaxs Speech Fix". It seems that the torpedo announcements in a US Submarine are performed by a different officer than in German U-boat. That means that the names of the german files are not the same with names of the English ones and so the sounds like "Torpedo Impact" "Firing Tube One" allthough there are in the speech pack are not working. I am in the proccess of making a small fix that hopefully will do the trick.
Nevertheless I am frustrated that the german voices weren't included in the add-on.
And I am pretty sure that that's happened because the whole thing would be more than one cd....which means additional costs for Ubi ...
- Edit - Does anyone know if the german install of SH4 have the complete set of voices in german? It would be much easier to take the sounds from there....but I don't want to uninstall-reinstall just to see that the sounds are not completely ok in the german install as well
