Custom speech files from Armageddon to Reloaded?

[Tarmo]

I noticed that in Reloaded the speech files are in forms like .xsb/.xgs/.xwb - and in Armageddon they were just regular .WAV-files. I have a bunch of custom speech files from the Armageddon version and I was just wondering is there any easy way to add them to Reloaded.

Drag and drop seems to out of the question since the file forms are out of this world. And recording all again is not an option. So has anyone figured out how to handle this?
