import speech files

I also mentioned this in the bug-fix channel on the discord. 
It seems like the import speech files function is not working. 

 "successfully imported 0 speech files" it says. 

This seems to be an already known bug. Is there a way to fix it? 

If not what's the best way to import my speech files? Every single one manually? Or is there a a Lua Script I could use? (Lua Noob here)

Thanks in advance!
