I got that in the console when i start the game :

KeyValues Error: RecursiveLoadFromBuffer: got EOF instead of keyname in file scripts/RadialMenu.txt
RadialMenu, B2,Survivor,Alive, NorthEast,
KeyValues Error: RecursiveLoadFromBuffer: got EOF instead of keyname in file scripts/RadialMenu.txt
RadialMenu, B2,Survivor,Alive, (*NorthEast*),
KeyValues Error: RecursiveLoadFromBuffer: got EOF instead of keyname in file scripts/RadialMenu.txt
RadialMenu, (*B2,Survivor,Alive*), (*NorthEast*),


EDIT : Ok i found what was the problem, forgot to put one voice line for bill and also a " at the end of a line.

So you actually did break the vocalizer! :) That's why it's best to use some advanced text editor, like Notepad++ or similar, to avoid this kind of situations.

By the way, I wanted to make my vocalizer multilingual a long time ago. But then I learned from Valve's documentation that Workshop addons can't be made multilingual, ie. to automatically select the language to the language of the game. I even wrote Valve a question about this, but ofcourse never got the reply from them...

I wonder how do you manage to know what is the vocalize command for a sound in particular, name doesn't seem to correspond to the files in the survivor voice folder.

No, you actually vocalize concept names. One has to know a lot about game's response system, game sounds, scenes, talker, criteria, concepts, responses and rules to be able to make a vocalizer like mine. I can freely say that very few people besides me and authors of modified talker addons (excluding Valve stuff) know how the response system works and how broken it is in some places. ;)
