Manually drawing GM:PlayerStartVoice?

I know about PlayerStartVoice, but the wiki example only shows a print. How would I change the position of where that the little chat box is drawn?

Copy that file, adjust the contents, put in your own gamemode/addon, chillax with overridden voice panels.

Thanks, but I don’t see anything about how it gets positioned above the player’s head.

Oh, those?
I don’t think they’re done via Lua.
Certainly they’re not done by that hook.

That sucks. Well, thank you anyways.
