Some people requested a soundnotification when someone requests talk power.

So I did a little workaround.

Download the script and copy it to the scripts directory within your TS3 Client installation folder.

You need to change the path to the soundfile you want to play.
Code:
--the path to the soundfile (relative to the application path NOT the scripts path!)
soundfile = "./sound/voice_requested.wav"
After calling "/lua load voicerequest.lua", everything should work.
