I’m pretty sure this isn’t possible but, even so itd be a fun idea to discuss.
Basically a voice changer not for the client himself, but for people he chooses. Whiny little kid being annoying? Flip it on and his voice, atleast to you, is now deeper. Now its a whiny adult, but no more ear splitting noises . Hell maybe just a clientsided mute button. Yeah better off that way.
