In an attempt to replicate this voice (Thresh, LoL) https://youtu.be/EgitXjGEeQU?si=IsQo37YHf8hUcxHa
You would need some kind of reverse reverb. Of course that would add some delay to the voice since you need to reverse audio, add reverb/echo, then reverse again and play the audio.
But it would be a quite cool feature for especially evil characters.
Thanks.
