Match your voice against your choice of audio clips in a mini-gameshow! · By YeahMaybe
It would be a pretty cool idea to add "choose your character" to voice and keep the original dubbers for singleplayer and (1-3) multiplayer.
If I'm understanding the request, that's already a thing. If a pack creator tags each clip with characters, there's a list of check boxes with each character that you choose to voice in the dub. Anyone not selected will use their original audio.
