>>15680895I feel bad for her, but this is why you do not roleplay as something that can fuck you over if you have ZERO control over your mouth.
If you are going to become some roleplaying vtuber - learn to rap. I'm not even joking.
If you can't rap on the spot, something sensible that is, not some dumb mumble-rap cancer, you WILL fuck up sooner or later.
Likewise stand-up comedy, ad-lib, free form construction of anything you can think of, it is an important skill in entertaining people properly. Those that can do it can stream successfully because they can keep the flow going. It ain't easy. One slip-up and you are fucked for months, if not years.
Even practice nonsensical sentence construction - you take a bunch of objects, write them down, form a story from them by filling in the rest of the scene.
This will not only improve your ability to improvise on the spot, it will improve your memory and creativity as well. Loads of people do this in comedy, acting, etc. I used it to remember a presentation several times, to write a short story for an exam.
Good luck in whatever you do.
