Linguistics study on TFT accent - help needed

So, I got inspired by the thesis that got popular around a year ago about identity expression through language in TFT and wanted to make a thesis adjacent to that.

While still studying the sociology aspect of the TFT accent, I'd like to do a linguistics study on it. Basically what I mean is, what do you think marks the way TFT streamer talk as different from "normal" talking? Aside from specific terminology, do they talk differently? Use a different tone or voice; longer/shorter sentences; are there parts of words they stress more than normal...
Anything you've ever noticed is important to me, so thank you in advance to anyone who'll take the time to tell me their thoughts.

I'd also find really interesting how being exposed to the TFT accent changed the way you (watcher-non-streamer) talk/think, and if you speak with a TFT accent wether you actively tried to learn it or it happened passively through exposition.

I'd also like to study the Valorant accent, which I've recently learned it's quite prominent, but I don't play nor watch it, so if anyone wants to recommend me on who/where to start that'd be much appreciated.
(Just to put an example of what I'm looking for, I heard that part of the Valorant accent is talking slowly with a fake deep voice to mimic some streamer whose natural voice is like that)

Thanks in advance and sorry for any errors as English isn't my first language. I still haven't chosen which language I'll use for my thesis but if I choose my first language I'll still try and translate it for anyone interested.
