That is by far the strangest accent analysis and such a strange focus of a topic for a video. I can hear the difference in her sentence structure and a bit more of an accent, but that has probably a lot more to do with who she is talking with on a regular basis or what part of the world she is actively living in when these videos were taken than her actually faking anything. For example, my ex is viet and after being around her family regularly for even just a few months I was occasionally using broken english in conversations without realizing it because that's how her family would converse with me. Ironically broken english was almost always easier for someone who has ESL to understand.
Anyways...again really odd topic. How the fuck people come up with the time to make a video like that is just beyond my understanding.
