I thought I might share a small phonetic game/challenge with you. All 3 individuals in the attached clips were born and raised in the same country and speak the same native language. Can you tell, based on the peculiarities of their English pronunciation, what language it is?
The first two are British. I know regional dialects vary, but I can’t identify one from the other.
The third one sounds like an American, but has a very “professional” dialect. Some people will talk like this for recordings, but since you said she’s from the same country as the other ones, I’m guessing she learned her American accent from media, and not from regular conversations.
