Are the speakers in this video speaking standard American English? [closed]

Solution 1:

I would say that they are definitely speaking with a generic American accent. Many US English speakers would characterize those two people as having no accent at all, and they certainly don't have any obvious regional accent.

As to standard American constructions and figures of speech, they are probably more formal than you'd typically find, but again there's no doubt that any US English speaker would recognize their speech as regionally neutral.

Solution 2:

I listened only briefly to those videos, but their accents are very much unmarked standard American accents, without any obvious regional markers.
