So I just subscribed to this artist on YouTube, Clint Cearley. He'd sounded North American enough until he said words ending in -ing (which sounds like "-eeng"), and accurate (which sounds like "accoorate" which isn't found in the Longman Pronunciation Dictionary). I couldn't find anything about his birthplace, not in any of his accounts on Instagram or DeviantArt or ArtStation.
Is there a place in North America where accurate is pronounced "accoorate"? Or is it just an individual anomaly (like, for example, James Rolfe on Cinemassacre who deliberately pronounces review and bury differently as "REE-view" and "BURRy").
This is a video in which he said "accoorate": https://youtu.be/9LX_MgezcK8?t=210
