You seem to speak broadly something similar to General American (Midwestern/Californian/Hollywood), but there are some differences, so I'm assuming you're from somewhere a little removed from the core of General American. Maybe somewhere in the northeast (Pennsylvania or beyond) but not with a distinctive New England accent, so probably not Boston for example (maybe Maine?), or my first thought was somewhere bordering on the south, somewhere in the middle of the US like Ohio near Kentucky, or something like that.
To be clear, I'm not a dialectologist, so for more on this I'd need to compare some of your pronunciations to maps. You can do that though. This is one good website:
www.dialectsarchive.comThere are also, of course, many 'accent tag' videos on Youtube to compare to your own pronunciation.
The reason I find it hard to locate your speech is that you pronounce many words like I do (I'm from California), but some differently. "Aluminium" for example was the oddest, although maybe you're just reading that as a spelling pronunciation (vs.
aluminum) or it could just be a word you learned differently rather than a marker of your regional dialect. The only other feature I notice is that you often have nasalized vowels, but it doesn't seem particularly regional to me, and maybe that's just your personal pronunciation rather than a regional feature.
A more rural Midwestern accent would also have some more consistent forms like "ont" (for aunt) and "ruff" (for roof), but you only pronounced
roof like that. So it's hard to say. I wouldn't be at all surprised if you lived in a big city where some pronunciations are mixing and you are exposed to a lot of different pronunciations, and if you have moved around some. Most "pure" dialects are recorded by older speakers living in rural areas in order to exaggerate differences. In reality, it's all mixed a bit more than that, so you're probably not an exception.
Listening to all of it again, a few words stood out this time: caught (very clearly NOT a merger with the "cot" vowel!), and "coupon" (an unusual pronunciation for my ears). So I would say probably something eastern, still a little removed (but not completely removed) from General American, and I'd say something like West Virginia, or Vermont, maybe Maine. A border area of some sort, I believe. And I'm not sure all of your pronunciations are consistent (maybe learned from a parent from somewhere else, etc., or if you've moved around) so one might be throwing me off from your regional accent. Anyway, that's just my guess, and as I said I'm not a dialectologist and haven't spent much time comparing dialects from the Eastern US.
