> "an artificial intelligence was used" this is weird phrasing? Why "an" is that normal?
Yes, it's typical syntax in the English language to separate vowels in that manner. English has lots of very little foibles like this (Y is sometimes a vowel) that you would be privy to unless you're a native speaker, so I can understand why you'd be confused, take a look here [0] for more info.
I think OP was not asking why we have the 'n' inserted, but why we are using an article at all, instead of 'an artificial intelligence' why not just 'artificial intelligence was used', after all, 'intelligence' is not normally a count noun.
Looking at OP's post history, I doubt they're confused about using 'an' vs 'a'.
In short, I think the use of 'an' here means it's a single specifically trained AI. It would not be wrong to say 'artificial intelligence was used' though, it just doesn't highlight the dedicated nature of the AI used.
Similar difference to 'Someone swapped the faces' and 'An expert swapped the faces'.
