Earlier quoted context omitted.
Then you don't pronounce it well :D The link you gave me looks like someone with a strong English accent trying to pronounce French (which make sense for an AI)
No, it's someone speaking the anglicised pronunciation which is correct in English just like for the other 1000s of borrowed French words in English. Though you'll be happy to know that where I grew up in Texas, everyone tried to pronounce "croissant" the French way when (and only when) ordering one at a deli counter. But we weren't far from Paris, Texas.
What I said is incorrect, is the parent poster saying it sounds closer to "é" than the sound of "best".
If you can't tell the difference, too bad for you, but that doesn't make you right.
"è" (or "et" in French) is pronounced /ɛ/. Wikipedia will confirm that this is indeed the same sound as in "best" (/ˈbɛst/). https://en.m.wiktionary.org/wiki/best
"é" is not the same sound. It's pronounced /e/ like in "fiancée" (/fiˈɑnseɪ/) https://en.m.wiktionary.org/wiki/fianc%C3%A9e
> anglicised pronunciation which is correct in English
All the links I have posted are for the anglicised version of the French words.
