bottle butter

when i say bottle a native speaker thinks its butter
whats different between their accents??????????
only one vowel differs and rest is same isnt it

And in the dialect here in Milwaukee, the difference is even greater, with:

"bottle" [ˈb̥aɾ̥ɯː] or [ˈb̥aɯ̯]
"butter" [ˈb̥ʌɾ̥ʁ̩ː] [ˈb̥ʌːʁ]

Stressed vowes: bottle has /A/ and butter /@/ for me,
L vs R, I guess you're Japanese

I'm Korean, not Japanese....

"Bottle" is more like [바를] while "butter" is more like [버러ㄹ].

"endic.naver.com" used to have decent 발음듣기 service but somehow their pronunciation is not native-like anymore.
