Q: How is the unstressed American ER-vowel different from a British one?

British speakers drop the R after a vowel, so mother ends with a soft uh shape. Americans keep the R and let it dominate the vowel: the tongue pulls back and the vowel and R fuse into one continuous shape. There's no separate vowel here. The R-coloring runs from the start of the syllable through to the end, and that fusion is one of the clearest tells between an American and a British accent.

Q: Why do my American English words still sound foreign even when I pronounce a clear R?

Often it's because the R is being added after the vowel rather than blended with it. Speakers from rolled-R languages tend to pronounce a clean vowel and then a separate trill or tap, which sounds either clipped (Spanish, Italian) or over-articulated (Russian) to American ears. The fix is to blur the two: let the tongue start pulling back before the vowel even begins, and treat them as a single shape.

Accepted Answer

British speakers drop the R after a vowel, so mother ends with a soft uh shape. Americans keep the R and let it dominate the vowel: the tongue pulls back and the vowel and R fuse into one continuous shape. There's no separate vowel here. The R-coloring runs from the start of the syllable through to the end, and that fusion is one of the clearest tells between an American and a British accent.

Question 2

Where does the R sound 'come from' in the American /ər/ vowel?

Accepted Answer

Because the schwa is completely absorbed by the R, the tongue is already pulled back into the R position as the syllable begins. The R-coloring is there from the very start rather than growing in at the end. If you start with a pure vowel and then add an R, you'll sound over-enunciated. The unstressed American R-vowel is one fused shape from the moment the syllable starts.
