Common mistakes

Releasing the final consonant with a puff of air.

In "curb", the "b" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.

Pronouncing the "R" too clearly.

Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.

Questions

Questions people ask about this.

How do I pronounce the R in "curb"?

Americans use a relaxed retroflex R: the tongue curls back rather than rolling, and the R is one continuous sound with the vowel before it — not two separate sounds. Don't try to pronounce a separate vowel followed by a separate R. Treat them as a single shape.

Is the American pronunciation of "curb" different from British English?

American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "KURB" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
