Why it sounds different
Why "smooth" sounds like SMOODH.

Questions
Questions people ask about this.
Is the American pronunciation of "smooth" 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 "SMOODH" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
