How to pronounce “duo”
Duo is pronounced /ˈduːoʊ/. It has 2 syllables, and the beat falls on the first one — duː. Below: the syllable split, native audio in both accents, the mistake people actually make with this word, and every individual sound in it explained.
Syllables and stress
Split it into 2 beats. The highlighted syllable is the strong one: say it louder, longer and a touch higher in pitch, and let the others fall away. English is a stress-timed language, so getting duː in the right place matters more to a listener than getting every vowel perfect.
Stress pattern Oo — capital letters mark the stressed beats.
