Vow

Pronounce it as /vaʊ/. Start with an open back vowel /a/ and glide quickly to /ʊ/ to form the diphthong /aɪ/ variant? Wait—correct diphthong is /aʊ/: lips start rounded, jaw drops slightly, then close toward a rounded, near-close near-back position. Stress is on the word itself as a monosyllable. Listen to native audio [use your preferred audio resource].

Common mistakes include treating it as a simple /oʊ/ like 'go' or shortening the vowel to a pure /a/; many learners also misposition lip rounding, making it a flatter sound. Correct it by producing a distinct /a/ starting point, then glide to /ʊ/ with rounded lips. Keep it clean as a single, smooth /aʊ/ glide without adding extra consonants at the end.

In US/UK/AU, the core /aʊ/ diphthong is similar, but quality shifts slightly. US often has a slightly higher starting tongue position and more open jaw, UK can have a more centralized /a/ with less lip rounding at onset, Australian tends toward a quicker glide with a slightly reduced duration of the second element. All retain the single-syllable rhythm. IPA: US /vaʊ/, UK /vaʊ/, AU /vaʊ/

The challenge is the tight, quick diphthong /aʊ/ that requires fast tongue movement from a low-to-mid front position to a high back position, plus precise lip rounding. Misplacing the tongue or flattening the glide makes it sound like /voʊ/ or /vo/. Practice with slowed, exaggerated movement to feel the glide: start with /a/, then slide to /ʊ/ while rounding the lips.

Is there a phonetic distinction when 'vow' is followed by a consonant cluster or in connected speech? In standard careful speech, /vaʊ/ remains a tight, swift diphthong; in rapid connected speech, you may hear a reduced vowel or a mild vowel lengthening before a consonant, but typically the diphthong remains recognizable as /aʊ/ with only minor vowel duration variance.
