ShortVowel contrast
Long O vs Short O Minimal Pairs
/oʊ/ and /ɑ/ pronunciation, listening, and reading practice
Long O has a noticeable glide and lip rounding. The common North American short O is open, low, and does not use that glide.
Produce both sounds accurately
What changes in the mouth?
Long O
Begin at mid-back and glide toward rounded lips.
Short O
Open the jaw; keep the tongue low-back and the lips relaxed in North American English.
Accuracy note: Short O varies by accent. This page uses common North American /ɑ/; British learners may use /ɒ/.
