Minimal Pairs Duel

About Minimal Pairs Duel

Minimal Pairs Duel is a free English pronunciation game built on the oldest and most effective idea in phonetics: two words that differ by exactly one sound. You hear one word spoken — ship or sheep, light or right, vest or west — and you tap the one you actually heard. Twelve questions make a round, and because the game rotates round-robin through its sound groups, every question of the day tests a different contrast. One round is a full sweep of your ear rather than twelve repeats of the same problem.

The bank holds more than 230 pairs across 24 sound contrasts, and each group comes with a one-line articulation tip that tells you how to make the sound with your mouth instead of describing it in jargon: for /v/ against /w/, touch your top teeth to your bottom lip and buzz, and for /w/ round both lips and keep the teeth away; for /s/ against /z/ the tongue never moves — /s/ is quiet air and /z/ buzzes, so put a hand on your throat and feel it. Every word in the bank is a common A1 to B2 word, so you are never guessing at vocabulary you have not met.

Three of the groups exist specifically for the mistakes Vietnamese learners make most often. The /ð/ versus /d/ group separates they from day, then from den, though from dough and other from udder — the classic "dis, dat, dose" habit — and its tip is the whole fix: put the tongue tip between the teeth and switch your voice on. The -ed group contrasts worked /wɜːkt/ with wanted /ˈwɒntɪd/ and asked /ɑːskt/ with added /ˈædɪd/, drilling the rule that -ed is only an extra syllable /ɪd/ after a /t/ or /d/ sound, /t/ after other voiceless sounds, and /d/ after voiced ones. The final consonant cluster group pits desks against desk, months against month, texts against text and sixth against six, because dropping the last consonant is the number one reason a listener hears the wrong tense or the wrong number.

Feedback is immediate and phonetic. You can replay the word as many times as you like before you answer; the moment you choose, both options show their IPA, the right word is highlighted, and the pair is played back-to-back so you hear the contrast in isolation. A streak multiplier keeps the pressure honest — 100 points a question, doubled after three correct in a row and tripled after six — and the end-of-round recap lists every pair with IPA and a 🔊 replay on each word. Play the daily duel, or switch to free practice for unlimited random rounds. It is free, it works on a phone, and there is no sign-up.
