    /ɔː/ vs /ɜː/: walk vs work

    In short

    The rounded back /ɔː/ and the neutral central /ɜː/ separate walk/work, born/burn and warm/worm, a pair of long vowels that learners very often collapse into one. This contrast carries a MEDIUM functional load, the contrast separates a fair number of word pairs, so it is worth systematic practice once the high-load contrasts are stable.

    How to hear (and make) the difference

    /ɔː/ has firm lip rounding; /ɜː/ has NONE; lips completely relaxed, tongue flat in the centre. If your lips are round on 'work', it will come out as 'walk'.

    Most challenging for Spanish, Portuguese, Vietnamese, Bengali, Arabic speakers.
