The /ɜː/ sound — er as in bird

In short

/ɜː/ is a long open-mid central vowel — the vowel you hear in bird, work, learn. Like every diphthong, the glide between two positions IS the sound. Below: exactly how to position your mouth, audio you can copy, the mistakes learners actually make, and drills to fix them.

How to pronounce /ɜː/

  1. 1Keep your tongue flat in the centre of your mouth — not forward, not back.
  2. 2Relax your lips completely.
  3. 3Hold a long, steady 'errr' with no r sound at the end (British).

Sounds like: a long thinking sound — 'errr' — with a relaxed mouth

/ɜː/ in words — with audio

Listen, then copy. The slow (turtle) version exaggerates the mouth movement.

  • bird/bɜːd/ · sound is medial
  • work/wɜːk/ · sound is medial
  • learn/lɜːn/ · sound is medial
  • first/fɜːst/ · sound is medial
  • turn/tɜːn/ · sound is medial
  • word/wɜːd/ · sound is medial

The mistake almost everyone makes

Adding a strong r or replacing it with /ɔː/ or /ɑː/ so 'work' sounds like 'walk' and 'heard' like 'hard'. In RP there is no r — just the long central vowel.

Who struggles with this sound:

  • Russian speakers — /ɜː/ has no Russian equivalent — 'bird', 'work' come out as 'byord'/'vork'
  • Turkish speakers — /ɜː/ vs /ɔː/ confusion — 'bird'/'board', 'work'/'walk'

Spellings of /ɜː/

These letter patterns commonly spell /ɜː/: ir er ur or ear. English spelling is unreliable — trust the IPA, not the letters.

British vs American: American English uses an r-coloured vowel /ɝ/ — the r is clearly pronounced throughout ('bird' = /bɝd/). Both are correct; pick one and be consistent.
