Vocal folds: vibrating

TongueTeethUvula

Simplified human pronunciation. The small uvula hangs from the palate; it is not the vocal folds. The wave indicates voicing.

The mouth starts slightly open. Movement is slowed for observation; the synthetic sound plays once at its original speed. Pause holds the current mouth shape; reset returns to the relaxed position. The panda is a symbolic teaching aid for human pronunciation, not animal anatomy.

What your mouth is doing

American /ɝ/ blends vowel and r into one sound: the tongue pulls back or bunches while the lips round slightly. Unstressed /ɚ/, as in teacher, is the weaker form. British /ɜː/ is a long central vowel with no r sound. In unstressed endings such as teacher, British English uses plain /ə/.

Comparing with Mandarin and Spanish

Many spellings share it: ir, ur, er, ear and or after w. Reading the letter order literally is misleading, so work has this vowel and not the vowel in walk.

Spanish has no such vowel, and speakers may read the letters as er or ir. Mandarin er can hint at the American tongue shape, but it is not the same sound, and British /ɜː/ has no r at all.

Build the sound, step by step

  1. For American English, pull the tongue back with its tip free, and start your voice. For British English, relax a central vowel.
  2. Hold the sound steadily, with no separate vowel before it.
  3. Say bird, learn and work, then teacher with the weak form at the end.

What to watch for

  • Reading or as /ɔ/ turns work toward walk. After w, this spelling usually gives the bird vowel.
  • Splitting the vowel and r into two beats adds a syllable. Keep them together.

Hear the difference in your own voice

Compare work and walk, then bird and bud. For work and bird, use the r-colored or long central vowel. For walk, round the lips; for bud, make a short central vowel.
