In short

/f/ is a voiceless labiodental fricative — the consonant you hear in fan, coffee, life. It is voiceless: only air, no vocal-cord vibration. Below: exactly how to position your mouth, audio you can copy, the mistakes learners actually make, and drills to fix them.

How to pronounce /f/

  1. 1Touch your top teeth to your bottom lip.
  2. 2Blow air through the gap — a soft continuous hiss.
  3. 3No voice: fan, coffee, life.

/f/ in words — with audio

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

  • fan/fæn/ · sound is initial
  • coffee/ˈkɒfi/ · sound is medial
  • life/laɪf/ · sound is final
  • difficult/ˈdɪfɪkəlt/ · sound is medial
  • future/ˈfjuːtʃə/ · sound is initial

The mistake almost everyone makes

Using both lips instead of teeth-on-lip so f sounds like /p/ or a soft h — listeners hear 'pood' or 'hood' for 'food'.

Who struggles with this sound:

  • Bengali speakers — /f/ hardens to an aspirated p — 'fan' sounds close to 'pan'
  • Korean speakers — no /f/ in Korean — 'coffee' → 'copi', 'fine' → 'pine'
