The consonants f and v represent labiodental fricative consonants, respectively voiceless and voiced.
F and v are represented in written and spoken English like this:
f: face, five, benefit, self, of;
v: vanilla, vase, seven, avocado.
The letters f and v are labiodental fricative consonants that are pronounced when the teeth come in contact with the lower lip. Then, the amount of air released by the mouth is restricted and a friction sound is produced.
They differentiate because:
- f is voiceless, so the vocal cords do not vibrate during the articulation of the consonant;
- v is voiced, the vocal cords vibrate during the articulation of the consonant.
