f

Lower case f

Voiceless labiodental fricative.

When we pronounce this sound, the lower lip, the active articulator, approximates to the edge of the upper front teeth, the passive articulator. The velum is in its raised position. So, the lung air cannot go out through the nasal cavity. Friction is produced when the lung air goes out through the passage formed by the two articulators. The vocal folds do not vibrate during the production of this sound.

Pronunciation

The soft palate is in its raised position and the vocal folds do not vibrate. The lower lip touches the upper front teeth forming a small passage through the pulmonic air stream escapes producing friction.
