Unit 2.1

Sound: PH


The digraph ph is a labiodental fricative voiceless sound.


Ph is a group of letters that make one sound, what we call a digraph. In this case, the sound is a labiodental fricative.

Ph is represented in written and spoken English like this:

Uppercase Lowercase Phonetics
PH ph /f/


ph: phone, photo, alphabet, elephant.


Ph is a labiodental fricative sound, pronounced when the uper teeth come in contact with the lower lip, restricting the flow of air to produce a friction sound.

  • Ph is voiceless sound, so the vocal cords do not vibrate during the articulation of the digraph.

The digraph ph has the same characteristics as the letter f, as it represents the same sound.
