Voiceless linguolabial affricate

A voiceless linguolabial affricate is a rare type of consonantal sound, used in disordered speech. It is not in English.

• The phonation is voiceless. This means that this sound is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
• The place of articulation (where the sound is produced) is linguolabial. This means that this sound is produced with the tongue against the upper lip.
• The manner of articulation (how the sound is produced) is affricate. This means that this sound is produced by first stopping the air flowing from the mouth, then allowing air flow through a constricted channel at the place this sound is produced, to make turbulence.

It is unlikely that it occurs in disordered speech.
