The voiceless labial–uvular plosive is a type of consonantal sound used in some spoken languages. It is a [q] and [p] pronounced simultaneously. The symbol in the International Phonetic Alphabet that represents this sound is ⟨q͡p⟩.^[1]^[2]^[3]

Features

The features of the voiceless labial–uvular plosive are:

Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive.
Its place of articulation is labial–uvular, which means that it is simultaneously articulated with the tongue against the uvula and the lips.
Its phonation is voiceless, which means it 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.
It is an oral consonant, which means air is allowed to escape through the mouth only.
It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
