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.

Allophone of

. In the source itself, the meaning of
/q??/
is unclear, but
/q??/
seems to be a voiceless labial?uvular stop with significant lowering and a strong release. Contrasts /k?p, q??, ??b, ???/.
