Features

Features of the voiceless epiglottal trill/fricative:

Its manner of articulation is trill, which means it is produced by directing air over an articulator so that it vibrates.
Its
epiglottal, which means it is articulated with the aryepiglottic folds against the epiglottis
.

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
intercostal muscles and abdominal muscles
, as in most sounds.
