Features of the voiceless bilabially post-trilled dental stop:
Its
manner of articulation is
trill, which means it is produced by directing air over an articulator so that it vibrates.
It has two places of articulation:
The stop is
dental, which means it is articulated with either the tip or the blade of the tongue at the upper
teeth, termed respectively apical and laminal.
The trill is
bilabial, which means it is articulated with both 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.
