Features of the voiceless uvular trill:
Its manner of articulation is trill, which means it is produced by directing air over the articulator so that it vibrates.
Its place of articulation is uvular, which means it is articulated with the back of the tongue (the dorsum) at the uvula.
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 lungs and diaphragm, as in most sounds.
Features of the voiceless uvular raised non-sonorant trill:
Its manner of articulation is fricative trill, which means it is a non-sibilant fricative and a trill pronounced simultaneously.
Its place of articulation is uvular, which means it is articulated with the back of the tongue (the dorsum) at the uvula.
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.
