Voiceless uvular trill

The voiceless uvular trill is a type of consonantal sound, used in some spoken languages. It is less common than its voiced counterpart. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʀ̥⟩, a small capital version of the Latin letter r with a ring diacritic indicating voicelessness.

Features

Features of the voiceless uvular trill:

• Its manner of articulation is trill, which means it is produced by directing air over an 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 that air is exclusively allowed to escape through the mouth.
• 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.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
