The voiceless bilabial trill is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʙ̥⟩
This sound is typologically extremely rare. It occurs in languages such as Pará Arára and Sercquiais.
Features
Features of the bilabial 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 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.
- Because the sound is not produced with airflow over the tongue, the central–lateral dichotomy does not apply.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.
