Voiceless epiglottal trill

The voiceless epiglottal or pharyngeal trill, also analyzed as a fricative, is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʜ⟩, and the equivalent X-SAMPA symbol is H\.

Features

Features of the voiceless epiglottal trill/fricative:

  • 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 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.
  • 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.
