Voiceless epiglottal affricate

A voiceless epiglottal affricate ([ʡ͡ʜ] in IPA) is a rare affricate consonant that is initiated as an epiglottal stop [ʡ] and released as a voiceless epiglottal fricative [ʜ]. It has not been reported to occur phonemically in any language except in the Hydaburg dialect of the Haida language.

Features of a voiceless epiglottal affricate:

• Its manner of articulation is affricate, which means it is produced by first stopping the airflow entirely, then allowing air flow through a constricted channel at the place of articulation, causing turbulence.
• 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 that air is not allowed to escape through the nose.
• It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.
