Avoiceless epiglottal affricate ([ʡ͡ʜ] inIPA) is a rareaffricate consonant that is initiated as anepiglottal stop[ʡ] and released as avoiceless epiglottal fricative[ʜ]. It has not been reported to occurphonemically in any language except in the Hydaburg dialect of the Haida language.

Features of a voiceless epiglottal affricate:

• Itsmanner of articulation isaffricate, 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.
• Itsplace of articulation isepiglottal, which means it is articulated with thearyepiglottic folds against theepiglottis.
• Itsphonation 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 anoral consonant, which means that air is not allowed to escape through the nose.
• It is acentral consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
• Itsairstream mechanism ispulmonic, which means it is articulated by pushing air only with theintercostal muscles andabdominal muscles, as in most sounds.
