Avoiceless glottal affricate is a type ofconsonantal sound, used in somespokenlanguages. The symbols in theInternational Phonetic Alphabet that represent this sound are ⟨ʔ͡h⟩ and ⟨ʔ͜h⟩. The tie bar may be omitted, yielding ⟨ʔh⟩.

Features of a voiceless glottal 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 isglottal, which means it is articulated at and by thevocal cords (vocal folds).
• 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.
• Because the sound is not produced with airflow over the tongue, thecentral–lateral dichotomy does not apply.
• Itsairstream mechanism ispulmonic, which means it is articulated by pushing air only with theintercostal muscles andabdominal muscles, as in most sounds.
