Voiceless pharyngeal fricative

A voiceless pharyngeal fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is an h-bar, ⟨ħ⟩. In the transcription of Arabic, Berber (and other Afro-Asiatic languages) as well as a few other scripts, it is often written ⟨Ḥ⟩, ⟨ḥ⟩.

Typically characterized as fricative in the upper pharynx, similar to [h], except that the latter is placed at the glottis instead.
