An epiglottal or pharyngeal flap is not known to exist as a phoneme in any language. However, it exists as the intervocalic voiced allophone of the otherwise voiceless epiglottal stop /ʡ/ of Dahalo and perhaps of other languages. It may also exist in Iraqi Arabic, where the consonant 'ayn is too short to be an epiglottal stop, but has too much of a burst to be a fricative or approximant.
- Its manner of articulation is flap, which means it is produced with a single contraction of the muscles so that one articulator (usually the tongue) is thrown against another.
- Its place of articulation is epiglottal, which means it is articulated with the aryepiglottic folds against the epiglottis.
- Its phonation is voiced, which means the vocal cords vibrate during the articulation.
- 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.
