The voiceless alveolar tap or flap is rare as a phoneme. The symbols in the International Phonetic Alphabet that represent this sound are ⟨ɾ̥⟩ and ⟨ɾ̊⟩, combinations of the letter for the voiced alveolar tap/flap and a diacritic indicating voicelessness, either above or below the letter. The equivalent X-SAMPA symbol is 4_0.
Features of the voiceless alveolar flap:
A tapped fricative is in effect a very brief fricative, with the tongue making the gesture for a tapped stop but not making full contact. This can be indicated in the IPA with the lowering diacritic to show full occlusion did not occur.
Tapped fricatives are occasionally reported in the literature, though these claims are not generally independently confirmed and so remain dubious.
Flapped fricatives are theoretically possible but are not attested.
Features of the voiceless alveolar tapped fricative:
Reported from Turkish in a single source. A " voiceless apico-alveolar flap with variable friction" is reported as the word-initial allophone (and one of four word-final allophones) of /r/ in Kobon. It is also reported from Afenmai, where it is the "tense" equivalent of "lax" [ɾ].
