The voiced velar tap is a rare type of consonantal sound, used in some spoken languages.
The International Phonetic Alphabet does not have a dedicated symbol for this sound, as it is deemed impossible on the IPA chart (where areas for impossible articulations are shaded gray), but the Kiel Convention of the IPA recommended that for taps and flaps where no independent symbol is provided, a homorganic consonant, such as a stop or trill, should be used with a breve diacritic:
"Tap or flaps: where no independent symbol for a tap is provided, the breve diacritic should be used, e.g. [ʀ̆] or [n̆]."[6]
So, following the conventions of the IPA, it can be represented by the voiced velar stop with a breve diacritic: [ɡ̆].
Features of the voiced velar tap:
Though deemed "impossible" on the IPA chart, a velar tap has been reported to occur allophonically in the Kamviri dialect of the Kamkata-vari language[1] and in Dàgáárè[2][3], though at least in the latter case this may in fact be a palatal tap. A recent study has also identified a voiced velar tapped fricative in Dàgáárè, which was previously unattested in human language.[4]
The rarity of the velar tap is explained by the physical limitations of the articulators: like a velar trill, a central velar flap or tap is difficult to produce because the tongue and soft palate cannot move together easily enough to produce the sound.[citation needed]
While a voiced velar central tap is considered extremely rare, a voiced velar lateral tap has been documented as an allophone in some languages of New Guinea, such as Kanite and Melpa. The extremely short duration of the [ʟ] in intervocalic position (20–30 ms) warrants calling it a tap, according to Ladefoged & Maddieson (1996).[5]
