A voiced uvular tap or flap is a type of consonantal sound, used in some spokenlanguages.
There is no dedicated symbol for this sound in the IPA. It can specified by adding the extra-short diacritic to the letter for the uvular plosive, ⟨ɢ̆⟩, but it is also often covered by the unmodified letter for the uvular trill, ⟨ʀ⟩, since the two have never been reported to contrast and a uvular tap or flap is not known to exist as a phoneme in any language.
In some languages a uvular tap is reported is said to vary allophonically with a uvular trill, and is most likely a single-contact trill [ʀ̆] rather than an actual tap or flap [ɢ̆] in these languages.
