The voiced dental click is a click consonant found primarily among the languages of southern Africa. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ǀ̬⟩ or ⟨ᶢǀ⟩; a symbol abandoned by the IPA but still preferred by some linguists is ⟨ʇ̬⟩ or ⟨ᶢʇ⟩.
In languages which use the Bantu letters for clicks, this is most commonly written ⟨gc⟩, but it is written ⟨dc⟩ in those languages that use ⟨g⟩ for the uvular fricative.
Features of the voiced dental click:
The airstream mechanism is lingual ingressive (also known as velaric ingressive), which means a pocket of air trapped between two closures is rarefied by a "sucking" action of the tongue, rather than being moved by the glottis or the lungs/diaphragm. The release of the forward closure produces the "click" sound. Voiced and nasal clicks have a simultaneous pulmonic egressive airstream.
