The voiced uvular implosive is an extremely rare type of consonantal sound. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʛ⟩, a small capital letter G with a rightward pointing hook extending from the upper right of the letter.
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.
It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
The airstream mechanism is implosive (glottalic ingressive), which means it is produced by pulling air in by pumping the glottis downward. Since it is voiced, the glottis is not completely closed, but allows a pulmonic airstream to escape through it.
