A voiced velar lateral fricative is a rare consonantal sound that occurs as an intervocalic allophone of /𝼄/ in Nii and perhaps some related Wahgi languages of New Guinea.^{[citation needed]}

The symbol in the International Phonetic Alphabet that traditionally represents this sound is ⟨ʟ̝⟩, though in the extIPA, ⟨𝼄̬⟩ is preferred.

Features

Features of a voiced velar lateral fricative:

Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
Its place of articulation is velar, which means it is articulated with the back of the tongue (the dorsum) at the soft palate.
Its phonation is voiced, which means the vocal cords vibrate during the articulation.
It is an oral consonant, which means that air is not allowed to escape through the nose.
It is a lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.

Voiced post-palatal lateral fricative

A voiced post-palatal lateral fricative can be found in Archi, a Northeast Caucasian language of Dagestan, in which it is clearly a fricative, although further forward than velars in most languages, and might better be called prevelar.^[1]

Features

Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
Its place of articulation is post-palatal, also called retracted palatal, backed palatal, palato-velar, pre-velar, advanced velar or front(ed-)velar, which means it is articulated between the position of palatal consonants and velar consonants.
Its phonation is voiced, which means the vocal cords vibrate during the articulation.
It is an oral consonant, which means that air is not allowed to escape through the nose.
It is a lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.
