The voiced alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiced dental, alveolar, and postalveolar lateral fricatives is ⟨ɮ⟩ (sometimes referred to as lezh), and the equivalent X-SAMPA symbol is K\.
Features
Features of the voiced alveolar 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 alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal.
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 lateral consonant, which means it is produced by directing the airstream over the sides of the tongue, rather than down the middle.
The voiced alveolar non-sibilant fricative (also known as a "lisp" fricative) is a consonantal sound. Consonants is pronounced with simultaneous lateral and central airflow.
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. However, it does not have the grooved tongue and directed airflow, or the high frequencies, of a sibilant.

U+1DF05𝼅LATIN SMALL LETTER LEZH WITH RETROFLEX HOOK is an extension to IPA for disordered speech (extIPA)[9][10]
Notation
Former IPA symbol for the voiced alveolar lateral fricative
In 1938, a symbol shaped similarly to heng ⟨ꜧ⟩ was approved as the official IPA symbol for the voiced alveolar lateral fricative, replacing ⟨ɮ⟩. It was suggested at the same time, however, that a compromise shaped like something between the two may also be used at the author's discretion. It was this compromise version that was included in the 1949 Principles of the International Phonetic Association and the subsequent IPA charts, until it was replaced again by ⟨ɮ⟩ at the 1989 Kiel Convention.[11] Despite the Association's prescription, ⟨ɮ⟩ is nonetheless seen in literature from the 1960s to the 1980s.[12][13][14][15][16]
