The voiceless alveolar lateral fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents voiceless dental, alveolar, and postalveolar lateral fricatives is [ɬ], and the equivalent X-SAMPA symbol is K.
The symbol [ɬ] is called "belted l" and is distinct from "l with tilde", [ɫ], which transcribes a different sound – the velarized (or pharynɡealized) alveolar lateral approximant, often called "dark L".[1]
Some scholars also posit the voiceless alveolar lateral approximant distinct from the fricative.[2] More recent research distinguishes between "turbulent" and "laminar" airflow in the vocal tract.[3] Ball & Rahilly (1999) state that "the airflow for voiced approximants remains laminar (smooth), and does not become turbulent".[4] The approximant may be represented in the IPA as ⟨l̥⟩.
In Sino-Tibetan language group, Ladefoged & Maddieson (1996) argue that Burmese and Standard Tibetan have voiceless lateral approximants [l̥] and Li Fang-Kuei & William Baxter contrast apophonically the voiceless alveolar lateral approximant from its voiced counterpart in the reconstruction of Old Chinese. Scholten (2000) includes the voiceless velarized alveolar lateral approximant [ɫ̥].
However, the voiceless dental & alveolar lateral approximant is constantly found as an allophone of its voiced counterpart in British English and Philadelphia English[5][6][7] after voiceless coronal and labial stops, who is velarized before back vowels, the allophone of [l] after voiceless dorsal and laryngeal stops is most realized as a voiceless velar lateral approximant.[8] See English phonology.
