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 letter ⟨ɬ⟩ is called "belted l" and should not be confused with "l with tilde", ⟨ɫ⟩, which transcribes a different sound, the velarized alveolar lateral approximant. It should also be distinguished from a voiceless alveolar lateral approximant, although the fricative is sometimes incorrectly described as a "voiceless l", a description fitting only of the approximant.
