- Voiceless alveolar lateral fricative
The voiceless alveolar lateral fricative is a type of
consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabetthat represents voiceless dental, alveolar, and postalveolar fricatives is IPA|ɬ, and the equivalent X-SAMPAsymbol is K. The symbol IPA|ɬ is called "belted l" and should not be confused with "l with tilde", IPA| [ɫ] , which corresponds to 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. The sound is relatively rare among the world's languages. It is common among Native American languages, such as Navajo.

Features of the voiceless alveolar lateral fricative:
manner of articulationis fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.
place of articulationis alveolar, which means it is articulated with either the tip or the blade of the tongue against the alveolar ridge, termed respectively "apical" and "laminal".
phonationtype is voiceless, which means it is produced without vibrations of the vocal cords.
* It is an
oral consonant, which means air is allowed to escape through the mouth.
* It is a
lateral consonant, which means it is produced by allowing the airstream to flow over the sides of the tongue, rather than the middle of the tongue.
airstream mechanismis pulmonic egressive, which means it is articulated by pushing air out of the lungs and through the vocal tract, rather than from the glottisor the mouth.
Semitic languages, the sound still exists in contemporary SoqotriFact|date=July 2008. In Ge'ez, it is written with the letter ŚawtFact|date=July 2008.
