sibilantní

Sibilantní refers to sounds produced with a hissing quality, typically made by forcing air through a narrow channel between the tongue and the teeth or alveolar ridge. In phonetics, these are fricative consonants. The most common sibilant sounds in many languages are the voiceless alveolar fricative /s/ and the voiced alveolar fricative /z/. Other sibilant sounds can include the voiceless postalveolar fricative /ʃ/ (like the 'sh' in "ship") and its voiced counterpart /ʒ/ (like the 's' in "measure").

The production of sibilants involves creating turbulence as air passes through a constricted opening. This turbulence generates a distinct hissing sound. The precise location of this constriction and the shape of the tongue determine the specific sibilant produced. Sibilants are often prominent in speech due to their acoustic characteristics, which can make them susceptible to distortion or misarticulation, particularly for individuals with speech impediments or during rapid speech. The term "sibilant" originates from the Latin word "sibilare," meaning "to hiss." Many languages utilize sibilant sounds extensively in their phonological systems.
