The alveolar ejective fricative is a type of consonantal sound, used in some spoken languages . The symbol in the International Phonetic Alphabet that represents this sound is ⟨sʼ ⟩ .
Features [ edit ] Features of the alveolar ejective fricative:
Its manner of articulation is sibilant fricative , which means it is generally produced by channeling air flow along a groove in the back of the tongue up to the place of articulation, at which point it is focused against the sharp edge of the nearly clenched teeth, causing high-frequency 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 laminal
Its phonation 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 only.
It is a central consonant , which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
The airstream mechanism is ejective (glottalic egressive), which means the air is forced out by pumping the glottis upward. Occurrence [ edit ] See also [ edit ] References [ edit ] External links [ edit ]
