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 .


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.
  • 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.
