- Postalveolar ejective affricate
The postalveolar ejective affricate is a type of
consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabetthat represents this sound is IPA|tʃʼ.
Features of the postalveolar ejective affricate:
manner of articulationis sibilant affricate, which means it is produced by first stopping the airflow entirely, then directing it through a groove in the tongue and over the sharp edge of the teeth, causing high-frequency turbulence.
place of articulationis "palato-alveolar", that is, domed (partially palatalized) postalveolar, which means it is articulated with the front of the tonguebehind the alveolar ridge, and the body of the tongue bunched up ("domed") at the palate.
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
central consonant, which means it is produced by allowing the airstream to flow over the center of the tongue, rather than the sides.
airstream mechanismis glottalic egressive, which means it is produced by pushing air with the glottis, rather than with the diaphragm.
