Features

Features of the alveolo-palatal ejective fricative:

Its manner of articulation is fricative, which means it is produced by constricting air flow through a narrow channel at the place of articulation, causing turbulence.

Its place of articulation is alveolo-palatal. This means that:

Its place of articulation is postalveolar, meaning that the tongue contacts the roof of the mouth in the area behind the alveolar ridge (the gum line).

Its tongue shape is laminal, meaning that it is the tongue blade that contacts the roof of the mouth.

It is heavily palatalized, meaning that the middle of the tongue is bowed and raised towards the hard palate.

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.
