[edit] Features

alveolo-palatal fricative [ɕ, ʑ]

Features of the voiceless alveolo-palatal fricative:

Its manner of articulation is sibilant fricative: it is produced by directing air flow through a groove in the tongue at the place of articulation and directing it over the sharp edge of the teeth, causing high-frequency turbulence.
Its place of articulation is alveolo-palatal (palatalized laminal postalveolar): it is articulated with the front of the tongue behind the alveolar ridge, and the body (middle) of the tongue raised toward the palate.
Its phonation type is voiceless: it is produced without vibrations of the vocal cords.
It is an oral consonant: air is allowed to escape through the mouth.
It is a central consonant: it is produced by allowing the airstream to flow over the middle of the tongue, rather than the sides.
The airstream mechanism is pulmonic egressive: it is articulated by pushing air out of the lungs and through the vocal tract, rather than from the glottis or the mouth.
