Features
Features of the postalveolar ejective affricate: - Its manner of articulation is 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.
- Its place of articulation is palato-alveolar, that is, domed (partially palatalized) postalveolar, which means it is articulated with the front of the tongue behind the alveolar ridge, and the body of the tongue bunched up ("domed") at the palate.
- Its phonation type 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.
- The airstream mechanism is glottalic egressive, which means it is produced by pushing air with the glottis, rather than with the lungs.
In speech there are different ways of producing a consonant. ...
A sibilant, or a strident fricative, is a type of fricative, made by speeding up air through a narrow channel and directing it over the sharp edge of the teeth. ...
Affricate consonants begin like stops (most often an alveolar, such as or ), but release as a fricative such as or (or, a couple languages, into a fricative trill) rather than directly into the following vowel. ...

In speech, consonants may have different places of articulation, generally with full or partial stoppage of the airstream. ...
Palatalization means pronouncing a sound nearer to the hard palate, making it more like a palatal consonant; this is towards the front of the mouth for a velar or uvular consonant, but towards the back of the mouth for a front (e. ...
Postalveolar (or palato-alveolar) consonants are consonants articulated with the tip of the tongue between the alveolar ridge (the place of articulation for alveolar consonants) and the palate (the place of articulation for palatal consonants). ...

The alveolar ridge is the ridge on the roof of the mouth between the teeth and the hard palate. ...
