Voiced alveolo-palatal fricative

Features of a voiced alveolo-palatal fricative:

• Its manner of articulation is sibilant (a subclass of fricatives and affricates), which means it is generally produced with a higher-frequency turbulence. Sibilants may be articulated with various tongue shapes and degrees of palatalization, depending on their place of articulation.
• Its place of articulation is alveolo-palatal. This means that:
  • The articulation is postalveolar and laminal, meaning that the tongue blade contacts the roof of the mouth in the area behind the alveolar ridge (the gum line). Some phoneticians instead argue that the articulation is pre-palatal and dorsal, meaning that the back of the tongue (the dorsum) is raised toward the front of the hard palate.
  • It is heavily palatalized, meaning that the middle of the tongue is bowed and raised towards the hard palate.
• Its phonation is voiced, which means the vocal cords vibrate during the articulation.
• It is an oral consonant, which means that air is not allowed to escape through the nose.
• It is a median consonant, which means it is produced by directing the airstream down the midline of the tongue, rather than to the sides.
• Its airstream mechanism is pulmonic, which means it is articulated by pushing air only with the intercostal muscles and abdominal muscles, as in most sounds.
