Voiced alveolo-palatal fricative
The
voiced alveolo-palatal voiceless or
laminal postalveolar fricative is a type of
consonantal sound, used in some
spoken languages. The symbol in the
International Phonetic Alphabet that represents this sound is , and the equivalent
X-SAMPA symbol is
z\.
Features of the voiced alveolo-palatal fricative:
* Its
manner of articulation is
sibilant fricative, which means 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, that is,
palatalized laminal postalveolar, which means it is articulated with the blade of the
tongue behind the
alveolar ridge, and the body of the tongue raised toward the
palate.
* Its
phonation type is voiced, which means the vocal cords are vibrating during the articulation.
* 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 middle of the tongue, rather than the sides.
* The
airstream mechanism is
pulmonic egressive, which means it is articulated by pushing air out of the
lungs and through the vocal tract, rather than from the
glottis or the mouth.
It is found in such Polish words as
bazia 'catkin'.
In Russian, the voiced alveolo-palatal fricative is only found
geminate:
*жжёшь 'you (sg) burn'
