The voiced alveolo-palatal sibilant fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʑ⟩ ("z", plus the curl also found in its voiceless counterpart ⟨ɕ⟩), and the equivalent X-SAMPA symbol is z\. It is the sibilant equivalent of the voiced palatal fricative, and as such it can be transcribed in IPA with ⟨ʝ˖⟩.
Features
Features of the voiced alveolo-palatal fricative:
Its manner of articulation is sibilant fricative, which means it is generally produced by channeling air flow along a groove in the back of the tongue up to the place of articulation, at which point it is focused against the sharp edge of the nearly clenched teeth, causing high-frequency 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).
Somewhat obsolete in many words, in which most speakers realize it as hard [ʐː].[13] Present only in a few words, usually written ⟨жж⟩ or ⟨зж⟩. See Russian phonology
