"Phoneme"Airstream Mechanism:
airstreamType:
stringDescription
The airstream mechanism used to pronounce this Phoneme.
Pulmonic(egressive) sounds are created by pushing air out of the lungs.Ejectivesounds are glottalic egressive sounds where the air column is compressed by upward movement of the glottis.Implosivesounds are glottalic ingressives where air is pulled in by a downward movement of the glottis.Clicksounds, i.e. lingual / velaric ingressive sounds, pull air in with a downward movement of the tongue.Allowed Values
"click""ejective""implosive""ingressive""pulmonic"

Backness:

stringDescription

Allowed Values
"front""near-front""central""near-back""back"
Features:
featuresType:
arrayDescription
A list of the phonemically distinctive features of this Phoneme. These are what are listed under
diacriticsin the IPA chart. For example, if a language distinguishes between a palatalized/t/and a plain/t/, the first should include the featurepalatalizedand the secondplain(or no features). Note that most features are also a manner of articulation as well, so it up to the linguist to decide when a given phonetic detail is a manner, or when it is a feature (i.e. a diacritic). For example, a language might distinguish phonemically between a palatal plosive/c/and a palatalized plosive/tʲ/. The first would listpalatalas its place of articulation, while the second would listpalatalizedas a distinctive feature. Do not include features here if they are already used for manner, unless your analysis is that this feature is both a manner and a feature of this phoneme, e.g. a palatalized palatal stop. This field is used primarily for consonants, but may also apply to vowels as well (e.g. thecloseandopenfeatures).Items must be unique:
