In articulatory phonetics , consonants produced by lowering the soft palate are called nasal consonants. There are also nasal vowels. The nasal consonants are almost always occlusive , but it also exists in some languages such as Gaelic and fricative nasal (however obtained by two joints are linked by a phase disocclusion to produce the fricative).

They are occlusive because although the pulmonary flow flows through the nasal cavity, it is stopped in the mouth.

The occlusive nasal part of the family of continuous , that is to say they do not block the expired air (as opposed to occlusive or fricative oral ) and are almost always voiced.

From a sound standpoint, the nasal plosives have a sound spectrum between 200 and 2000 Hz.

The French has the nasal following:

  • (although the symbol is rather reserved for the nasalization of vowels ).

    Nasal discharge is sometimes noted in the API symbol superscript (used for prnasalisation consonants), although this notation is imprecise.

    Where symbols appear in a box, the left represents a voiceless consonant , the right one voiced consonant (not applicable to clicks). Boxes separated by dotted lines normally use the same symbols API base and differ only by diacritical possibly applied to move their joints. Fields marked with an asterisk (*) indicate sounds not yet represented formally documented in the API. Shaded areas indicate a link that seemed impossible. The empty white boxes indicate theoretical articulations possible but not yet certified. The affricates ts, dz, t, d, t, d are rated using ligatures , , , , , common use, no longer part of the API (it is recommended replace them with two joints, associated with a ligature pull -subscribed-or superscript or with the fricative superscript). The occlusive injective deaf in italics, sometimes used, are no longer part of the API (it is recommended to replace the symbol of the voiced consonant devoicing of the diacritic).
