In human speech, egressive sounds are sounds in which the air stream is created by pushing air out through the mouth or nose. The three types of egressive sounds are pulmonic egressive (from the lungs), glottalic egressive (from the

Pulmonic egressive

Pulmonic In phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation and articulation, it is one of three main components of speech production. The airstream mechanism is mandatory for sound ...

ejective In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with aspirated, voiced and tenuis consonants. So ...

Lingual egressive

The lingual egressive, also known as velaric egressive, involves a double closure similar to that of the lingual ingressive sounds known as clicks, but with airflow in the opposite direction. With the velum closed, the speaker forces air out of the mouth using either the tongue or cheeks, as in the French expression of dismissal.
