Egressive sound

Speech sound made by exhaling air

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, glottalic egressive, and lingual (velaric) egressive. The opposite of an egressive sound is an ingressive sound, in which the airstream flows inward through the mouth or nose.
