Ingressive sound

Sound made while inhaling by the nose or mouth Ingressive◌↓IPA number661EncodingUnicode (hex)U+2193 Image In phonetics, ingressive sounds are sounds by which the airstream flows inward through the mouth or nose. The three types of ingressive sounds are lingual ingressive or velaric ingressive (from the tongue and the velum), glottalic ingressive (from the glottis), and pulmonic ingressive (from the lungs). The opposite of an ingressive sound is an egressive sound, by which the air stream is created by pushing air out through the mouth or nose. The majority of sounds in most languages, such as /b/, are both pulmonic and egressive. Types Lingual Lingual ingressive, or velaric ingressive, describes an airstream mechanism in which a sound is produced by closing the vocal tract at two places of articulation in the mouth, then rarefying the air in the enclosed space by lowering the tongue, and then releasing either or both closures. These are the click consonants. Glottalic Glottal ingressive is the term generally applied to the implosive consonants, which when voiced actually use a mixed glottalic ingressive–pulmonic egressive airstream. Voiceless implosives are true glottalic ing
