Description

AIRSTREAM MECHANISMS Pulmonic The air starts in the lungs

Pulmonic Egressive The air starts in the lungs and moves outwards Most commonly used mechanism (pulmonic consonants)

Pulmonic Ingressive The air starts in the lungs and moves inwards Not sure this is even possible?

Glottalic The air starts at the glottis

Glottalic Egressive The air starts at the glottis and moves outwards -

Air pressure builds up between vocal fold closure and another closure in the oral tract The larynx moves upwards Creating ejectives

e.g [k’] – marked by an apostrophe

Glottalic Ingressive The air starts at the glottis and moves inwards -

Pressure is built up and sucked inward There is closure in the vocal folds and the oral tract The larynx moves downwards suddenly and air is drawn into the vocal tract Creating implosives

e.g [ɓ] – marked with a right hook

Velaric The air starts at the velum, usually with the tongue (the main initiator)

Velaric Egressive The air starts at the velum and moves outwards Produces clicks e.g [ʘ]

Velaric Ingressive The air starts at the velum and moves inwards Produces ‘buccal speech’ – air compression at the velum combines with vibration of the tongue and cheeks...
