Airstream Mechanisms: Glottalic Flashcards
Airflow: pulmonic egressive airflow mechanism
Pulmonic from the lungs
Initiated by diaphragm
Airflow can be
Ingressive or egressive
Air pressure terms
Supra-glottal air pressure
Sub-glottal air pressure
Increased air pressure
Decreased air pressure
Another word for increased air pressure is
Compression
Another word for decreased air pressure is
Rarefaction
What are the three airstream mechanisms?
Pulmonic
Velaric
Glottalic
In the Glottalic airstream mechanism what is the initiator?
The larynx
What is the initiator?
That which moves the air
Not articulation and not voicing(phonation)
Airstream from glottis
Closed glottis=no air from lungs
Air exists between glottis and lips-100cm3
Airstream from glottis is not
Air from the lungs,no air from under the glottis
The mechanism 1: How do we close the glottis?
Glottal stop
Coughing
The mechanism 2: how does this air (from glottis to lips) move?
Initiation of air-larynx moving up or down
Cv4 high pitch or low pitch
The larynx as initiator: larynx acts as piston
Larynx moved up-air out
Larynx moved down-air in
Larynx pushes
Air out or pulls air in
What are Glottalic sounds
Electives
Implosives
Voiced implosives
All non-English sounds
Articulation with Glottalic airstream:
Closure in oral cavity. Same places of articulation bilabial, alveolar,palatal and velar
Speech needs both
Closure at glottis and in oral cavity
Ejectives require
Closed glottis
Larynx as initiator
Larynx moves up
Egressive Glottalic airstream
Ejectives are
Egressive
With electives larynx needs to
Push air out
With ejectives air
Is rarefied- pressure drops
With ejectives
Not gap between ejectives and vowel
Sometimes in English ejectives are used
Non contrastively
Implosives require
Closed glottis
Larynx as initiator
Larynx moved down
Ingressive Glottalic airstream
Implosives are
Ingressive
With implosives the larynx needs to
Pull air in suction
With implosives
Air is compressed-pressure rises
Not common for implosives to be
Voiceless
Voiced implosives are the same as voiceless but
Glottis not completely closed
Voiced implosives require both
Glottalic airflow and pulmonic airflow
Implosives are
Ingressive
In implosives voicing requires
Pulmonic egressive
In voiced implosives air is
Sucked inwards and vocal folds vibrate
Voiced implosives can be
Bilabial Alveolar Velar Palatal Uvular
Ejectives and implosives in sprang disorder
Cochlear implant
Pig-bik
Other studies into cochlear implant found implosives for target plosives
What is the Glottalic airstream mechanism?
Air=supra-glottal (larynx to lips) with the larynx as initiator
Ingressive Glottalic mechanism
Larynx moved down
Used in implosives sounds
Egressive Glottalic mechanism
Larynx moved up
Used in ejectives sounds
