VERIFIED.
Anatomy section: covering what 3 systems? - ANS 1. Respiratory system: breath source
2. Laryngeal system: sound source
3. Supralaryngeal system: modulation source
The respiratory system (general info) - ANS Produces the air for speech production as well as
general breathing.
Inhalation and exhalation ratios - ANS Resting respirtion- 50:50
Speech production respiration: 10:90
When resting, the diaphragm is curved which direction? When it contracts it does what? -
ANS Upwards
Flattens
With inhalation, when the diaphragm contracts it does what to the ribs? - ANS Pushes them
down

Inhalation
The process of exhalation - ANS Lungs deflate
Diaphragm relaxes
Exhalation
The laryngeal system (general info) - ANS Production source
air from the lungs -> larynx -> vocal folds vibrate
What is the size of the vocal folds when resting open? - ANS 3/4 of an inch
In the Laryngeal system there is what? - ANS -The Hyoid Bone
