respiratory mechanism
for speech production, pressure inside thoracic cavity will be greater than outside
external intercostals
raise ribs up and out to increase diameter of thoracic cavity
internal intercostals
pull ribs down to decrease size of thoracic cavity
pull lower ribs down and apart to decrease diameter of cavity
physiology of phonation
subglottic air pressure is higher than supraglottic. As the subglottic air pressure becomes too great to contain, the vocal folds are forced apart in a vibrating manner. the opening of the vocal folds begins posteriorly
Bernoulli effect
when a liquid or air moves through a constricted passage, the velocity increases and the pressure decreases.
process by which voiced breath stream is modified to enhance and dampen certain frequency components
pharyngeal cavity
part of upper airway; base of tongue is attached here
oral cavity
resonating structure for all sounds except /m,n,ng/
nasal cavity
many sounds can be produced with a nasal quality, but /m, n,ng/ are the only ture nasal sounds
the molding of the air stream into recognizable speech sounds by several structures in the mouth
made primarily by the obicularis oris muscle, play a particularly imp. role in production of bilabials /p,b,m/ and labiodental sounds /f,v/
lowers velum and elevates tongue
lowers velum and moves pharyngeal walls inward
velum/soft palate
begins at end of hard palate and extends back toward pharynx
acts as facilitator of articulation and resonance; forms floor of mouth and houses the lower teeth
directly involved in articulation of /f,v,th/
hard palate
bony structure separating oral cavity from nasal cavity; forms floor of nose and roof of mouth
alveolar ridge
place of lingual contact for several of the front sounds /t,d,s,z,n,l/
