Term
Thalmus
Definition
behind the basal ganglia
a collection of subcortical neurons
receives info that is relayed between areas of the brain
Term
basal ganglia
Definition
the front half of the brain is a collection of subcortical bodies called basal ganglia

the bodies are highly connected to the cerebellum and to the cortical regoins involved in the movement
Term
hemispheres
Definition
both cerebrum and cerebellum are dived into 2 hemispheres

hemisphers of the cerbrum join at the midline by the corpus callosun
Term
cerebellum
Definition
sits below the cerebrum and behind the brain stem
Term
cerebrum
Definition
occupies the majority of the brain activity in the head
Term
hard palate
Definition
extends from the alveolar ridge and tooth sockets of the maxillary dentition

arched structure with a vaulted ceiling that contributes to oral resonance
Term
lips
Definition
made up pf facial muscles which make it possible for them to move
Term
cortex
Definition
contains layers of neurons
also called "gray matter"
Term
occipital lobes
Definition
at the back of the brain receives and processes visual information
Term
temporal lobes
Definition
contain the primary auditory cortex as well as regions important for language comprhasion memory
Term
parietal lobes
Definition
contain the sensory cortex which receives sensory information from the body as well as othe regions that support the cognitive functions
Term
frontal lobes
Definition
contain the primary motor cortex that send neural commands to specific parts of the body
Term
denasality
Definition
insufficient nasal resonance often related to excessive velopharyngeal closure
Term
velum
Definition
a musclar structure
noticeable for the uvula
Term
hypernasality
Definition
failure to move the velum rapidly enough to match the demands of the particular untterance resulting in excessiveley nasal speech
Term
mandiable
Definition
lower jaw, moves alot during speech
Term
pharynx
Definition
the first are of the vocal tract through which the sound waves travel immidiately above the larynx

height of the pharynx changes as the laryns rises
Term
subglottal air pressure
Definition
caused by the outgoing air building up below the vocal folds
Term
glottis
Definition
the area between the vocal fold
Term
Tongue
Definition
how our tongure is postured influences the overall resonance and sound of the voice and is critical for the production of individual speech sounds
Term
respiration
Definition
power supply
Term
phonation
Definition
vibrations to make sound
Term
resonance
Definition
acts as a filter. inside the mouth
Term
LArynx
Definition
the sound producing organ for speech (voice box)
Term
intensity
Definition
measure of sound pressure

Term
affricative
Definition
combination of stop and fricative
Term
stop (plosive)
Definition
sudden release of air
Term
nasal
Definition
made with velophranyngeal port open
Term

consonant vowel utterings, non specific
Term
coarticulation
Definition
production of a phone simultaneous with production of adjacent phone.

ommision
Definition
when a speaker omits sounds from words
Term
