Exam 3 COMD 282 Flashcards
Electromagnetic articulography
measures movement of tongue lips jaw and velum
stuttering articulation
longer voice onset times, larger jaw, lip and tongue movements
stuttering resonance
not significant
dysarthria CP and PD- articulation
errors including tone weakness and coordination
dysarthria CP and PD resonance
hypernasality
dysarthria ALS resonance
hyper nasality
dysarthria ALS articulation
imprecise articulation
cleft palate- articulation
fronting of velar production, sometimes posterior
velocardiofacial syndrome- resonance
hypernasality
velocardiofacial articulation
severe to normal
hearing impairment articulation
vowel neutralization, consonant errors
what is the source-filter theory
Source–> The basic source of power for speech is the respiratory system pushing air out of the lungs.
Filter–> The larynx, pharynx, nasal cavity, and oral cavity (= supralaryngeal vocal tract)
what is coarticulation
Movements related to sequentially occurring sounds overlap and interact.
Features of adjacent sounds (tongue advancement, etc) affect the production of their “neighbors”
what is the difference between apraxia and dysarthria
Apraxia: motor planning disorder which the brain can’t coordinate speech movements
dysarthria: motor speech disorder caused by weak muscles which affects phonation
articulatory characteristics of cleft palate
glottal stops _vf don’t get pushed together
nasal fricatives; talking through nose bc air way is abnormal
