Exam 1 - CH 3 Flashcards
primary function for speech production
respiration
respiration
provides subglottic air pressure need to set vocal folds into vibration
production of voiced phonemes through vocal fold vibration in larynx
phonation
normal phonation
complete adduction of vocal folds
sufficient subglottic air pressure
Flaccid dysarthria, spastic dysarthria, neuromotor damage to laryngeal muscles
phonation
resonance
proper placement of oral or nasal tonality onto phonemes during speech by raising or lowering velum
produced when velum is raised and closes off nasal cavity from vocal air stream
oral resonance
produced when velum is lowered and oral cavity is blocked by lips or tongue
nasal resonance
damage to innervating velar muscles may cause
hypernasality to some degree
Neuromotor damage to nerves that innervate the vocal fold adductor muscles can have several effects on speech production
Flaccid dysarthria, spastic dysarthria, neuromotor damage to laryngeal muscles
Nerve damage > weak muscles to move air in/out of lungs > less air for speech production >
short phrases
reduced loudness
breathy voice
articulation
shaping of vocal air stream into phonemes that is accomplished by different structures within vocal tract
Neuromotor damage to articulators may affect
lips, tongue, jaw, velum, etc.
neuromotor damage affecting articulators results in
articulation errors
prosody
melody of speech using intonation and stress to convey meaning
