Q

4 basic processes for speech production

A

respiration - power for speech
phonation - produce voice
articulation - form speech sounds
resonance - alters sounds

Q

how does aging affect the thorax

A

rib cage more concave, ribs get closer, thorax stiffer, costal cartilages ossify leading to decreased chest wall compliance

Q

what happens to lower airways as we age

A

bronchi and lungs descend in thorax, pleural becomes less elastic with more collagen reducing elasticity

Q

how does speech breathing change in older adults

A

larger lung and rib cage volumes
fewer syllables per breath
greater lung volume per syllable

Q

what are the changes in the craniofacial skeleton due to aging

A

alters points of muscle attachment, affecting speech efficiency, loss of alveolar bone from tooth loss changing the oral cavity shape

Q

how does aging affect respiration for speech

A

weakness and lack of control of exhalation may lead to prosodic changes, fatigue, and more frequent pauses

Q

how does aging affect phonation

A

hoarse, breathy speech, overall muscle weakness and pitch changes

17
Q

how does aging affect resonance

A

increase in oral cavity size and lowering of larynx might change formants

18
Q

how does aging affect articulation

A

muscle atrophy leads to reduced extent and speed of movement of articulatiors

19
Q

what areas of the brain are important for speech and swallowing

A

brainstem
frontal lobe
parietal lobe
occipital love
temporal lobe

20
Q

what happens in brocas area

A

motor speech production
damage can result in aphasia

21
Q

what happens in wernickes area

A

auditory comprehension
damage can lead to fluent but nonsensical speech

22
Q

frontal lobe

A

executive function

23
Q

parietal lobe

A

tactile/kinesthetic sensations

24
Q

temporal lobe

25
Q

occipital lobe
