transcription: formula for %correct?

Answer 5

• # of words understood / # of total words

Question 6

transcription: diff ways to count # of words understood? (3)

Answer 6

• all words
• content words only
• grammatical correctness (if semantics is correct)

Question 7

basic rules of testing intelligibility? (5)

Answer 7

1. control what is being said (use unpredictable msg)
2. use phonetically balanced reading passages
3. use unfamiliar listeners
4. consider live vs recorded speech
5. consider quiet vs noise

Question 8

how does the frenchay test work? (4)

Answer 8

• shuffle cards
• pt reads aloud
• SLP transcribes
• SLP rates on 5-pt scale from “no abnormality” to “totally unintelligible”

Question 9

what are we measuring when considering speech effectiveness? (3)

Answer 9

1. speaking rate (WPM)
2. rate of intelligible speech (# of correctly transcribed words / duration of sample)
3. communication efficiency ratio (rate of intelligible speech / 190… <1.0 = compromised)

Question 10

at which level of the WHO-ICF does speech effectiveness measure disability?

Answer 10

activity level

Question 11

at which level of the WHO-ICF does speech comprehensibility measure disability?

Answer 11

activity level

Question 12

define speech comprehensibility

Answer 12

degree to which listener understands speech based on signal and ALL OTHER INFO (e.g., semantic context, gestures)

Question 13

FIB: semantic context (improvement of intelligibility up to _____% for severely impaired speakers).

gestures (____% improvement for both predictable and unpredictable sentences).

Answer 13

• 40
• 30

Question 14

T or F: intelligibility and comprehensibility are interchangeable terms

Answer 14

false – related but not the same

Question 15

perceptual speech ax tasks? (5)

Answer 15

1. sustained vowel
2. DDK
3. contextual speech (i.e., convo and narratives)
4. stress testing
5. ax motor programming capacity (e.g., subs and omissions)

Question 16

how to assess sustained vowel? (2)

Answer 16

• listen for voice quality, loudness, pitch, and steadiness
• take best out of 3

Question 17

MEDIAN and MINIMUM seconds for sustained vowel for young males and females vs elderly males and females?

Answer 17

• young males: 28.5 (min = 22)
• young females: 22.7 (min = 15)
• elderly males: 13.8 (min = 13)
• elderly females: 14.4 (min = 10)

Question 18

DDK: diff bw AMRs and SMRs?

Answer 18

• alternating motion rates (AMRs): ppp, ttt, kkk (tally how many in 3sec)
• sequential motion rates (SMRs): ptk ptk ptk (tally how many in 5sec)

Question 19

median DDK data for /p/ vs /t/ vs /k/ vs /p, t, k/ per second?

Answer 19

• /p/: 6.3 (min = 5)
• /t/: 6.2 (min = ~5)
• /k/: 5.8 (min = 4.4)
• /p, t, k/: 5 (min = 3.6)

Question 20

conversation and narratives are most useful tasks for evaluating the _________________.

Answer 20

integrated function of all aspects of speech

Question 21

examples of contextual speech? (3)

Answer 21

• open-ended questions
• pic description
• reading standard passage

Question 22

how to do stress testing (2)? what are you looking for (3)?

Answer 22

• how: 1) instruct pt to read aloud or count for 2-4mins. 2) ax strength before and after task.
• looking for: 1) deterioration in voice quality, 2) resonance, or 3) artic.

Question 23

which motor speech disorder may you suspect if the pt’s voice deteriorates during stress testing but then improves after a few mins of rest?

Answer 23

myasthenia gravis

Question 24

what do contrastive stress activities give insight to?

Answer 24

prosody

Question 25

provide the name for the described published dysarthria tests: a) ax across subsystems, provides severity ratings, and is useful for determining dysarthria subtype. b) captures impairment-level features + functional impact while also determining subtype. c) 5-pt rating scale + also observes OME and speech.

Answer 25

a) dysarthria examination battery (DEB) b) newcastle dysarthria ax (NDAT) c) frenchay dysarthria ax-2 (FDA-2)

Question 26

which ax measure for functional communication + psychosocial impact has unidimensionality, local independence, good measurement precision, and differential item analysis

Answer 26

communicative participation item bank (CPIB)

Question 27

PROM are relevant to movement toward... (3)

Answer 27

1. value-based care 2. client-centred care 3. perceived value by clients and families

Question 28

in what year did perceptual studies of dysarthria begin, leading to the mayo clinic system?

Answer 28

1960s-70s (pre 60s = homogenous view of dysarthria)

Question 29

mayo clinic system (4)

Answer 29

- dysarthria is recognized by sound - distinguishable from normal speech and non-neurologic speech disorders - differences go beyond severity variations - similarities reflect lesion loci + underlying pathophysiology

Question 30

conclusions from original DAB studies? (2)

Answer 30

- each group has unique patterns - dysarthria types can be distinguished aud-perceptually

Question 31

DAB dysarthria clusters (???)

Answer 31

slide 38

Question 32

diagnostic loop of dysarthria today? (4)

Answer 32

1. listen 2. localize 3. explain 4. plan tx
