Q

What are the 5 steps you would take for a clinical evaluation of a a voice

A
  1. Interviewing
  2. Observing
  3. Describing the voice
  4. Comparing observations to standards and normal
    values
  5. Integrating information to determine treatment

14
Q

What causes a decrease in the z part of s:z ratio

A

Disturbances in glottic function are reflected by a decrease in the duration of z (as a consequence of inadequate vocal cord closure and subsequent air escape)

16
Q

What is a Auditory-perceptual voice profiles

A

System to assess clients vocal qualities, i.e GRBAS or CAPE-V

17
Q

What does intensity (dB) measure

A

Volume, noise level

18
Q

What is fundamental frequency

A

the frequency at which vocal folds vibrate,

19
Q

What is shimmer

A

Assessment of amplitude variability, higher shimmer indicates possible voice disorder, can be used to evaluate voice quality and monitor changes over time

20
Q

What is jitter

A

Measures variation of fundamental frequency, higher jitter indicates greater pitch variability associated with voice disorders.

21
Q

Normal shimmer %

A

3-4%

22
Q

Normal jitter %

A

1-2%

23
Q

What is pitch measured in

A

Measured by fundamental frequency

24
Q

What does dB measure

A

Loudness

25
Q

What is pertubation referring to

A

Quality

26
Q

What is resonancence

A

nasality , how palate, noise or mouth impacts resonance

27
Q

What is Hz

A

number of vocal fold vibrations per second

28
Q

Avg Hz for m and f

A

200Hz - women, 120Hz - men

29
Q

What is the harmonic to noise ratio

A

Measures the harmonic component vs the non harmonic component in the acoustic signal of the human voice

30
Q

What does a higher or a lower HNR value indicate

A

Higher indicates a more harmonic rich voice vs lower indicates more noise or a less periodic signal

31
Q

Appropriate measure for mild to moderate dysphonia

A

Harmonic to noise ratio

32
Q

Appropriate measure for severe dysphonia

A

Cepstral peak performance (CPP)

33
Q

What is normal CPPS of connected speech

A

4 or higher

34
Q

Why is CPP better for severe dysphonia compared to HNR

A

Because HNR has to be used on a sustained vowel, cant be used on a sentence

35
Q

Normal HNR or a /a/ or /i/

A

20, below considered noticeable hoarsness

36
Q

What is Electroglottography

A

Non-invasive analyses of vocal folds, measures the contact area and closeness of vocal folds as they vibrate

37
Q

two examples of auditory perception of voice scales

A

GRBAS and CAPE-V

A
