Voice Quality Flashcards
1
Q
What are 4 items that describe normal voice quality?
A
- Maximum frequency range
- Minimum-maximum amplitude
- Maximum phonation time
- Minimal additive noise
2
Q
Maximum frequency range means
A
- The voice is flexible in pitch during conversation
3
Q
Minimum-maximum amplitude means
A
- The voice is able to vary loudness
4
Q
Maximum phonation time is measured by:
What is normal phonation time for adults and children?
A
- Measured by the longest period of time that an individual can sustain a vowel on one breath
- Adults: 15-25 seconds
- Children: at least 10 seconds
5
Q
What contributes to good phonation time?
A
- Coordinated air-flow with vocal fold adduction
6
Q
What is Dysphonia?
A
- Generic term for any voice that sounds deviant in terms of quality, pitch, and or loudness
7
Q
Dysphonia is measured in:
A
- Breathiness
- Rough/Hoarse voice
8
Q
Describe breathiness and how it is measured.
A
- Vocal folds don’t close completely during each vibratory cycle
- Air leakage at the glottis creates a friction noise
- Breathy noise is measured at the higher frequencies
9
Q
Describe a rough/hoarse voice and how it is measured.
A
- Excessive vocal fold closure during phonation
- Vocal folds vibrate in a less periodic cycle
- Rough/Hoarse noise is measured at the lower frequencies
10
Q
What is minimal additive noise?
A
- Minimal breathiness or roughness
