Exam 3 Flashcards
relationship between tension (k) and fundamnetal frequency
K increase = F0 increase
K decrease = F0 decrease
Which muscles adduct the cartilaginous vocal folds?
Interarytenoid muscles (IA)
T/F when the vocal folds come together, air flow through the glottis is stopped
True
T/F All articulators can be moved by contracting muscles.
False
the velopharyngeal port closes for
gaging, vomiting, and swallowing
Every 1cm of H2O increase in P sub leads to a ? Hz increase in fo
2-4 Hz
What is a periodic source?
Repeating pattern, sound created from air being changed by vocal fold vibration
ratio of time the VFs are separated (allowing air to flow) compared to the period
Duty cycle
What is an aperiodic source?
No repeating pattern, sound created from air flowing between articulators
List the five layers of the vocal folds.
1.Epithelium
2-4. Lamina propria
Superficial lamina propria
Intermediate lamina propria
Deep lamina propria
5.Vocalis M.
Once the VFs are close enough together and the PTP is met, the VFs oscillate to _______________ and create a _____________
chop up the airflow and create a pressure wave
Movement of the VFs toward the midline
adduction
What are the places for consonant production (7)?
- Labial
- Labiodental
- Dental
- Alveolar
- Palatal
- Velar
- Glottal
True or False: Subglottal pressure is not required to set the vocal folds into vibration.
False, subglottal pressure IS required to set the VFs into vibration
Very soft sounds with low subglottal pressure and falsetto sounds happen when what tissue(s) are in vibration?
Only cover is in vibration
What type of disorder may result in problems with intensity variation in speech?
Parkinson’s disease
What happens if both the cover and body are in vibration?
contraction of the vocalis muscle in this case creates increased tension of the mucosa. This will increase the fundmental frequency
Fundamental frequency is a ? for pitch
physical term
What is an affricate?
Oral airway occluded; VP port closed -> air pressure builds up -> air pressure slowly released out the mouth
Adduction: some LCA and IA to bring the VFs to midline
Length of the VFs (long): high CT contraction and little VOC contraction
Is what vocal register?
Falsetto
True or False: Fundamental frequency rises at the end of declarative phrases and falls at the end of interrogative phrases.
False
What are the 3 mandibular planes:
- up and down, 2. side to side, 3. foward and backward
Movement of the VFs away from midline
Abduction
what you expect the sounds to feel like
somatosensory target
