Articulation & Resonance Flashcards
1
Q
What is the Source-Filter Theory of Vowel Production?
A
- Speech is the product of sending an acoustic source, such as the sound produced by the vibrating vocal cords, through the filter of the vocal tract that shapes the output.
2
Q
Speech is the product of _____________________, such as the sound produced by the vibrating vocal cords, through the __________________ that ____________________________.
A
- sending an acoustic source
- filter of the vocal tract
- shapes the output
3
Q
What is resonance?
A
- The sound quality given to voice sounds by the vocal tract
4
Q
What can change the resonant frequencies of the vocal tract?
A
- Length of the vocal tract
- Location of the constriction
- Degree of constriction
5
Q
What can cause resonance problems?
A
- Problems with the velopharyngeal closure
6
Q
How is velopharyngeal closure accomplished?
A
- By elevation and retraction of the velum
- And contraction of the superior pharyngeal constrictor
7
Q
List 4 Resonance problems.
A
- Hypernasality
- Hyponasality
- Nasal emissions
- Cul-de-sac resonance
8
Q
Describe hypernasality
A
- Excessive nasal resonance
9
Q
Describe hyponasality.
A
- Insufficient nasal resonance
10
Q
Describe nasal emissions.
A
- Air escapes through nasal cavities
11
Q
Describe cul-de-sac resonance.
A
- Muffled sound to the voice
(It reminds me of the sound of an instrument with a mute in it.)
