|
Term
| what is the source filter theory? |
|
Definition
energy from the vibrating vocal folds (the source) is modified by the resonance characteristics of the vocal tract (the filter)
- the vocal tract is visualized as a series of linked tubes |
|
|
Term
| what governs the resonance characteristics of the vocal tract? |
|
Definition
| changes in the configuration and shape of the articulators |
|
|

Term
| what are the three structures of the pharynx? |
|
Definition
| laryngopharynx, oropharynx and nasopharynx |
|
|
Term
| what two structures add resonance to sounds produced by the larynx? |
|
Definition
| laryngopharynx and oropharynx |
|
|
Term
| most pharyngeal muscles are innervated by which cranial nerves? |
|
Definition
|
|
Term
| what happens when the soft palate is lowered? raised/retracted? |
|
Definition
lowered: coupling of the nasal and oral cavities for nasal sounds or quiet breathing through the nose
raised/retracted: muscles of the pharynx move inward to meet the muscles of the soft palate, and the nasal port is then closed (thus, velopharyngeal closure) |
