vocal folds
source of sound
51
oral cavity
we change shape of it to shape the osunds
52
source-filter theory of sound production
- describes how oral cavity shapes speech - states that a voicing source is generated by vocal folds, routed through vocal tract, and then shaped into sounds of speech
53
articulators
