WebMatch. Created by. pewterbaw TEACHER. Names and terminology for speech articulators. WebIn humans, vocalizations are modified in the airway above the vocal cords—the supralaryngeal vocal tract, or SVT—by positioning the tongue, lips, and larynx. This alters the overall shape of the SVT, allowing it to filter local energy peaks as they pass through it. As a result, the SVT acts on the acoustic signal in much the same way that a ...

WebThe supralaryngeal vocal tract, or SVT, determines the phonetic quality of speech sounds by serving as a filter for acoustic energy produced in the larynx. It does this by generating formant frequencies that differentiate vowels and consonants in much the same way as a pipe organ produces different notes.
