Source filter model (4) - ACCURATE ANSWER~ the larynx serves as the sound source and its output is then sent into the vocal tract which filters it. ~ larynx on its on cant produce any sound unless there is pressure driving it ~ pressure comes from the lungs ~ vocal tract doesn't just filter but resonates or enhances some sounds Pitch (2) - ACCURATE ANSWERStretch the vocal folds to increase their tension and therefore increase the frequency at which they will vibrate ~ Contracting the cri...
