Document Summary
Cmd 276 - lecture 5 - voice fundamental frequency. Rate of vocal fold vibration is determined by their mass, tension, and length. Greater mass, less tension and stiffness slower rate of vibration, lower f0. F0 is more affected by tension of the vocal fold cover than length of the folds. Increase in medial compression vocal folds more tightly compressed for a longer amount of time. Get more subglottal pressure stronger force blowing folds apart and stronger excitation of air molecules of the vocal tract. Folds then come together more forcefully as well. The human voice can be depicted on a line spectrum glottal spectrum. Depicts the voice at the level of the larynx, before it"s modified in the vocal tract. F0 is the lowest frequency with the highest amplitude. Roll off rate - how much the amplitude decreases when frequency increases.
