Velocity used to calculate frequency for voice applications
Varies with medium
in air: speed of sound
for vocal folds: velocity in folds
Velocity of wave propagation through vocal folds
Identify trachea
Identify larynx
Identify pharynx
Identify nasal cavity
Identify mouth cavity
Identify soft palate
Identify epiglottis
Waveform produced by vocal folds in time
Triangular in shape
Spectrally rich (many higher order harmonics that are multiples of the fundamental frequency
How is pitch controlled by the vocal system?
Formula for frequency vs length of the vocal folds
Formants
resonant frequencies in the spectra of speech sounds
formed by resonance frequencies of various shapes of vocal tract
Shape of vocal tract is altered by movement of
pharynx, mouth, nasal cavity, tongue, lips, palate, soft palate, larynx, teeth, gums, glottis
