Document Summary

Features of the source filter theory: fundamental frequency, de nition: slowest rate of vibration of the vocal folds. When there"s a peak it means the brain recognizes the difference. Slower, clearer marked by slight increase in intensity. Cochlea| viii nerve| cochlear nucleus| superior olivary complex| lateral leminiscus| inferior. The mel scale is a scale that measure frequency vs. pitch. It"s a perceptual scale, in which pitch is equidistant. The reference point is 1000 hz at 40dbl. The listener creates a scale of tones by doubling and halving the pitch of sounds. 1000 hz at 40 db sl is assigned a value of 1000 mels. A tone with twice the pitch will be 2000 mels and a tone with half the pitch will be 500 mels. Give an example of source- affected lter intact. Acoustic speech output= combination of a source of sound energy (the source) and modi ers that shape this output (the lter).
