What does FFT stand for? - fast Fourier transform What does a FFT spectrum show us? - shows us the range of harmonics that are present in sound, each peak shows a harmonic What will FFT not show us very well? - formants Is the FFT display useful for displaying features of the sound source or the...

a typical range of variation for fundamental frequency (F0) during reading passages would be about - 3 semitones the inverse square law means that - intensity decreases by a factor equal to the square of the change in distance Multiple vertical lines is a - harmonic series A single vertical lin...

harmonic spectral slope [how do steep or shallow slopes relate to voice quality?] - fundamental frequency harmonics are integer multiples result: a whole spectrum of sound F0 goes up, harmonics spread higher harmonics progressively weaker vital capacity - *the maximum amount of air that a pers...

If you were to produce a stop consonant, like a /t/ or a /d/, pressure would be higher or lower than a fricative? - higher than a fricative What will the oral air pressure be like when producing a vowel? - the same as atmospheric pressure around person's head. How do you calculate the average a...

vocal modulation - rhythmic changes that are predictable in fundamental frequency and in amplitude in the voice; gradual increases and decreases that occur over the course of many glottal cycles Sampling rate - the frequency with which numbers are stored or written down to represent the analog si...

How does sampling rate relate to playback quality, file size, frequencies saved in recording? - The higher the sampling rate, the bigger file size is needed and the higher quality you will have How does a complex periodic sound change when the fundamental is removed or muted? - when removed, the ...
