What is the difference between formant frequencies and pitch frequency?
Yes, F0 (the fundamental frequency) is the acoustic correlate of pitch (which is a perceptual concept). The fundamental frequency F0 is also the first harmonic H1 of the sound. If F0 is 100 Hz, the ...

What is the difference between formant frequencies and pitch frequency?
There is a limited sense in which F0 (which is the acoustic property perceived as pitch) and F1-F5 are not independent, which is that if you have a tiny larynx (high F0), given the nature of human ...
