The fundamental frequency or F0 is the frequency at which vocal chords vibrate in voiced sounds. This frequency can be identified in the sound produced, which presents quasi-periodicity, the pitch period being the fundamental period of the signal (the inverse of the fundamental frequency). Pitch is more often used to refer to how the fundamental frequency is perceived.
