What is the perceptual correlate of fundamental frequency (F0)?

Explanation:
F0 is the rate at which the vocal folds vibrate, producing a periodic waveform. The perceptual attribute that this rate maps to is pitch—the listener’s sense of how high or low a sound is. When F0 increases, pitch sounds higher; when F0 decreases, pitch sounds lower. Jitter reflects small irregularities in the vibration rate rather than the perceived pitch, HNR measures how much of the signal is noise versus harmonic content, and loudness relates to acoustic power, not the frequency-based sense of pitch. So the perceptual correlate of F0 is pitch.
