Vowel
In linguistics, small perturbations in this quantity are known as jitter. The "velar pinch" refers to the fact that two forms of this quantity come near each other before a velar consonant, and is one example of the fact that values of this quantity for vowels undergo transitions based on the place of articulation of neighboring consonants. The auditory system is more sensitive to small changes in this quantity at the lower end of the audible range, which can be seen by plotting this quantity against a similar quantity which can be measured on the Bark scale or the mel scale. Vowel (*) formants are expressed in terms of values for this quantity. Aspects of the vocal tract can be modeled using band-pass filters, which attenuate components above and below cutoff values of this quantity. This quantity is typically plotted on the vertical axis of a spectrogram, with time on the x-axis. For 10 points, name this quantity, which is the physical analogue of pitch, and which is measured in hertz.
