    Formant Structure
    The resonance frequencies within the vocal tract are known as formants ($\text{F}1$, $\text{F}2$, $\text{F}3$, etc.). For vowels, the relative spacing between $\text{F}1$ and $\text{F}2$ reliably predicts the perceived tongue height and frontness. The absolute frequency of $\text{F}1$ is inversely proportional to tongue height, while $\text{F}2$ correlates positively with tongue frontness, provided the speaker maintains a constant palatal curvature index ($\text{PCI}$) (palatal curvature index (PCI)/)) $\text{[4]}$.
