Formant-tracking is a computational method that estimates the time-varying resonant frequencies of the vocal tract from speech signals by detecting spectral peaks in successive analysis frames. Parameters include frame size, window type, peak-picking threshold, and smoothing. It persists in speech processing literature, software libraries, and engineering practice.

Formant tracking as practiced today requires digital audio data as input. Remove digital audio and formant tracking stops operating — it has no data to analyze. The removal test passes.

Spectral analysis existed first and fed into formant tracking. Formant tracking builds on spectral decomposition techniques to track resonant frequencies over time, which came later.
- cmspqokmf0684jlss24yd0c6fDERIVED_FROM →
Formant-tracking derives from cepstral-analysis: the technique of identifying and tracking formant frequencies in speech builds on cepstral analysis methods that separate vocal tract resonance from excitation. Cepstral analysis is the general framework; formant-tracking is a specific application derived from it.
