Pitch tracking is a signal processing technique that estimates the fundamental frequency (F0) of an audio signal as a time-varying function, producing a pitch contour. The method operates by analyzing short time frames of the audio — typically using autocorrelation, cepstral analysis, or combined time-and-frequency approaches — to detect periodicity and extract the dominant pitch at each frame. The output is a sequence of frequency values over time, representing how pitch evolves across a speech or musical signal. Persistence occurs through algorithmic implementations in software, standardized test protocols, and established practice in music and speech processing.

Pitch tracking is designed and maintained for the sake of speech recognition — estimating F0 contours supports prosody analysis, speaker identification, and speech synthesis within SR systems. The servant points at the master: pitch-tracking exists to further speech-recognition's operation.
- cmsps9i0v06eejlssqrjcqyviINSTANCE_OF →
Pitch tracking is a specific kind of signal processing technique — a competent speaker would call it 'a signal processing method.' It answers exactly the INSTANCE_OF question: is X a specific case of the general Y?
- cmsr7end800hwkp539bqd8ok0DEPENDS_ON →
Pitch tracking's entire purpose is to estimate the fundamental frequency of a signal over time. The technique operates by detecting F0 — remove F0 as a concept and pitch tracking has nothing to track. DEPENDS_ON at the object level, not meta-level.
