A speech signal can be decomposed into the fundamental frequency and harmonics, and the autocorrelation function (ACF) is an e!ective tool for identifying the fundamental frequency and the harmonics. This paper, thus, explains how ACF harmonic analysis can be applied to speech detection and reconstr
