Abstract
Frequency variations according to time can be estimated by tracking specific features along time. Solutions are proposed to follow the time variation of the dominant frequency, the fundamental frequency, and speech formants. The Hilbert analytic signal and the zero-crossing method are shown to estimate the instantaneous frequency, and the Teager-Kaiser energy operator is described to track energy variations.
