A Robust and Alternative Approach to Zero Frequency Filtering Method for Epoch Extraction

Abstract

During production of voiced speech, there exists impulse-like excitations due to abrupt closure of vocal folds. These impulselike excitations are often referred as epochs or glottal closure instants (GCIs). The zero frequency filtering (ZFF) method exploits the properties of impulse-like excitation by passing a speech signal through the resonator whose pole… (More)
