Abstract

In this paper, a novel event detection pitch detector is presented Hilbert-Huang Transform is employed to locate the instant at which the glottal pulse takes place Then, the pitch period is detected accurately by measuring the time interval between two glottal pulses Experiments show encouraging detection results.
