Glottal activity detection using Finite Rate of Innovation methods

A novel algorithm which accurately determines the glottal closing instants and glottal opening instants from the Differentiated Electroglottographic signals is presented.The glottal closing instants and glottal opening instant are modeled as non-bandlimited signals and methods for sampling and reconstructing signals with Finite Rate of Innovation are then used to recover the glottal closing instants and glottal opening instants. In comparison with existing methods, the proposed scheme achieves improved performance by providing 99% reliable estimates of glottal closing and opening instants respectively.
