|Issue Date:||2001||Publisher:||1070-9908||Journal:||IEEE Signal Processing Letters||Abstract:||This paper presents a new method for detecting the instants of glottal closure (IGC), or epochs, in noisy environments based on the Cohen's class time-frequency representations (TFR), We define a detection function inspired in a time-frequency formulation for optimum detection and apply a morphologic closing over it to determine the epochs. It compares favorably with other methods (e.g., the SIFT-based and the Frobenius Norm [FN] function) in different levels of Gaussian noise. Experiments are carried over a data base compossed of ten speakers.||URI:||http://hdl.handle.net/10553/52460||ISSN:||1070-9908||DOI:||10.1109/97.935737||Source:||IEEE Signal Processing Letters[ISSN 1070-9908],v. 8, p. 225-227|
