Research Abstract

This study aimed to develop a method for forensic speaker recognition, using global classification of speech. To confirm whether speakers were classified to a few classes, we conducted cluster analysis in which speakers were classified according to their formant frequencies. Formant frequencies were extracted from vowels of 319 female and 313 male speakers by ARX-based speech analysis method. In addition, a novel model for predicting formant frequency from speech signals was developed, which can efficiently represent speech information.
