Most of current speaker recognition systems are based on features extracted from the magnitude spectrum of speech. However the excitation signal produced by the glottis is expected to convey complementary relevant information about the speaker identity. This paper explores the use of two proposed glottal signatures, derived from the residual signal, for speaker identification. Experiments using these signatures are performed on both TIMIT and YOHO databases. Promising results are shown to outperform other approaches based on glottal features. Besides it is highlighted that the signatures can be used for text-independent speaker recognition and that only several seconds of voiced speech are sufficient for estimating them reliably.
