Proceedings of “Verificatori Biometrici” Workshop, organized by Technical University of Cluj-Napoca, Universitas Napocensis Babes-Bolyai, Universitas Medicinae et Farmaciae Napocensis and CNCSIS, Cluj-Napoca, Romania, May

Abstract

In this paper the GMM speaker model was analyzed from the viewpoint of its phonetic content. Phoneme distribution among clusters represented by Gaussians was studied. Special speaker models were also created using only a part of the training data, in order to identify the most valuable part of speech, for the purpose of speaker identification. Key words: Speaker Identification, Gaussian Mixture Models, Phonetic Analysis
