Abstract

A correlogrcnn approach to the seîection of text-dependent feaîures m

vcweî souncis is invesiigaîed for speaker identificaîion. in the approach, vowel sounds

as the idenîity carrying parts in spoken utterances are represented m the form of a

correlogram, m whıch the speaker dependent spectral and temporaî information is

codsd. Psycho-physiologıcally motivated speclro-temporal correlation with a search

algoriihm is introduced to identify the regions vhere the relevanl features are

embedded thal are suited to discrimination. We identify Ihefeature regionsfor a set of

ındividuaî vowel sounds, and present resulîs on their effectiveness in identifying

speakers. Partıculccr to îhe approach is thaî U makes no explicit use of any individîial

speech features.
