On the possibility of the skype channel speaker identification (on the basis of acoustic parameters)

Abstract

The paper presents the research method proposed for speaker identification by speech signals in the Skype system based on the use of speech pulse conversion (SPC). Speech signals recorded in an acoustic studio (anechoic chamber), and the same speech signals transmitted via the IP-telephony Skype channel were studied. The goal of the research was to identify individual features of the speaker’s vocal source (phonations) depending on the speech signal transmission channel in order to ascertain the possibility of speaker identification by speech characteristics in information systems.
