Abstract

Banks, amongst other businesses, will soon be under a great deal of pressure to improve the range and friendliness of their telephone-based services without compromising transaction security. Currently, automatic telephone services authenticate callers using a PIN-code and consequently do not offer a sufficient level of security for significant transactions; more sophisticated services, which depend on a human agent, demand lengthy authentication procedures. The technology of speaker verification has the potential to deliver fast and secure caller authentication for automated or agent-assisted telephone services. This paper gives an overview of the work of the CAVE consortium, a European-wide research project in speaker verification in which Ubilab is involved. Results obtained in experimental work so far compare favourably with the state of the art in speaker verification.
