In this paper, we present a new longitudinal and bilingual broadcast database designed for speaker clustering and textindependent verification research. The broadcast data is extracted from the archives of Omrop Fryslân which is the regional broadcaster in the province of Fryslân, located in the north of the Netherlands. Two speaker verification tasks are provided in a standard enrollment-test ...

The description and characterization of the Italian speech database SIVA is given. After a brief review of the available corpora designed for speaker verification task, we introduce the “Speaker Identification and Verification Archives: SIVA”, a database that consists actually of more than two thousands calls, collected over the public switched telephone network. A detailed description of speec...

This paper proposes features based on parametric representation of Fourier phase of speech for speaker verification. Direct computation of Fourier phase suffers from phase wrapping and hence we attempt parametric modelling of phase spectrum using an allpass (AP) filter. The coefficients of the AP filter are estimated by minimizing an entropy based objective function motivated from speech produc...

In this contribution a novel system of speaker segmentation has been designed for improving safety on voice communication in air traffic control. In addition to the usage of the aircraft identification tag to assign speaker turns on the shared communication channel to aircrafts, speaker verification is investigated as an add-on attribute to improve security level effectively for the air traffic...

This paper demonstrates the performance gap between speaker verification over land-line telephone networks and speaker verification over cellular networks. The paper shows that the cellular coding accounts for only a fraction of the observed performance gap. A dual-channel corpus, with speakers recorded simultaneously in a land-line phone and a cellular phone, is used to study the effect of the...
