Recent Advances in Automatic Speaker Verification
LOCATION: Auditorium 1, TEL, Ernst-Reuter-Platz 7, 20th floor

SPEAKER: Michael Wagner (TU Berlin)
The human voice uniquely combines physical and behavioural traits of the individual. Large intra-person variance, channel and environmental variation present challenges for speaker verification, while the universality of speech and the ubiquity of the telephone make the voice a very useful biometric for authentication and forensic applications. The field has seem enormous progress in recent years with equal-error rates for clean signal having dropped to below 1% in state-of-the-art systems. Recent advances based on the UBM-GMM framework, including factor analysis, iVectors and PLDA as well as calibration and specific forensic speaker comparison issues, are presented in this talk.
