The original text was copied without attribution (including appropriate references to the original author(s) and/or paper title) and without permission."Improved SVM Speaker Verification Through Data-Driven Background Dataset Selection"by Mitchell McLaren, Brendan Baker, Robbie Vogt, Sridha SridharanIEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP), 2009, pp. 4041-4044In this paper, we propose an automatic data-driven technique for selecting proper background dataset. By the technique, impostor confidence(IC) is proposed as a metric and more discriminative background dataset is automatically chose by impostor confidence(IC) to train more discriminative model. Experiment results on NIST 2008 SRE corpus in GMM-SVM speaker verification system show that the proposed approach obtains better performance. Relative decline in mincost of 8.9% in female and 4.6% in male is obtained. with female and male combined, 5.4% relative decline in mincost is obtained over Heuristically selected background dataset.
