Tippett plots showing the actual LR distributions. Tippett plots showing the actual LR distributions when H so (blue lines) and H do (red lines) are respectively true for different systems evaluated on the 60 female speaker database under studio-clean (top row), degraded mobile to landline (second row from top) and mismatched (third row from top) conditions and 90 male speaker database under studio-clean (bottom row) conditions. The solid lines represent the C llr values, and dashed lines to the left and right of the solid lines show the estimates of the 95% CI values. GMM-UBM: (a-d). SVM: (e-h). Gradient projection, s ℓ1norm: (i-l). LS, s ℓ1norm: (m-p).
