ASVspoof 2019 participants may wish to read our Odyssey 2018 paper which describes the t-DCF metric. It will be the default metric for ASVspoof 2019.

T. Kinnunen, K.-A. Lee, H. Delgado, N. Evans, M. Todisco, M. Sahidullah, J. Yamagishi, D.-A. Reynolds, "t-DCF: a Detection Cost Function for the Tandem Assessment of Spoofing Countermeasures and Automatic Speaker Verification", Proc. Odyssey 2018 - The Speaker and Language Recognition Workshop [PDF]

Software implementations of the t-DCF metric can be downloaded in MATLAB and Python formats.
