19 MFCCs with deltas and double-deltas were used as features. Two GMMs are built for real data and spoof attacks and the evaluation score is computed as a log-likelihood between these two GMMs.

Experiments which are referred by reports or by an associated attestation cannot be modified. You may revert the situation by deleting unpublished reports or the attestation in case they have not been published. Note you may still fork this experiment and re-run a modified or unmodified version of it.
