Originální abstrakt

A PLDA model which exploits the uncertainty of the i-vectorextraction process has been presented. We derived the formulationof the likelihood for a Gaussian PLDA model based onthe i-vector posterior distribution, and illustrated a new PLDAmodel, where the inter-speaker variability is assumed to havean segment-dependent distribution, showing that we can rely on the standard PLDA framework simply replacing the likelihood definition.
