    On the use of i-vector posterior distributions in Probabilistic Linear Discriminant Analysis

  • Original language description

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