Fast Scoring for PLDA with Uncertainty Propagation

  author={Wei-Wei Lin and Man-Wai Mak},
By treating utterances as points in the i-vector space, ivector/PLDA can achieve fast verification. However, this approach lacks the ability to cope with utterance-length variability. A method called uncertainty propagation (UP) that takes the uncertainty of i-vectors into account has been recently proposed to deal with this problem. However, the loading… CONTINUE READING
