V. Hubeika: Verifikace mluvčího s použitím JFA speaker faktorů jako vstupních parametrů do GMM a SVM klasifikatorů
FIT Božetěchova 2, seminární místnost UPGM L220 20.2.2009
Seminars are organized by Department of Computer Graphics and
Multimedia at the Faculty of Information Technology, Brno University of
Technology and Natural Language Processing Laboratory at the Faculty of
Informatics, Masaryk University, Brno. The seminars take place at VUT FIT Brno, Božetechova 2, L220, usually on Friday at 10:00.
In the standard approach of speaker verification, each speaker in the training set is represented by their own model.
IN the testing phase, given the test feature vector and the speaker model,
the task is to decide whether the features were generated by the model depending on the output score.
In this work,
only two models are trained.
Given two speech segments, encode them into one feature vector which is denoted as a
trial feature vector. It results in having two sets of trial features: target trial features and nontarget trial features.
Distribution of each set is then represented by one model. Given an input test trail feature vector, the task is to decide
whether it was generated by the target trial model or the nontarget trial model.
