A speaker verification backend with robust performance across conditions
In this paper, we address the problem of speaker verification in conditions unseen or
unknown during development. A standard method for speaker verification consists of …

Toward fail-safe speaker recognition: Trial-based calibration with a reject option
The output scores of most of the speaker recognition systems are not directly interpretable
as stand-alone values. For this reason, a calibration step is usually performed on the scores …

A discriminative condition-aware backend for speaker verification
We present a scoring approach for speaker verification that mimics the standard PLDA-
based backend process used in most current speaker verification systems. However, unlike …

System combination using auxiliary information for speaker verification
L Ferrer, M Graciarena, A Zymnis… - 2008 IEEE International …, 2008 - ieeexplore.ieee.org
Recent studies in speaker recognition have shown that score-level combination of
subsystems can yield significant performance gains over individual subsystems. We explore …

Reliability estimation of the speaker verification decisions using Bayesian networks to combine information from multiple speech quality measures
In some situations the quality of the signals involved in a speaker verification trial is not as
good as needed to take a reliable decision. In this work, we use Bayesian networks to model …

Using post-classifiers to enhance fusion of low-and high-level speaker recognition
YA Solewicz, M Koppel - IEEE Transactions on Audio, Speech …, 2007 - ieeexplore.ieee.org
This paper proposes a method for automatic correction of bias in speaker recognition
systems, especially fusion-based systems. The method is based on a post-classifier which …
