A Cohort Methods for Score Normalization in Speaker Verification System, Acceleration of On-line Cohort Methods
Original language description
This paper deals with several cohort methods for score normalization in speaker verification systems. At first, the reasons for score normalization are provided. Next, the principle of score normalization techniques based on Bayesian theorem are explained. A new normalization technique, unconstraint cohort extrapolated normalization, is introduced. Experiments on NIST 2002 corpus were performed. Finally, there is a discussion about time consumption of the on-line methods. An improvement for accelerationof these methods are proposed. The results of experiments on NIST 2002 data set showed same significant improvements of cohort and proposed cohort extrapolated normalization in comparison with the standard world normalization.

Czech description
Tento článek pojednává o kohortních metodách pro normalizaci skóre. Nastinuje důvody a principy normalizace,které jsou dále otestovány společně s novou navrženou metodou normalizace na korpusu Nist2002. On-line metody vykazují velkou časovou náročnost, proto bylo navrženo urychlení.
