REPORT Genoud-96.01/IDIAP Combining methods to improve speaker verification decision Genoud, Dominique Gravier, Guillaume Bimbot, Frédéric Chollet, Gérard EXTERNAL http://publications.idiap.ch/attachments/reports/1996/rr96-02.pdf PUBLIC Idiap-RR-02-1996 1996 IDIAP The aim of this paper is to describe how the combination of speaker verification algorithms with a priori decision thresholds can improve the overall robustness of a real application. The evaluation is performed in the context of a field application where each client is verified from a 7 digit pin code. This paper demonstrate that it is possible to increase the global performances of the system on combining the result of several algorithms.
