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.
