In this paper we propose a new measure to classify speakers
with respect to their behaviour in speaker recognition
systems. Taking the proposal made by EAGLES as a point of
departure we show that it fails to yield results that are
consistent between closely related speaker recognition
methods and between different amounts of speech available
for the recognition task. We show that measures based on a
straightforward confusion matrices, that take only the 1-best
classification into account, cannot result in
consistent classifications. As an alternative we propose a
measure based on n-best scores in a speaker identification
paradigm, and show that it yields more consistent performance.
