We describe the 2008 NIST Speaker Recognition Evaluation, including the speech data used, the test conditions included, the participants, and some of the performance results obtained. This evaluation was distinguished by including as part of the required test condition interview type speech as well as conversational telephone speech, and speech recorded over microphone channels as well as speech recorded over telephone lines. Notable was the relative consistency of best system performance obtained over the different speech types, including those involving different types in training and test. Some comparison with performance in prior evaluations is also discussed.
