In the spring of 2010, the National Institute of Standards and Technology organized a Speaker Recognition Evaluation in which several factors believed to affect the performance of speaker recognition systems were explored. Among the factors considered in the evaluation were channel conditions, duration of training and test segments, number of training segments, and level of vocal effort. New cost function parameters emphasizing lower false alarm rates were used for two of the tests in the evaluation, and the reduction in false alarm rates exhibited by many of the systems suggests that the new measure may have helped to focus research on the low false alarm region of operation, which is important in many applications.
