Paper Abstract

From 1996 through 2008, the NIST Speaker Recognition Evaluations have focused on the task of automatic speaker detection based on recorded segments of spontaneous conversational speech. Earlier evaluations were limited to English language telephone speech. More recent evaluations (2004-2008) have included some conversational telephone speech in multiple languages, with the 2008 evaluation including 24 different languages. These recent evaluations have also explored cross channel effects by including phone conversations recorded over multiple microphone channels, and the 2008 evaluation also examined interview type speech recorded over multiple microphone channels. The considerable progress observed over the period of these evaluations has made the technology potentially useful for detecting individuals of interest in certain applications. Performance capability is measurably affected by a number of situational factors, including the number and duration of the training speech segments available, the durations of the test speech segments available, the language(s) spoken in these segments, and the types and variability of the recording channels involved.
