Introduction

This corpus, which is a subset of the Switchboard-1 (LDC93S7) corpus, was used in NISTs 1996 Speaker Recognition Evaluation. The focus of this evaluation was on detection of the presence of a hypothesized target speaker, given a segment of conversational speech over the telephone.

Data

The corpus consists of one Development Data disc and two Evaluation Data discs. Both sets include training and test segments.

The Development Data includes both training and test segments for about 45 male and 45 female speakers. The training data consists of about four one minute segments of speech data for each target speaker. The test data contains shorter segments of speech data (three, 10, and 30 seconds) that were taken from different conversations for each speaker.

The Evaluation Data includes about 20 male and 20 female target speakers and 200 male and 200 female non-target speakers. All of these speakers are different from the speakers in the Development Data set. Training data is supplied for each of the target speakers, in the same manner as the Development Data. Test data is supplied for both the target and the non-target speakers, in the same manner as the Development Data.
