This directory contains example scripts for speaker diarization on a portion of CALLHOME used in the 2000 NIST speaker recognition evaluation. The 2000 NIST SRE is required, and has an LDC catalog number LDC2001S97. Additional data sources (mostly past NIST SREs, Switchboard, etc) are required to train the systems in the subdirectories. See the corresponding README.txt files in the subdirectories for more details. The subdirectories "v1" and so on are different diarization recipes. The recipe in v1 demonstrates a standard approach using iVectors, PLDA scoring and agglomerative hierarchical clustering.
