This directory (sre16) contains example scripts for the NIST SRE 2016 speaker recognition evaluation. The following corpora are required to perform the evaluation: NIST SRE 2016 enroll set NIST SRE 2016 test set More details on NIST SRE 2016 can be found at the url https://www.nist.gov/itl/iad/mig/speaker-recognition-evaluation-2016. 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 speaker recognition recipes. The recipe in v1 demonstrates a standard approach using a full-covariance GMM-UBM, iVectors, and a PLDA backend. The example in v2 demonstrates DNN speaker embeddings with a PLDA backend.
