This package is part of the signal-processing and machine learning toolbox Bob. This package contains an interface for the evaluation protocol of the 2012 NIST Speaker Recognition Evaluation. This package does not contain the original NIST SRE databases, which need to be obtained through the link above.

Complete Bob's installation instructions. Then, to install this package, run:

$ conda install bob.db.nist_sre12

You can either download the SQLite DB file

1. To download a copy of an already populated SQLite DB

./bin/bob_dbmanage.py nist_sre12 download

2. To generate and populate the NIST SRE 2012 database do the following:

• Change to sre12 file list directory:

  cd bob/db/nist_sre12/sre12

• Create file lists and key files for NIST SRE 2012 protocols and conditions

  ./generate-file-lists.py

• You can check that file lists point to actual files by running

  ./check-all-files-exist.py

  after assigning variable 'prefix' your SRE12 base path

  prefix='DATABASE_DIRECTORY_PREFIX'

• Populate SQL database

  ./bin/bob_dbmanage.py nist_sre12 create -vv -R

3. To double check the files in the SQLite database point to actual files

./bin/bob_dbmanage.py nist_sre12 checkfiles -e .sph -d DATABASE_DIRECTORY_PREFIX
