The 2019 NIST speaker recognition evaluation (SRE19) is the latest in an ongoing series of speaker recognition evaluations conducted by NIST since 1996. These evaluations serve:

  • to explore promising new ideas in speaker recognition
  • to support the development of advanced technologies incorporating these ideas
  • to measure and calibrate the performance of the state-of-the-art speaker recognition systems

They are intended to be of interest to all researchers working on the general problem of text-independent speaker recognition. To this end the evaluation is designed to be simple, to focus on core technology issues, to be fully supported, and to be accessible to those wishing to participate.
The basic task in NIST SREs is speaker detection, i.e., determining whether a specified target speaker is speaking during a given segment of speech. SRE19 will consist of two separate activities: 1) a leaderboard-style challenge using conversational telephone speech (CTS) extracted from the unexposed portions of the Call My Net 2 (CMN2) corpus, and 2) a regular evaluation using audio-visual material extracted from the unexposed portions of the Video Annotation for Speech Technology (VAST) corpus. For more information about SRE19 please visit the announcement page or send questions to speaker_poc@nist.gov.
