Summary

Following the success of the 2019 Conversational Telephone Speech (CTS) Speaker Recognition Challenge, which received 1347 submissions from 67 academic and industrial organizations, NIST is organizing a 2020 CTS Challenge, the next iteration of an ongoing series of speaker recognition evaluations conducted by NIST since 1996.

The basic task in the CTS Challenge is speaker detection, i.e., determining whether a specified target speaker is speaking during a given segment of speech. Similar to the 2019 CTS Challenge, the 2020 evaluation will feature a leaderboard-style challenge offering an open/unconstrained training condition, but using CTS recordings extracted from multiple data sources containing multilingual speech. In addition, unlike the 2019 CTS Challenge, no development set will be initially released.

For more information about the challenge please visit the announcement page or send questions to sre_poc@nist.gov.
