NST researchers have organised the first Automatic Speaker Verification Spoofing and Countermeasures Challenge. The challenge has attracted more than 20 teams worldwide. The task of this year's challenge is spoofing detection, in particular to discriminate between natural and synthetic speech. The results of the challenge will be presented at Interspeech 2015 in Dresden, Germany. System description papers are available at the challenge website: http://www.spoofingchallenge.org.
