The Blizzard Challenge 2018 was the fourteenth annual Blizzard Challenge and is the twelfth consecutive one organised at the University of Edinburgh, with support from the other members of the Blizzard Challenge committee. The task this year was the same as in 2016 and 2017, and used identical data to 2017: a single-speaker English corpus, comprising around 6.5 hours of audio from 56 professionally-produced children’s audiobooks.
