Blizzard Challenge
From SynSIG
In order to better understand and compare research techniques in building corpus-based speech synthesizers on the same data, the Blizzard Challenge has been devised. The basic challenge is to take the released speech database, build a synthetic voice from the data and synthesize a prescribed set of test sentences. The sentences from each synthesizer will then be evaluated through listening tests.
This is now a regular series of challenges. The latest one is the Blizzard Challenge 2007. Descriptions of, and publications from, previous challenges can currently be found on the Festvox site.
