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 are then evaluated through listening tests.
Blizzard Challenge organisation describes how the challenge is organised, who runs it and tells you how you can get involved.
Blizzard Challenge Roadmap (UNDER CONSTRUCTION) is a long-term plan for the challenge, setting out some possible future challenges. This plan will be updated from time to time and your input is very welcome.
There is a mailing list for discussion and announcements for the challenge:
Participants must join the list by sending a message to email@example.com with the following line in the body of the message
Once you a member you will be able to mail messages to firstname.lastname@example.org

Tools and data
The tools for running your own Blizzard-style listening test and the submissions and listening test results from several previous Challenges are available for your own research. Please remember to acknowledge Blizzard whenever you publish work that makes use of these tools or data.
