For the Blizzard Challenge 2007, ATR-SLC ( http://www.slc.atr.jp/) will release a newly-recorded eight-hour American English speech database. Unknown sentences from an independent source will be generated and each participant will synthesize them with their system. The synthesised speech will then be put on the web for evaluation.

The results will be presented at a satellite event at The ISCA 6th Speech Synthesis Workshop, in Bonn. Participants will be expected to submit 4 page papers describing their entries for review. Accepted papers will be presented at the workshop, and published on the Blizzard website.

The Blizzard Challenge 2007: Registration
