The Blizzard Challenge 2005

In order to better understand different speech synthesis techniques on the same data, we have devised a challenge that will help us better compare research techniques in building corpus-based speech synthesizers.

The basic challenge is to take the publicly available CMU ARCTIC speech databases and build a synthetic voice. Unknown sentences from an independent source will be generated and each participant will synthesize them with their system. The speech will then be put on the web for evaluation. The results were presented at a special session at Interspeech 2005 -- Eurospeech in Lisboa.
