The Speech Synthesis Workshop or SSW is a satellite workshop to Interspeech. It used to be held every three years, but after 2019 it was decided to organize it every two years due to the fast pace of technological innovations. Typically, there will be a call for bids to organize SSW on the mailing list about 3 years ahead of time, and if there is more than one bid, there will be a voting round to pick the next one.

The Blizzard Challenge has been devised in order to better understand and compare research techniques in building corpus-based speech synthesizers on the same data. 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.
The Blizzard Challenge used to be an annual event, but now it is colocated with SSW. The SSW organizers will also organize the Blizzard Challenge, but they should connect with Simon King from CSTR in Edinburgh to develop the challenge and figure out the data set and evaluation tests used.
There is a Google group for discussion and announcements of the challenge:

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. The corpora used in a few of the previous Challenges are also available.
