Blizzard Challenge 2012 Workshop

From SynSIG

The Blizzard Challenge 2011 workshop is generously supported by Google

Friday 14th September 2012

The workshop will be at the same venue as Interspeech 2012 - the Hilton Portland & Executive Tower.


Call for participation

The Blizzard Challenge 2012 Workshop is the culmination of the Blizzard Challenge 2012 which is an open speech synthesis evaluation campaign using common data sets and a large listening test. The aims of the workshop are to present the results from the listening tests and for participants in the Challenge to describe their systems.

The workshop is a satellite of Interspeech 2012

Who can attend the workshop ?

The workshop is open to all and we encourage participation from anyone interested in speech synthesis.

Who can submit a paper to the workshop ?

All participants in the Challenge are expected to submit a paper describing their entry (even if they cannot attend the workshop in person). Papers will be refereed by the Programme Committee.

Programme Committee

  • Simon King, University of Edinburgh, UK
  • Alan Black, Carnegie Mellon Univerisity, USA
  • Keiichi Tokuda, Nagoya Institute of Technology, Japan

Paper submission instructions

  • Use the Interspeech 2012 authors' kit, but your paper should be up to SIX pages in length
  • Remember that Blizzard is a scientific investigation - we are all trying to understand why some techniques work better than others.
  • With this in mind, please write a detailed, technical paper aimed at a specialist audience. Focus on analysis and evaluation. Try to explain WHY your system performed the way it did, and what makes it different from other systems. Explain why your system is designed in a particular way. For example, report internal evaluations you have done to select certain methods.
  • Submit your paper by email to by the 3rd August 2012 and we will notify you of acceptance by 10th August 2012. If you need an earlier notification (e.g., in order to obtain travel permission from your employer), then please contact us.
