Call for participation

The Blizzard Challenge 2010 Workshop is the culmination of the Blizzard Challenge 2010 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 SSW7

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 2010 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 30th July 2010.

Location and date


Saturday 25th September 2010 (all day)


The location is the same as SSW7 - the ATR building in Kansai Science City, near Kyoto, Japan.

The shuttle bus provided during SSW7 from Nara Washington Hotel Plaza to the venue will also operate on the day of the Blizzard workshop.


The workshop format is single-track with oral presentations from the participants in the Challenge, the organisers and invited speakers.

Each system presentation should last for a maximum of 15 minutes, including time for questions. Presenters should bear in mind that the audience will mainly comprise speech synthesis experts; therefore presentations do not need to include extensive background material.

We will start at 9am and run until around 6pm. The programme is as follows:
