Call for participation

The Blizzard Challenge 2015 Workshop is the culmination of the Blizzard Challenge 2015 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 Blizzard Challenge 2015 uses datasets from six Indian languages: Hindi, Tamil, Telugu, Marathi, Bengali and Malayalam, recorded by professional speakers in high quality studio environments.

The workshop is a satellite event of Interspeech 2015

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 and the Expert Committee.

Paper submission instructions

  • Use the Interspeech 2015 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 deadline given in the official timeline and we will notify you of acceptance within a week. If you need an earlier notification (e.g., in order to obtain travel permission from your employer), then please contact us.

Location and date

Date: Friday 11th September 2015 (all day)

Venue: The Blizzard Challenge 2015 Workshop will take place at the following address:

Quality and Usability Lab

Telekom Innovation Laboratories

TU Berlin

Ernst-Reuter-Platz 7

D-10587 Berlin, Germany



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

Each system presentation slot is 30 minutes and presenters should speak for 20-25 minutes to allow time for questions and changeover. Presenters should bear in mind that the audience will mainly comprise speech synthesis experts; therefore presentations do not need to include extensive background material, but should focus on technical detail and go deep in to the specifics of each system. Presentations must include plenty of working audio examples to illustrate the strengths and weaknesses of the system! Please bring your own laptop to present.

The venue this year has a strictly limited capacity, so all attendees must obtain tickets in advance from Eventbrite.
