Blizzard Challenge 2017
Read these first
This year, there are two distinct parts to the Blizzard Challenge. Teams may enter either one, or both. The first part of the challenge follows the standard approach of previous years, and comprises the single hub task (2017-EH1) which requires teams to build an end-to-end text-to-speech system. The second part of the challenge is novel and is designed to be accessible to the wider machine learning community; it comprises two spoke tasks (2017-ES1 and 2017-ES2)
- First, please read the calls for participation:
- Before participating, please read and agree to the rules for whichever part(s) of the challenge you are interested in
- You should only register for the challenge if you actually plan to submit an entry to the challenge
New: the Blizzard Machine Learning Challenge
Speech synthesis as a machine learning problem ---exploring new types of acoustic models
In the HMM era, by taking a unified view of both Automatic Speech Recognition (ASR) and Text-to-Speech (TTS), it was possible to develop various types of new ASR and TTS techniques, e.g., cross-lingual speaker adaptation, adaptive training for TTS, use of prosody in ASR, etc. We expect that by once again taking a unified view in the current DNN era, it will be possible to develop new types of acoustic modeling techniques that are useful for both ASR and TTS.
The series of Blizzard Challenges has helped us measure progress in TTS. But, to get competitive performance, a lot time has to be spent on skilled tasks such as updating the lexicon, removing inappropriate audio files, segmenting and aligning audio files, detecting alignment errors, etc. This may make the Blizzard Challenge unattractive to Machine Learning (ML) researchers from other fields.
We therefore propose a spin-off challenge that does not involve these speech-specific tasks, and allows participants to concentrate on the acoustic modeling task, framed as a straightforward ML problem, with a fixed data set.
The data that the organizers will provide is in the form of corresponding sequences of linguistic features, speech features and speech waveforms. Participants must train a model to predict speech features from linguistic features (or, to directly predict speech waveforms from linguistic features, as done in WaveNet), and then use that model to make predictions for a test set of previously-unseen linguistic features.
Evaluation will be done by the organisers, using a listening test, as in the main challenge.
Register by emailing firstname.lastname@example.org. We need to know your team name, the name of the main contact person, your affiliation, and contact details including email address, postal address and phone number. Please specify which task(s) you plan to submit entries for.
The speech + text data comes from professional audiobooks produced by Usborne Publishing.
- About 6.5 hours of British English speech data from a single female talker, which comprises 5 hours of speech already released for the 2016 challenge plus the audio from 6 additional books that were used for test material in 2016.
- Processed versions, such as alignments, are shared via the Blizzard Challenge 2016-7 Git Repository
- 2017-ES1 and 2017-ES2
- About 4 hours of British English speech data (waveforms) from a single female talker, which is a cleaned-up version of the data used in the 2016 challenge, along with linguistic features and speech features.

- available via : http://www.cstr.ed.ac.uk/projects/blizzard/, which include submitted synthetic speech and listener scores for some previous Blizzard Challenges, which may be helpful during development
- Download the questionnaire, complete it, and return it at the same time as your synthetic speech: http://data.cstr.ed.ac.uk/blizzard2017/system_questionnaire.txt
There is a mailing list for discussion and announcements for the challenge:
Participants must join the list by sending a message to email@example.com with the following line in the body of the message
Once you are a member you will be able to mail messages to firstname.lastname@example.org
The timeline shown on this web page is the official one and supercedes those shown in announcements - it is subject to change, but we will try to follow it as closely as possible. Note that we will not consider any requests from participants to change the synthetic speech submission date or the paper submission date!
