Submissions and listening test results from previous Blizzard Challenges
These distributions include the synthetic speech submitted by participants in the challenge along with listeners' scores for the subset synthetic speech used in the listening test. Possible uses of these materials include:- Re-running the challenge, such as with a subset of the systems plus a new system
- Development of instrumental (objective signal-based) measures of synthetic speech naturalness, speaker similarity or intelligibility
- Development of synthetic speech detectors for use as an anti-spoofing countermeasure against attacks on speaker identification systems
