We are pleased to announce the Zero Resource Speech Challenge 2020, which has been submitted as a special session at Interspeech 2020. ZeroSpeech 2020 is a consolidating challenge in which participants submit systems to the Zero Resource 2017 (Track 1 or Track 2) or the Zero Resource 2019 tasks. Participants are particularly encouraged to submit to multiple tracks/challenges (unit discovery evaluated on both the 2017 and 2019 evaluations, unit discovery used as a basis for spoken term discovery).

• Training data. The training data available will be exactly the same as in the 2017 and 2019 challenges, separated into the same development and surprise languages. Participants interested in starting work immediately are encouraged to begin by obtaining the existing development kits and datasets. Please see ZeroSpeech 2017 and ZeroSpeech 2019: TTS without T to get started.

• Test data and evaluation. The test data and evaluations will undergo some minor modifications (such as bug fixes). Updated kits will be available in early 2020.

• Sign-up, submission procedure, and leaderboard. The challenge will again be run again on Codalab, with a leaderboard allowing for comparison between 2017/2019 evaluations for combined submissions.
