Submissions

All challenge submissions must be made through the leaderboard website.

Both tracks of the challenge will have two submission and evaluation phases:

  1. Development phase: evaluations throughout the challenge runtime using intrusive and non-intrusive objective metrics on clean and synthesized noisy stimuli. You will be able to make multiple submissions corresponding to revisions of your work, and select which result to render in the leaderboard. Daily submission limits will apply, and will be displayed on the leaderboard website. Please refer to Get Started pages for the track specific information (track1, track2) regarding submission format, folder structure etc.
  2. Blind test phase: evaluation at the challenge completion using crowdsourced listening tests focused on evaluation of both speech quality and intelligibility. We allow multiple submission during this phase for revisions and corrections, but only the latest submission will be evaluated through crowdsourced listening tests. Each test phase submission must include a system description paper of at least two pages (plus references), along with audio files. Teams participating in both tracks may submit either a combined system description paper or separate papers for each track. If submitting a combined paper, it must be included with the submission for each track.
