Special Session: Recent Highlights in SLT

IWSLT 2024 will introduce a special session entitled “SLT Recent Highlights”. The session intends to provide an overview of recent highlights from the field across venues, with a series of short presentations focused reviews on recent developments and new/emerging trends. Additionally, a short and lively discussion may follow the presentations. We believe this initiative will contribute to a better understanding of the current landscape of SLT research and foster collaboration and exchange of ideas within the IWSLT community.

For more information, see here: Special Session: Recent Highlights in SLT.

Paper Submission

Submissions should be scientific papers or evaluation campaign system description papers. All papers may consist of 4 to 8 pages of content with additional pages of references, formatted using the ACL stylesheets. Upon acceptance, all papers will be given one (1) additional content page to address reviewers’ comments. Accepted papers will be published in the ACL Anthology and will be presented at the IWSLT conference either orally or as a poster.

Please submit all papers through the IWSLT’24 submission portal.


  • Scientific papers must be anonymized for submission, while system description papers do not need to be.
  • We accept submissions which have previously been made available as technical reports or preprints, e.g. on arXiv.
  • We will not accept scientific papers for publication that overlap significantly in content or results with papers published elsewhere.
  • Scientific papers which have been, or plan to be, submitted to other venues must be declared as such at the time of submission, and must be withdrawn from the other venues if accepted and published at IWSLT 2024.
  • Scientific papers whose first author is a student will be eligible for the IWSLT 2024 Best Student Paper Award (authors should note eligibility in the paper submission form).
  • Limitations and Ethics Statement sections (see the ACL’23 call for papers for more details) are encouraged but not required. If included, they should be placed after the conclusion for submission and will not count against the page limit.
