31 July-1 August 2025 - Vienna, Austria

The International Conference on Spoken Language Translation (IWSLT) is an annual scientific conference, associated with shared tasks on spoken language translation, where both scientific papers and system descriptions are presented.

The 22nd edition of IWSLT will be run as an ACL and ELRA sponsored event, co-located with ACL 2025 in Vienna, Austria on 31 July-1 August 2025. It will be run as a hybrid event.

Shared Tasks

IWSLT 2025 will host the following shared tasks:

High-resource ST

Low-resource ST

Instruction-Following Speech Processing

All tasks will follow the same schedule (below). For updates, please join IWSLT Evaluation Campaign google group.

Registration

Registration for the 2025 Evaluation Campaign will open later this year.

Please join the IWSLT Evaluation Campaign google group for periodic updates and community questions.

Paper Submission

The submission portal will open in early 2025.

IWSLT invites submissions of scientific papers to be published in the ACL Proceedings and presented either in oral or poster format. The conference selects high-quality, original contributions on theoretical and practical issues of spoken language translation research, technologies and applications. Submissions will be accepted directly through the IWSLT submission site. We also accept commitments of fully-reviewed papers from ACL Rolling Review (commitment deadline to come).

Shared task participants also have the opportunity to publish and present their work through a system description paper that will be published in the ACL Proceedings and presented at the conference. Papers should be submitted for review directly through the IWSLT submission site.

Additionally, to foster cross-pollination of ideas and further community discussion, the conference also invites the presentation of papers on speech translation recently published elsewhere. Please note that this is for non-archival presentation of papers relevant to speech translation already published in other venues (e.g., ACL 2025 Findings papers, or other speech, NLP, or MT conferences). Submissions for this category will be accepted through a dedicated form (to be linked here in spring 2025). Papers will be checked for relevance to IWSLT, and assigned either oral or poster presentation slots if selected.

Submission requirements

  • 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.
  • 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 (though these may be presented at the conference as described above)
  • 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 2025.
  • Scientific papers whose first author is a student will be eligible for the IWSLT 2025 Best Student Paper Award (authors should note eligibility in the paper submission form).
  • Limitations and Ethics Statement sections (see the ACL 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.
