*The International Conference on Spoken Language Translation*
*ACL – 22nd IWSLT 2025 – **Third** Call for Participation*
*31 July-1 August 2025 - Vienna, Austria*
http://iwslt.org
The International Conference on Spoken Language Translation (IWSLT)
<https://iwslt.org/> is the premier annual conference for all aspects of
Spoken Language Translation. Every year, the conference organises and
sponsors open evaluation campaigns around key challenges in simultaneous
and consecutive translation, under real-time/low latency or offline
conditions and under low-resource or multilingual constraints. System
descriptions and results from participants’ systems and scientific papers
related to key algorithmic advances and best practices are presented.
IWSLT is the venue of the SIGSLTs <https://iwslt.org/sigslt/>, the Special
Interest Group on Spoken Language Translation <https://iwslt.org/sigslt/>
of ACL <https://www.aclweb.org/portal/>, ISCA <https://www.isca-speech.org/>
and ELRA <https://www.elra.info/>. With a track record of 21 years, IWSLT
benchmarks and proceedings serve as reference for all researchers and
practitioners working on speech translation and related fields.
The 22nd edition of IWSLT will be run as a hybrid ELRA
<https://www.elra.info/>/ACL <https://www.aclweb.org/portal/> event,
co-located with ACL 2025 <https://2025.aclweb.org/> from 31 July to 1
August 2025.
*Important Dates*
*January 1, 2025*: Release of shared task training and dev data
*March 15, 2025*: Scientific paper submission deadline
*Apr 1-15, 2025*: Evaluation period
*April 21, 2025*: System description paper and demo submission deadline
*May 15, 2025*: Notification of acceptance
*June 1, 2025*: Camera-ready deadline (all paper)
*July 31-Aug 1*, *2025*: IWSLT conference
*Evaluation*
The IWSLT 2025 features shared tasks <https://iwslt.org/2025/#shared-tasks>
that address the following focus areas:
- High-resource ST: Offline track, Simultaneous track, Subtitling track, Model
compression track
- Low-resource ST: Low-resource and Indic (multilingual) tracks
- Instruction-following Speech Processing track: Technical domain ST, ASR,
Summarization, and QA
Training and development data for each shared task will be prepared and
released by the respective organisers (for further information on this
initiative, please refer to the IWSLT website <https://iwslt.org/2025/>).
Participants will receive instructions about how to submit their runs. In
addition, participants have the opportunity to present their work
through a system
paper that will be published in the ACL Proceedings.
*Conference*
IWSLT also 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 (to be announced on the website <https://iwslt.org/2025/>).
We will also accept commitments of submissions with reviews from the ACL
Rolling Review.
Additionally, to foster cross-pollination of ideas, 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.,
Findings for the *ACL, speech, NLP or MT conferences). Submissions for this
category will be accepted through a dedicated form (to be announced on the
website <https://iwslt.org/2025/>). Papers will be checked for relevance to
IWSLT, and assigned either oral or poster presentation slots if selected.
*Demo Session*
We invite researchers, practitioners, and industry professionals to
participate in an engaging demo session highlighting innovative systems,
tools, and component technologies that advance the field of speech
translation. The session will include live and interactive system
demonstrations to foster discussion and knowledge exchange among
participants across the field.
For more information, please see our Call for Demos
<https://iwslt.org/2025/call-for-demos>.

questions related to the shared tasks.

Dear all,
The International Conference on Spoken Language Translation (IWSLT)
<https://iwslt.org/> is the premier annual conference for all aspects of
Spoken Language Translation. Every year, the conference organizes and
sponsors open evaluation campaigns around key challenges in simultaneous
and consecutive translation, under real-time/low latency or offline
conditions, and for a variety of languages in under-resourced or
multilingual conditions. System descriptions and results from participants’
systems and scientific papers related to key algorithmic advances and best
practices are presented.
IWSLT is the venue of the SIGSLT, the Special Interest Group on Spoken
Language Translation of ACL, ISCA, and ELRA. With a track record of 20+
years, IWSLT benchmarks and proceedings serve as a reference for all
researchers and practitioners working on speech translation and related
fields.
There are many challenges in speech translation that have not yet been
addressed, among them, we are really interested in topics related to new
applications scenarios (e.g. meetings, subtitling, dubbing), specific
aspects (e.g. names, accents), different styles, multilingually, discourse
and summarization, multimodal and multi-party speech translation, automatic
evaluation metrics for speech translation. or many other ideas that
researchers have not yet focused on. Therefore, we invite proposals for
shared tasks. As a task organizer you can promote a particular challenge in
speech translation, either newly identified or worthy of continued
research. For those proposing new tasks, for inspiration, you can find the
tasks run in the previous year on the IWSLT website. Tasks will be
selected in November based on their relevance and readiness for the
evaluation campaign, to enable data released by the end of the year. To
ensure an appropriate number of total tracks, highly related proposals may
be encouraged to merge after initial review.
If you want to propose a new task to encourage researchers around the world
to work on particular timely challenges in SLT, please fill out the
following form <https://iwslt.org/assets/pdfs/IWSLT2026-Call_for_Tasks.pdf>
and send it to: *iwslt-organizers(a)googlegroups.com
<iwslt-organizers(a)googlegroups.com> *by* September 30th, 2025. *Decisions
about which tasks will run in 2026 will be announced by *November 1st, 2025*
.
