The International Conference on Spoken Language Translation (IWSLT) 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, as well as scientific papers on 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 references for all researchers and practitioners working in speech translation and related fields.

Many challenges in speech translation have not yet been addressed; among them, we are really interested in topics related to new application scenarios (e.g. meetings, subtitling, dubbing), specific aspects (e.g. names, accents), different styles, multilingually, discourse and summarization, multimodal and multi-party speech translation, and 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 to be 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 and send it to: iwslt-organizers@googlegroups.com by September 30th, 2026. Decisions about which tasks will run in 2027 will be announced by November 1st, 2026.
