The International Conference on Spoken Language Translation

ACL – 20th IWSLT 2023

July 13-14, 2023 – Toronto, Canada

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 under low-resource or multilingual constraints. System descriptions and results from participants’ systems and scientific papers related to key algorithmic advances and best practice are presented.

IWSLT is the venue of the SIGSLTs, the Special Interest Group on Spoken Language Translation of ACL, ISCA and ELRA. With a track record of 19 years, IWSLT benchmarks and proceedings serve as reference for all researchers and practitioners working on speech translation and related fields.

In 2023, IWSLT will be co-located with ACL 2023 and will be run as a hybrid meeting.
