IWSLT 2021 will occur on two days, 5-6 August.
Day 1 will have a keynote, panels, and findings of the shared tasks
Day 2 will have Q&A sessions for presented papers

Q&A sessions with authors will be arranged as individual video sessions. Each session is organized within 5 1-hour timeslots to maximize convenience from different time zones. To allow authors to ask questions to other authors, we invite them to organize their time so to be available for Q&A during at least 50% of their 2 time slots. Hence, if you are not able to connect with an author during one time slot, please try with the next slot.

Q&A sessions: Full list of papers with videos, Q&A session links and times.


Note: Zoom link for Day 1 will be available on the ACL virtual site after registration to ACL-JCNLP 2021. Day 2 links are listed here.

Times are linked to a time converter site to view alternate time zones.
