Curriculum Vitae
Teaching
Theses / NPFL045 Ročníkový projekt / Individual Software Project
In 2026-2027, I am visiting researcher in Edinburgh, so my availability is limited.
But, I can supervise Bc. or Master theses and individual software project (NPFL045 Ročníkový projekt).
I am interested especially in human-to-human cross-lingual communication via simultaneous speech translation, human or automatic post-editing, confidence estimation, etc. I am open to students' ideas also in other NLP domains, especially if their topic is related to any of my publications.Invited lecture: Speech Translation (slides).
