As a session chair recently, I was to introduce a talk where the title of the talk was ungrammatical (in both the abstract and talk slides), likely due to the presenter not being a native English speaker. Two words should have been in plural when they were not, which became clear after reading the abstract.
I faced a dilemma:
read the corrected title, and possibly embarrass the speaker (possibly putting them off their talk), or
deliberately read the ungrammatical title.
I attempted a compromise: I acted casual, as if I wasn't reading the title word for word.
Question: How should the session chair introduce presentation titles which are ungrammatical?
I'm just wondering what's the best solution in this situation (or perhaps what I did "on the fly" was the best).
