Is it fair to assume that comfort in speaking/oration correlates to reading comprehension?
I don't know that what you've described is any different now than 20 years ago when I was in high school. People struggled to read aloud texts like plays or classic literature. I would use that as a bar for complex prose that benefits from good narration; often the point was to encounter unfamiliar words or meter and to read with the purpose of critical analysis. A friend of mine is an author and we did a group reading of a play they'd written. Quite hard to do off the bat. Similarly if you've ever tried to DM a role-playing game like DnD, where the text you read is semi-randomly chosen based on what the characters decided to do (also, will you role-play dialog?).
I've worked in academia for 10+ years at this point. You can tell almost immediately if a presenter has had practice, knows their material or is comfortable speaking in public. Lecturers and professors are, unsurprisingly, often very comfortable giving presentations and there are people who live for conferences and working groups. We're required to read dense material frequently. Understanding of a piece of work, or the attention span required to ingest a scientific paper, does not necessarily mean you could read it aloud fluently.
