Do I make sense?

I’d had a video automatically transcribed. I presume all kinds of AI jiggery-pokery had gone into turning audio frequencies into text—it was clear that the transcription engine was aware that a lot of hemming and hawing could be deleted, on the other hand not-quite-silences could be extrapolated into what probably was being said. A few times this worked amazingly well, but all too often the resulting text was nonsense. I was going to blame this on the lack of deep understanding on the part of the transcription engine, but as I replayed and replayed the same five second clip, trying to hear what was being said, by myself, I came to wonder: Is this actually what my students hear when I lecture—words that may be grammatically correctly connected, but rarely make any sense?
