Somewhere around the third paragraph of a long article, attention starts to drift. The eyes move but the mind has already moved on, to the next tab, the next thought, the ambient pull of everything else. We call this reading, though it looks more like scanning. What we lose, when we skim, is the sentence itself: its architecture, its timing, its small payoffs buried in the middle clauses.
There is a case that the voice fixes this. Not because audio is superior to text, but because hearing requires you to stay. A sentence spoken cannot be skimmed. It arrives in sequence, asks for sequence in return. Research on dual-channel learning, text seen and heard simultaneously, suggests comprehension improves when both channels carry the same meaning. Retention, too. The ideas have somewhere to land.
What you are reading right now could also be something you are listening to. That is not a hypothetical. It is, with one click, just an option, and the article you actually finish is the one you actually read.
