Read scripts and spoken thought are not the same sound

The ear hears the difference immediately, even when it cannot name it.

Writing intended for the eye has a rhythm the voice cannot rescue. Its sentences are longer than breath, its clauses nest in ways that only make sense when you can see where they close, and its transitions rely on punctuation the listener never receives. Read aloud, this prose has a distinctive flatness: every phrase lands with the same weight because the reader already knows how the sentence ends. Listeners register the flatness as a kind of distance, and their attention drops well before they could explain why.

Spoken thought has a different shape. It builds in shorter units, doubles back to correct itself, arrives at a formulation rather than starting with one. This is often less elegant on the page and considerably more useful in the ear, because the listener is watching the idea take form and is therefore participating in it. The energy that a good explanation has in conversation and loses in transcription is exactly this energy, and it survives being planned, though not being written out sentence by sentence.

The middle path is to plan the structure tightly and the wording loosely: know exactly what has to be established and in what order, and let the sentences be found in the moment. That produces prose nobody would publish and explanation people follow. It also means accepting that a spoken piece will not be as compressed as a written one on the same material, because the compression that makes writing good is precisely what makes speech hard to follow. Different instruments, different tunings.
