1
Write for the ear
Give Omnivoice a short, complete passage rather than a dense block of notes. Expand ambiguous abbreviations, check names, and add punctuation where a listener should hear a sentence break. Clear input makes it easier to identify whether an awkward moment comes from the writing or the rendering.
2
Match delivery to purpose
A calm explainer, a lively introduction, and a careful set of instructions call for different pacing. If the available experience offers voice or delivery choices, compare them against the same passage instead of changing the copy and the voice at once. That keeps the listening test meaningful.
3
Listen, then revise
Play the result all the way through. Mark mispronounced names, unnatural emphasis, rushed transitions, and sentences that are hard to follow without seeing the text. Edit the script and check it again; a convincing opening does not guarantee that the rest of the passage works.
