How do I narrate a deck without sounding like a robot?

Natural narration starts with script quality and pacing, not just voice model selection.

Write as you speak, not as you write documents. Use short sentences, contractions, and direct wording. Long, clause-heavy copy is the main reason generated voice sounds synthetic. Keep each narration block focused on one idea so cadence stays steady.

Then tune delivery by slide type. Intro and summary slides usually work at normal pace, while technical or pricing slides often need slower delivery. Small pace adjustments can improve comprehension more than swapping voices repeatedly.

Pronunciation matters too. Add pronunciation hints for brand names, acronyms, and product terms. Without this, even high-quality models can misread critical words and break trust.

Finally, review in the context viewers will hear it. Test on laptop speakers and mobile headphones. A voice that sounds acceptable in studio-like conditions can feel harsh or rushed on mobile.
