How to Write a Voice Over Script That Doesn’t Kill the Performance

I’ve recorded a lot of scripts. The ones that come in well-written are a genuine pleasure. The ones that don’t are a different kind of experience, where the best take of the session is still fighting uphill against sentences that don’t breathe.

Nobody talks about this. The conversation about voice over is almost always about the talent, the gear, the direction. Rarely about the copy. But the copy is where a lot of projects quietly fail before a single word gets recorded.

Here’s what I’ve learned from 30 years on the mic about what makes a VO script work.

Write It to Be Heard, Not Read

The most common mistake in VO copy is writing for the eye instead of the ear. Just because a sentence looks clean on paper doesn’t mean it will sound natural coming out of someone’s mouth.

Test: read your script aloud. Not in your head. Out loud, at normal speaking pace. If you stumble anywhere, that’s the script’s problem, not your reading. If a sentence requires you to take a breath in a weird place, it needs to be restructured. If you get to the end of a thought and you’re not sure where it landed, the copy isn’t clear enough for audio.

Voice over doesn’t have punctuation as a visual guide. The voice actor can create a pause or a lean or a drop in pitch, but only if the words make that possible. Give them sentences that have natural rhythm and natural breathing room.

Keep Sentences Short and Punchy

Long sentences compound in audio. By the time the listener gets to the end, they’ve forgotten the beginning. Short sentences land. They create space. They let the voice actor put weight on what matters.

This doesn’t mean every sentence has to be four words. It means the average sentence in your script should be shorter than you think it needs to be. If a sentence has three subordinate clauses, break it into three sentences.

Cut the Setup, Start With the Thing

“In today’s fast-paced world, it can be difficult to find the time to…”

Nobody says that. In a commercial, you have five seconds before someone’s mind drifts. Start with the point. Start with the thing that matters. The setup can be earned once you’ve got them, not before.

Same goes for corporate narration. “Welcome to this training module on…” is dead air with words. Drop the welcome. Tell them what they’re about to learn and why it matters to them, in that order.

Avoid the Words That Die on Mic

Some words look fine in print and land flat in audio. “Solution.” “Innovative.” “Seamlessly.” “Cutting-edge.” These words have been in so many scripts that they don’t mean anything anymore. A voice actor can deliver them perfectly and they still don’t land because the listener’s brain skips them. They’re the audio equivalent of a pop-up ad.

Replace them with specifics. Not “innovative solutions” but “software that cuts your billing time in half.” Not “seamless experience” but “no hold music, no transfer, just someone who picks up.” Specific language gives the voice actor something to hold onto. It gives the listener something to remember.

Tell the Voice Actor How It Should Feel

The best briefs I get don’t just describe the audience. They describe the feeling. “We want this to feel like advice from a friend who happened to go to medical school.” That’s something I can record. “Professional but approachable” tells me almost nothing.

Think about the emotional state you want the listener to be in by the end of the spot. Confident? Reassured? Curious? Ready to act? Work backward from that feeling and make sure the copy earns it.

One More Thing

If you’re not sure whether your script is working, send it to your voice talent before the session. A good voice actor will read it through and flag anything that’s going to be a problem. This takes five minutes and can save a resession. Most of us are happy to do it because it means the work goes better for everyone.

If you’ve got a script and you want a quick read on whether it’ll work, send it here.
