How to Write a Voiceover Script that Sounds Natural

A great voice can only do so much with a script written for the page. Words that look fine in a brochure can sound stiff, rushed or confusing when spoken. This guide shows you how to write a voiceover script that sounds natural, fits your timing and gives your voice artist everything they need.

Write for the Ear, Not the Eye

Listeners cannot re-read a sentence, so every line has to land the first time.

• Keep sentences short. One idea per sentence is easier to say and easier to follow.
• Use everyday words. Say "help" rather than "facilitate" and "buy" rather than "purchase".
• Sound conversational. Write the way people actually talk, including the short forms of words people use every day.
• Avoid tongue twisters. Read the script aloud and rewrite anything you stumble over.
• Repeat what matters. In radio and on hold, repeat the business name and call to action.

Words-Per-Minute Timing

As a guide, a natural read runs at roughly 150 words per minute, or about 2.5 words per second. Allow fewer words when there is music, sound effects or a pause for a logo. Common guides:

• 15-second ad: around 30 to 35 words
• 30-second ad: around 65 to 75 words
• 60-second ad: around 140 to 150 words

Our radio ad script guide goes deeper on word counts for radio. For TV, corporate and eLearning narration, time the script against the visuals and leave room for on-screen text.

Formatting and Pronunciation Guides

• Use a clean layout. Double-spaced, numbered lines or paragraphs make pick-ups easy.
• Spell out numbers the way they should be read. Write "1800 086 183" as you want it spoken, and say whether "2026" is "twenty twenty-six".
• Add a pronunciation guide. List brand names, place names, people and technical terms with phonetic spellings, such as "Quay (KEY)".
• Mark emphasis sparingly. Bold or underline only the words that truly need weight.
• Separate directions from copy. Put notes in brackets or a separate column so they are never read aloud.

Give Clear Tone Direction

Tell the voice artist who they are talking to and how it should feel. Useful notes include:

• The audience, such as small business owners, new staff or families
• Three words for the tone, such as warm, confident and friendly
• Pace, such as relaxed, upbeat or measured
• A reference, such as "like a helpful local, not a salesperson"

Common Script Mistakes

1. Too many words for the time available, which forces a rushed read.
2. Long lists of features that listeners cannot remember.
3. Unclear call to action, or more than one.
4. Jargon and acronyms the audience does not use.
5. Late changes after recording, which may need a new session.
