Why small teams use an AI voice for ads
Hiring a voice actor is still the right call for a flagship campaign. But most advertising is not a flagship campaign. It is this week’s offer, a new product colour, a retargeting video, or five versions of the same idea for testing. For that work, speed and volume matter more than a perfect performance.
An AI voice lets you:
- Test scripts cheaply. Generate three openings and run all three.
- Match voice to audience. Try a different voice for each market or segment.
- Update instantly. When the price or the date changes, regenerate one sentence.
- Stay consistent. Every ad in the campaign has the same voice, whenever it was made.
A structure that fits every length
15 seconds (about 35 words)
- Hook or offer: one sentence
- One reason to care
- Call to action
30 seconds (about 75 words)
- The problem, in the customer’s words
- The product as the answer
- One or two proofs: a feature, a number, a guarantee
- Call to action, said once clearly
60 seconds (about 150 words)
- A short story or scene the customer recognises
- The turn: what changes with the product
- Three benefits, most important first
- An objection, answered
- Call to action, with the brand name repeated
Writing lines that read well aloud
- Say prices and dates the way people say them: “nineteen ninety-nine”, “this Friday”.
- Put the brand name early and again at the end.
- Avoid tongue twisters. Read the script aloud once. If you trip, the voice may too.
- Keep legal lines short and put them in on-screen text where the platform allows it.
- One call to action. Two is the same as none.
Choosing the voice
| The ad is… | Look for a voice that is… | Preset |
|---|---|---|
| A sale or limited offer | Bright and urgent | Expressive |
| A premium or luxury product | Calm, low and unhurried | Narration |
| A how-it-works product demo | Clear and friendly | Natural |
| A local service | Warm and conversational | Natural |
| Aimed at children or families | Upbeat and gentle | Expressive |
Generate the first line in three candidates and play them back to back. The right one is usually obvious.
From audio to finished ad
Voice Labs produces the voiceover. To finish the ad, save or share the audio, import it into your video editor, and build the picture on top. Change shots on sentence breaks, keep the music low enough that every word is clear, and add captions, because many ads play without sound.
