AI Voiceover Scripts for Video Ads: 12 Templates

Updated September 3, 2026

TL;DR: a 15-second spot is 35–40 words; a 30-second spot is 70–75. Every template below is written to be read aloud by an AI voice — short sentences, one idea each, a full stop before the call to action — and can be pasted straight into the video ads page widget.

Rules that make AI reads convert

15-second templates (35–40 words)

  1. Pain → fix: "Still losing an hour a day to notifications? [Product] puts everything on one screen and silences the rest. Try it free for a week. Link below."
  2. Before / after: "Last month, three tools and a spreadsheet. This month, [Product]. Same team, half the meetings. See how in thirty seconds. Link's in the description."
  3. Number hook: "Seventy percent of first drafts never ship. [Product] gets yours out the door today. Start free — no card, no setup."
  4. Question hook: "What if your podcast edited itself? [Product] cuts the silences, levels the voices, and exports in a click. Free to try."
  5. Offer-led: "[Product]: thirty percent off your first month, this week only. Tap to claim it before Sunday."
  6. Social-proof style: "Twelve thousand creators switched to [Product] this year. Find out why in a free trial. Link below."

30-second templates (70–75 words)

  1. Problem – agitate – solve: "You planned a video, then spent the evening fixing audio. Background hum, uneven levels, a mispronounced name in the last take. [Product] generates the voiceover in seconds, mastered and ready to drop into your edit. Change a line, regenerate a line. Start free, no card required. Link in the description."
  2. Demo walk-through: "Here's [Product] in real time. Paste the script. Pick a voice — this one's Leo. Hit generate. That's the file, already mastered for your platform. Need a different take? Change one word and run it again. Try it free today."
  3. Testimonial style (first person): "I run three faceless channels and I used to record every script myself. Now I paste, pick a voice, and publish. Same voice on every video, no re-records at midnight. If that's your week too, try [Product] — it's free to start."
  4. Comparison: "Most voice tools charge you twice: once to generate, again to fix. [Product] keeps every take, so a revision costs one paragraph. Commercial rights from six dollars a month. See the plans — link below."
  5. Launch: "Introducing [Product]. One workspace for text to speech, voice cloning and full audiobooks. Sixty voices to start, mastered output, and a free tier that's actually free. Available now — link in bio."
  6. Urgency + benefit: "This weekend only: every plan comes with double credits. That's two months of voiceovers for the price of one. Claim it at [brand] dot com before Monday."

Voices that carry an ad

Directing the read

Paste any template on the video ads page, pick a voice and generate. For a punchier take on an Ultra voice, put [excited] before the hook and [calm] before the offer, or write a one-line director's note: "upbeat, slightly faster, smile in the voice." Regenerate variants until one lands.

Frequently asked questions

How many words fit in a 30-second ad?

About 70–75 at a natural pace. If the read comes back long, cut adjectives before you cut the call to action.

Can I use these templates in paid ads?

Yes — the templates are free to adapt, and audio generated on any paid LeapFun plan includes commercial usage rights.

How do I make the voice sound less like an announcer?

Use a conversational voice such as Aria, write in first person with contractions, and on Ultra voices add a director's note describing the mood rather than the pace.

Can I A/B test hooks?

Generate the same body with different first sentences; each generation is billed separately. Draft on Leap Turbo at half price, finalise on Ultra.
