Bulk ad voiceovers: let Ultron write ten and voice them

The fastest way to find a winning ad is to test ten at once, not agonize over one.

The fastest way to find a winning ad is to test ten at once, not agonize over one.

Most ad voiceovers either cost a fortune at a studio or sound like a robot reading a receipt. Ultron skips both. It writes the scripts in ten different angles, then generates the actual voiceovers with real emotion baked in, so you can test a bunch and run the winner. Studio quality, no studio.

What Ultron does

  • Writes ten ad reads in ten different angles.
  • Generates the voiceover for each one with the emotion you direct, so the ads sound human, not synthetic.

Step 1, the ad-script prompt

Give Ultron your product details and this brief:

Prompt
You are a direct-response copywriter. Here is my product and my offer: [paste yours here]. Write me 10 ad voiceover scripts, each 15 to 30 seconds when read out loud, in 10 different angles: urgent, calm and trustworthy, funny, aimed at a younger audience, problem-first, social proof, bold claim, mini story, question hook, and straight offer. For each one, mark exactly where the read should get more energy or drop to a near-whisper.

Step 2, generate the voiceovers

Once you approve the scripts, Ultron generates the audio itself, no extra apps:

Prompt
For each of the 10 ad scripts above, generate a voiceover, keep the emotion direction inline so the reads are not flat, and save them as numbered audio files I can listen through.

Step 3, make it sound human

The difference between obviously synthetic and wait-that-is-a-real-ad is the emotion. You direct the feeling straight in the script:

  • More energy on the hook to grab attention.
  • Drop to a near-whisper on the close to pull people in.

Ultron performs the direction instead of reading flat, so every one of your ten reads has real energy.

3 things to run next

3 things to run next3 prompts
1

Localize a winner

Rewrite my top 3 ad reads for [country or market], adjusting the slang, references, and tone so they sound native, then regenerate the voiceovers.

2

Scroll-stopping hooks

Give me 15 different opening lines for this ad, each under 4 seconds, designed to stop the scroll. Mark the read direction for each.

3

Pick what to test first

Based on my product and audience, rank these 10 ad angles by which is most likely to convert, and tell me which 3 to test first and why.

How to get the most out of it

  • New to this: generate just 3 reads first, not 10, and listen back so you can hear the difference the emotion direction makes.
  • Already running ads: feed Ultron your current best ad and ask for 10 variations on that winner, then test them head to head.

The honest part

Generated voiceovers are genuinely good now, but they are not magic. The script still has to be a good ad, which is exactly why Ultron writes ten angles instead of one, so you can test and let the winner emerge. Always listen back before you publish, your own ear is the final check.
