Ad voiceovers without the studio booking
For a local bakery, a Shopify store or a real estate team, hiring a voice actor for every promo isn’t always realistic. Sales change weekly, product photos get updated and holiday campaigns come and go. An AI commercial voiceover lets you write a spot in the morning, test two versions by lunch and have it running in your ads by the afternoon.
Because the voice is generated from text, you can also produce variations for A/B testing: one ad that leads with price, another that leads with the benefit, each read by the same voice so the only difference is the message.

- 15-second social ad (Shopify store): “Your dog deserves a better bed. Our orthopedic memory-foam beds are made in North Carolina and ship free. Shop now at CozyPaws dot com!”
- 30-second local radio spot (restaurant): “Craving real Texas barbecue? Smokey Joe’s on Route nine is slow-smoking brisket for fourteen hours, every single day. Bring the family this weekend; kids eat free on Sundays. Smokey Joe’s. Come hungry, leave happy.”
- Real estate listing video: “Welcome to forty-two Maple Lane. Three bedrooms, two baths, and a backyard made for summer cookouts, just minutes from downtown Charlotte. Schedule your private tour today.”
- Seasonal sale: “The Black Friday sale starts now! Take thirty percent off everything in store and online, through Monday only.”
- App install ad: “Budgeting doesn’t have to be boring. Track every dollar in one tap. Download BrightBudget free today.”
How to create an AI commercial voiceover
- Time your scriptA 15-second spot is about 35–40 words; a 30-second spot is about 70–80 words; a 60-second spot is about 150 words. Read it aloud with a timer.
- Choose a voice that sells your brandPreview voices for energy and warmth. Try the trailer-style AI voice for big, dramatic launches.
- Shape the deliveryUse exclamation marks for excitement, semicolons for a measured pause before the offer, and adjust speed so the spot hits its length exactly.
- Generate, download and mixDownload the MP3, then layer it over music in your editor. Export to the format your ad platform or radio station requests.
Ad formats and voice tips
| Format | Typical length | Voice tip |
|---|---|---|
| TikTok, Reels and Shorts ads | 9–30 seconds | Fast, upbeat delivery; hook in the first line |
| YouTube pre-roll | 15–30 seconds | State the brand name in the first five seconds |
| Local radio and streaming audio | 30 or 60 seconds | Repeat the business name and location at least twice |
| Shopify and Amazon product videos | 30–90 seconds | Calm, clear voice focused on benefits and features |
| In-store and event announcements | 10–20 seconds | Slower speed with clear pauses for noisy spaces |
| Podcast ad inserts | 30–60 seconds | Conversational tone; avoid sounding like a hard sell |
Always check the specific technical requirements of your ad platform or radio station before you deliver audio.
