AI Voices in Ads: TikTok, Meta and Google Disclosure Rules (2026)

You can use AI voices in ads on all three. TikTok requires you to label any ad whose audio is fully AI-generated. Meta and Google require disclosure in political and social-issue ads, and label AI content themselves in more and more places. Using a real person's voice or likeness without permission is refused everywhere.

Rules checked on 24 October 2026, from each platform's ad policies.

TikTok

TikTok allows AI-generated content in ads "if" you "apply the AIGC label, or" add "a clear disclaimer, caption, watermark, or sticker of your own". It covers "content that contains images, video, or audio that are completely AI-generated" and content "using AI voice-cloning", so an ad with an AI voiceover needs the label.

• Where: in Ads Manager, turn on "This ad contains AI-generated content" when you build the ad. It can't be changed after you submit.
• Spark Ads (boosted organic posts) follow TikTok's rules for organic posts instead.
• If you don't: "your ad will be rejected or restricted".
• Never: "misuse of the likeness (audio or visual) of a public figure".

Meta (Facebook and Instagram)

For political and social-issue ads, Meta requires you to disclose when you "use AI to create or edit photorealistic images, videos, or realistic audio". Failing to "may result in ad removal and account penalties". Since October 2025 Meta no longer runs those ads in the EU at all.

For other ads, Meta adds its own "AI info" label when it detects AI-made content, shown in "About this ad" and sometimes next to "Sponsored". We found no general rule asking advertisers to label an AI voiceover in an ordinary ad.

Google and YouTube ads

For election ads, tick "Altered or synthetic content". Google's own example of the disclosure is "This audio was computer generated."

In July 2026 Google added an AI label setting for ad assets, rolling out across its ad products, with the disclosure shown under "How this ad was made" and labels on the ad itself in the EU, India and New York. Google notes the setting "doesn't guarantee your compliance" with local law. For everything else, the general rule applies: "Manipulating media to deceive, defraud, or mislead others is not allowed."

What should I do in practice?

1. On TikTok, always turn on the AI label for ads with an AI voice.
2. For political or social-issue ads anywhere, disclose.
3. Never imitate a real person (a celebrity, a politician, a competitor's spokesperson) without written permission.
4. Keep the licence: use audio you're allowed to use commercially. On Leelo that's any paid plan.
5. In the EU, ads that make a real person appear to speak are deepfakes under the AI Act and must say so. A licensed AI voice reading your script isn't one.

Making the ad

A 30-second spot is about 70–80 words. Write it, generate it, and trim the lines that run long; make three versions with different voices and test them. Our voices for ads page compares four voices on the same spot, and ads and marketing covers making every version of a campaign in a day.

All platforms at once: can you use an AI voice on YouTube, Udemy, Audible, Spotify, Steam and TikTok?
