Europe’s AI labelling rules started on 2 August 2026, and every week another creator asks the same thing: my video uses an AI voice, do I have to say so? The honest answer depends on two questions and one platform. Does the voice pretend to be a real person, does anything in the video fake something real, and where are you posting it. Here is the whole picture in one place, with the actual wording of each rule.

Eight rule sets, the two situations creators actually face, and what happens if you skip the label.
| Rule set | Plain AI narrator, your own script | Voice imitating a real person | If you skip it |
|---|---|---|---|
| EU AI Act (Article 50) | Usually no. A stock narrator is not a deep fake. | Yes. Disclose that it is AI generated or manipulated. | Fines up to 15 million euros or 3% of worldwide turnover |
| YouTube | No, unless something realistic is faked. | Yes. Switch on altered or synthetic content. | A label added for you, removal, or loss of the Partner Program |
| TikTok | Only if the video looks or sounds real. | Yes. Use the AI generated content label. | TikTok can apply the label itself; it reads Content Credentials |
| Facebook, Instagram, Threads | Yes. Meta asks for a label on realistic sounding audio that was digitally created. | Yes, and a more prominent label can be added. | Meta says it may apply penalties |
| Spotify (music) | Credits can show where AI was used. | Only with the artist's authorization. | Removal under the impersonation policy |
| Audible via ACX | AI narration is not accepted unless authorized. | Not accepted. | The title is rejected |
| China | Yes. Visible or audible label plus metadata. | Yes. | Platform enforcement under the 2025 Measures |
| US phone calls (FCC) | An AI voice is an artificial voice under the TCPA. | Same, and cloned voice scams are the target. | TCPA liability; prior express consent needed |

Almost every rule in this article turns on one idea: does the content pretend to be something real that it is not. The EU AI Act writes it down precisely. Article 3(60) defines a deep fake as “AI generated or manipulated image, audio or video content that resembles existing persons, objects, places, entities or events and would falsely appear to a person to be authentic or truthful”.
Read that slowly and a normal text to speech voiceover falls outside it. A stock AI narrator does not resemble an existing person. It reads your words, which you wrote and stand behind. Nobody listening is fooled into believing something false happened. It is closer to a font than to a forgery.
Three examples make the line clear.
The grey zone is a voice built to sound very close to a specific famous person without naming them. If a reasonable listener would think it is that person, treat it as imitation and label it. Beyond the labelling rules, imitating a real voice without permission raises separate personality and consumer protection issues in many countries, which is a good reason not to do it at all.
Four paragraphs matter to anyone publishing AI audio. Here is what each one says in plain words.
Paragraph 2 is for the companies that make AI tools. Providers of AI systems that generate synthetic audio, image, video or text must make sure the output is marked in a machine readable format and detectable as artificially generated or manipulated, using solutions that are effective, interoperable, robust and reliable as far as technically feasible. There are exceptions for tools that only perform standard editing or do not substantially alter the input. This is the watermark and metadata duty, and it sits with the tool maker, not with you.
Paragraph 4 is for you, the person publishing. The law calls you a deployer. If you use an AI system to generate or manipulate content that is a deep fake, you must disclose that the content has been artificially generated or manipulated. When the deep fake is part of an evidently artistic, creative, satirical, fictional or similar work, the duty is lighter: you disclose that generated content exists, in a way that does not spoil the work. A credit line or a note in the description is the usual answer.
The same paragraph adds a separate rule for AI generated text published to inform the public on matters of public interest. That text must be disclosed as AI generated unless it went through human review or editorial control and someone holds editorial responsibility. If you publish news style scripts that an AI wrote and nobody edited, that part applies too.
Paragraph 5 says when and how. The information has to be given in a clear and distinguishable way at the latest at the time of the first interaction or exposure, and it must meet accessibility requirements. A disclosure buried in a terms page that nobody reads does not meet that.
The AI Act applies generally from 2 August 2026 under Article 113, and Article 50 follows that date. In 2026 the EU passed a simplification package, the Digital Omnibus on AI, which entered into force on 27 July 2026. It moved the heavy high risk rules to 2 December 2027 and, for AI built into regulated products, to 2 August 2028. It did not move the transparency rules. The only change for them is a short window for the machine readable marking in paragraph 2: AI systems that were already on the market before 2 August 2026 must comply by 2 December 2026. Everything else in Article 50 has applied since 2 August 2026.
Article 2(1), point c extends the rules to providers and deployers based outside the EU where the output produced by the AI system is used in the Union. A channel run from the United States with a large European audience is in scope for the videos those viewers watch. Article 2(10) excludes people using AI in a purely personal, non professional activity, so a voice note for your family is not the target.
YouTube asks creators to disclose content that is meaningfully altered or synthetically generated when it seems realistic. Its examples of what needs disclosure are content that makes a real person appear to say or do something they did not, altered footage of real events and places, and realistic scenes that did not happen. Its examples of what does not need disclosure include cloning one’s own voice to create voice overs or dubs, production help such as scripts, titles and thumbnails, and caption creation. Unrealistic content, such as animation, needs nothing.
Two lines on that page matter most to creators. Disclosing AI content won’t limit a video’s audience or impact its eligibility to earn money. And creators who consistently choose not to disclose may get a label applied manually, or face penalties including removal of content or suspension from the YouTube Partner Program.
TikTok has required creators to label realistic AI generated content since 2023 and applies its own label to content made with its AI effects. Since 9 May 2024 it also reads Content Credentials, the C2PA metadata that some AI tools attach, and labels those uploads automatically. If a clip sounds or looks like something real that is not, turn on the AI generated content label when you post.
Meta’s wording is the broadest and the one most creators miss. Since February 2024 it has required people to use its disclosure tool when they post organic content with a photorealistic video or realistic sounding audio that was digitally created or altered, and it says it may apply penalties if they do not. It can also add a more prominent label when content carries a high risk of materially deceiving people on an important matter. A lifelike AI narrator is digitally created audio, so on Meta’s apps the careful move is to label it, even when YouTube would not require it.
For music, Spotify announced on 25 September 2025 that vocal impersonation is only allowed when the impersonated artist has authorized it, and that it is backing an industry standard for credits so artists can show where and how AI played a role in a track. In the twelve months before that announcement it said it had removed more than 75 million spammy tracks.
ACX, the route most independent authors use to reach Audible, is the strictest. Its audio submission requirements, dated 15 April 2026, say your audiobook must be narrated by a human unless otherwise authorized, and they list unauthorized text to speech, AI and automated recordings as not allowed. If you plan an AI narrated audiobook, check the rules of the specific store first. Our audiobook guide covers the options in detail.
China’s Measures for Labeling AI Generated Synthetic Content and a mandatory national standard took effect on 1 September 2025. They require explicit labels that people can see or hear, which for audio can be text, voice or rhythm cues, plus implicit labels in the file’s metadata. People publishing AI generated content on platforms must declare it and use the platform’s labelling tools.
There is no single US federal labelling law for AI voiceovers in videos. For calls there is a clear rule. On 8 February 2024 the FCC ruled unanimously that AI generated voices are artificial under the Telephone Consumer Protection Act, so calls that use them follow the rules for artificial or prerecorded voice calls, which means prior express consent. Several states have their own laws on voice likeness and election deepfakes, so check your state before using any voice that resembles a real person.
Use the platform’s own switch first.YouTube’s altered or synthetic content setting, TikTok’s AI generated content label and Meta’s AI info tool all put a standard notice where viewers expect it. They also tell the platform you disclosed, which is what protects you if its detection flags the video later.
Add one plain sentence people will see early.The EU rule asks for disclosure at the first exposure. A line at the top of the description, such as “The narration in this video is an AI voice,” or “This clip uses an AI recreation of a real person’s voice,” does more than a hashtag at the end.
Say it out loud when the audio travels alone. Podcasts, audio ads and voice notes get shared without their description. A short spoken line at the start covers you wherever the file ends up.
Keep it proportionate for creative work. For satire and fiction the EU rule only asks you to disclose that generated content exists without spoiling the work. End credits or a card in the video are enough.
No real person imitated, nothing falsely real. Not a deep fake, and not on YouTube’s list. Label it on Meta’s apps anyway.
YouTube names cloning your own voice for voiceovers or dubs as needing no disclosure.
Cartoons, obvious robots and fantasy creatures are not realistic, so the realism based rules do not bite.
AI used for your script outline, title, thumbnail or captions needs no disclosure on YouTube.
A voice message for friends is outside the AI Act under Article 2(10).
Having a page read aloud to you is personal use. Publishing that audio as your own content brings the rules back.
The machine readable marking in Article 50(2) is the provider’s job. In practice that means metadata and watermarks inside the audio file that detection systems can read, such as the Content Credentials standard TikTok already uses to label uploads automatically. Tools that were on the market before 2 August 2026 have until 2 December 2026 to add it. New tools must ship with it.
Two practical consequences for creators. First, a file downloaded from a compliant tool may carry a hidden marker that platforms read, so a label can appear even if you forgot yours. Second, stripping that marker out does not remove your own duty to disclose a deep fake. The visible disclosure in Article 50(4) is yours either way.
Takes a minute per video. Answer yes to any of the first three and you label it.
If yes, it is a deep fake under EU law and every platform wants a label. If you do not have that person’s permission, reconsider publishing it at all.
A realistic scene that never happened, or edited footage of a real event, needs a label on YouTube and TikTok whatever voice you used.
Meta asks for a label on realistic sounding audio that was digitally created. A lifelike AI narrator counts. Use the AI info tool.
Then the AI Act applies to you even if you live elsewhere, and a deep fake needs a clear disclosure at first exposure.
Audiobooks through ACX must be human narrated unless authorized. Check the store’s own rules before you record a single chapter.
An AI narrator reading your own script is not a deep fake, and on YouTube and under EU law it needs no label. Meta is the exception: it asks for a label on any realistic sounding audio that was digitally created, so label it on Facebook, Instagram and Threads.
The moment a voice imitates a real person, or the video fakes something real, label it everywhere, clearly and early. Since 2 August 2026 that is the law in the EU, with fines up to 15 million euros or 3% of turnover, and it has long been the rule on the major platforms. A label costs you nothing: YouTube says it does not affect reach or earnings.
FreeTTS has no voice cloning. You pick one of its ready made synthetic narrators, paste your script, and you are never imitating a real person by accident.
Under the EU AI Act, whose transparency rules apply from 2 August 2026, an AI voiceover must be disclosed when it is a deep fake, meaning it resembles a real person or thing and would falsely appear authentic. A stock AI narrator reading the creator’s own script usually is not, while platforms such as Meta ask for a label on any realistic sounding AI audio.
