Do I need to label AI voiceover on YouTube Shorts?
Sometimes. YouTube requires a label when a synthetic voice makes a real person seem to say something, and lists AI music as an example. Own-voice clones do not.
It depends on whose voice it is and how real it sounds. YouTube's page says disclosure is needed when realistic content makes a real person appear to say something they did not, and it exempts cloning your own voice for voiceovers or dubs. It also lists AI-generated music as an example that needs disclosure. A generic narrator voice is not named on the page.
Everything about YouTube is from its disclosure help page, read 2026-09-29. The Sume side is from the avatar video and Music 1.0 docs.
Which voices and sounds does YouTube name?
Only the entries on the page are listed.
| Audio case | What the page says |
|---|---|
| A real person made to say something they did not | Disclosure needed for realistic content |
| AI-generated music | Listed as an example to disclose |
| Cloning your own voice for voiceovers or dubs | Not needed |
| Voice or audio repair | Not needed |
| A generic synthetic narrator | Not named on the page |
What about a voice that belongs to a generated person?
Sume's avatar talking video speaks a script you supply: each scene's voice takes type: "text" with a script or input_text, and type: "silence" for a non-speaking beat. The result is a realistic generated person talking, so the picture is what pushes it toward disclosure, in my reading. The page does not rule on this case.
Does AI music in a Short need the label?
YouTube lists AI-generated music as an example of content creators need to disclose, so a Short with a Music 1.0 track under it falls in that example. Music 1.0 is created with POST /v1/music-1.0/generate from a text prompt of up to 5000 characters.
How do I decide when the case is unclear?
Check whether a viewer could take the audio for a real person saying real words. If yes, disclose. If the voice is your own, the page exempts it. If you cannot tell, disclosing costs little: the page says the label shows in the player for photorealistic content and in the expanded description otherwise.
What if a Short mixes several cases?
Judge each track on its own and disclose if any one needs it. A Short with a fantastical picture, an own-voice voiceover and AI music still meets the music example, so the video gets the label. YouTube says the label appears in the player for photorealistic content and in the expanded description otherwise, so a mixed Short is not penalized by the label's placement.
- Own voice, real footage, no AI music: no disclosure from these parts.
- Generated person speaking a script: disclose, in my reading.
- AI music under any picture: disclose, since the page lists it.
