Can You Use an AI Voice on YouTube, Udemy, Audible, Spotify, Steam and TikTok?

Mostly yes. YouTube, Udemy, Spotify, Apple Podcasts, Steam and the big ad platforms all allow AI voices. Several ask you to label them, and one, ACX/Audible, still refuses AI narration you make yourself. The rules changed a lot in 2025 and 2026, so much of the advice online is out of date.

We checked every rule below against each platform's own pages on 24 October 2026. Each row links to a guide with the details and sources.

The short version

What's the same everywhere?

Three things hold on every platform:

1. The content is judged, not the voice. YouTube won't pay for mass-produced videos and Udemy won't accept courses that are entirely AI-generated, whoever or whatever reads them. Original work with an AI voice is fine.
2. Real people need permission. Making a real, identifiable person appear to say something they didn't is where every platform draws a hard line, and where the law is moving fastest. Clone only your own voice, or a voice whose owner has agreed.
3. Quality decides the rest. Udemy's reviewers, Google Play Books and listeners all reject robotic, mispronounced audio. Direct the voice line by line and fix names once in a pronunciation list.

And the law?

Since 2 August 2026 the EU's AI Act asks anyone who publishes a deepfake, including cloned audio that makes a real person appear to speak, to say it's AI-generated. A licensed stock AI voice reading your own script isn't a deepfake. In the US, Tennessee's ELVIS Act protects a person's voice, including simulations of it, and AI voices in phone calls need the called person's prior consent. Our guide to commercial use covers this in plain words.

Can I use Leelo's voices on these platforms?

Yes. Audio you make on a paid plan can be used commercially, in videos, podcasts, audiobooks, courses, ads, apps and games, even after your plan ends. Audio made on the free plan is for personal use. Labelling the content on each platform is up to you, using the settings described in each guide.

Platforms change their rules often. We check these pages regularly; the date at the top says when we last did.
