Free AI Voiceover You Can Use on a Monetized Channel: What to Check
Most free text-to-speech plans exclude commercial use. What the licence terms mean for faceless channels, explainers and ads, and how to make a voiceover with open voices that run on your own computer.
Faceless YouTube channels, course videos, explainers and small-business ads all need a voice. The catch with most AI voice tools is not quality but the licence: free plans commonly exclude commercial use, and a monetized channel is commercial use.
What to check before you publish
- Commercial rights on the plan you used. For example, ElevenLabs' free plan doesn't include a commercial licence even with attribution; its paid plans do.
- Limits. Free tiers are often around 10 minutes of audio a month.
- Voice cloning rules if you use a cloned voice: only your own voice, or with written permission.
Open voices that run on your computer
Cuescribe's voiceover generator uses Kokoro, an open text-to-speech model released under the Apache 2.0 licence, which allows commercial use. It runs in your browser after a one-time download (about 90 MB), so there is no character limit and nothing to pay per word.
Make it sound natural
- Write for the ear: short sentences, one idea each.
- Use blank lines between paragraphs; they become longer pauses.
- Spell out unusual names the way they're said.
- Try two or three voices on the same paragraph before committing.
Captions included
The SRT you download is timed to the generated audio, so captions line up exactly. Put it under your video, or turn the voiceover into an audiogram.
