Free text to speech for commercial use: what is actually allowed
Free and free for commercial use are not the same thing. A text-to-speech tool can cost nothing and still limit what you may do with its voices, and a voice can sound perfect and still belong to someone who never agreed to your ad.
This guide explains, in plain words, what has to be covered before you put a synthetic voice into an ad, a course, a game or a monetized channel, and which SuperClonica voices you can use commercially for free.
Four things free for commercial use must cover
A tool can be free and still not cover commercial use of its voices; check all four.
- The software license of the engine.
- The license of the speech model.
- The voice itself: whose voice it is and whether that person agreed.
- The rules of the platform or store where the audio goes.
Hear the voices free
On the page of any voice, type a line of 30 to 100 characters, choose the language and press Voice it. In a few seconds you hear it, with no account; the ten stock voices come with the free engine.
What you may use commercially with SuperClonica
Keep the speaker’s written consent with your project files: it is your proof if anyone asks.
- The SuperClonica engine and its Docker image are released under the Apache License 2.0.
- The Supertonic 3 model is under OpenRAIL-M, a royalty-free license that allows commercial use within its list of prohibited uses.
- The ten stock voices of the model, M1 to M5 and F1 to F5, are free and come under the model license.
- A voice trained in the SuperClonica studio from a recording of a speaker who agreed to commercial use.
What to avoid in commercial work
Character, parody and celebrity-inspired voices in the catalog are fan-made; they are not licensed by the rights holders and are meant for fan and parody projects. A purchased catalog voice is for your own projects under the SuperClonica terms, and the terms do not grant extra commercial rights, so for a commercial project use a stock voice or a trained voice, or ask the voice’s author. Follow the prohibited uses of OpenRAIL-M: no impersonation without consent, no deception, no harassment.
Say it is synthetic where it matters
Many platforms and stores ask creators to label realistic synthetic audio, and some have their own rules for AI narration. Say that a voice is machine-generated where listeners would care, and never present it as a real person.
