Text to Speech Commercial Use: What Each Provider's License Allows

Yes, text to speech commercial use is allowed in most cases, but the answer depends on the provider, the plan you are on and the voice you pick. Paid cloud APIs generally let you keep and use the audio you generate, while some free plans do not include commercial rights at all. Before you put a synthetic voice in an ad, a course, a podcast or your website audio, check who owns the output, whether your plan includes a commercial license, and what the provider says about disclosure and voice cloning.

This is not legal advice. It summarizes the official terms and help pages we read in September 2026. Terms change, so read the current version for your plan, and talk to a lawyer when a lot of money or a real person's voice is involved.

The questions that decide text to speech commercial use

1. Who owns the output?

Look for a sentence saying the generated audio belongs to you, or that the provider assigns its rights in it to you. Silence is not a ban, but it gives you less certainty.

2. Does your plan include a commercial license?

Some providers treat free and paid output the same way. Others, such as ElevenLabs, say the free plan cannot be used for any commercial purpose. Beta or preview features can also carry their own restrictions.

3. Do you have to credit the provider?

Attribution rules usually apply to free tiers, and crediting a provider does not make a non-commercial license commercial.

4. Can you clone or imitate a real person's voice?

The ElevenLabs, OpenAI and AtlasVoice terms we read prohibit impersonation, and Google and Microsoft require the speaker's recorded or written consent before a custom voice is created. Some custom voice features are only available after an approval process.

5. Must you tell listeners the voice is AI?

Some providers, and some laws, require you to disclose that the voice is synthetic. A short line such as "This article is read by an AI voice" near your player is an easy habit.

6. Can you store, reuse and redistribute the files?

Websites, videos and podcasts save an MP3 once and play it many times. Check that the terms do not limit caching, and never resell API access or keys.

7. Can the audio be used to train AI models?

Several providers forbid using their output to build a competing model. Also check whether the provider may use your text to improve its own service.

8. Do you have the rights to the text?

Providers make you responsible for the input text. Reading someone else's article or book aloud still needs their permission.

Browser voices: a special case

Many website players, including the free AtlasVoice plugin by default, use the voices built into the visitor's browser or operating system. The browser produces the speech when the listener presses play (some browsers use online voices for this), so you are not creating or hosting an audio file. The voice itself is licensed by the operating system or browser vendor, not by the plugin. If you record those voices into an MP3 to publish elsewhere, such as a YouTube video, check that vendor's license first.

What each provider's terms say (as of September 2026)

These summaries come only from official pages, linked in each entry. Where a page does not address commercial use directly, we say so. AtlasVoice is our own product.

Google Cloud Text-to-Speech

The Google Cloud Terms of Service (opens in a new tab) say you retain all intellectual property rights in your Customer Data, which the terms define to include data you derive from what you send through the services. We did not find a page that addresses commercial use of Text-to-Speech audio directly, so treat it as not stated explicitly and check the service terms. The Service Specific Terms (opens in a new tab) (last modified September 24, 2026) add restrictions for AI/ML services, the group Text-to-Speech is listed under: you may not use a service or its output to develop a similar or competing product, or to create or improve models similar to Google's. The same document has extra rules for "Generative AI Services", so check whether the voice model you choose falls under them. Chirp 3: Instant Custom Voice (opens in a new tab) requires a recorded consent statement from the voice owner.

Is Google text to speech free for commercial use? The pricing page (opens in a new tab) lists a free monthly character allowance for several voice types, and billing must be enabled. We found no separate usage rules for the free allowance.

Microsoft Azure AI Speech

The text to speech transparency note (opens in a new tab) says prebuilt neural voices may be used for use cases customers choose, consistent with the Azure Acceptable Use Policy and Microsoft's code of conduct, and that no registration or pre-approval is needed for those. It also states that Microsoft requires customers to disclose the synthetic nature of text to speech voices to their users. Custom neural voice and personal voice are Limited Access features restricted to approved use cases, and custom voices need explicit written permission from the voice talent. Output ownership is not stated on these pages; check the Microsoft terms for your subscription.

Amazon Polly

The Amazon Polly FAQs (opens in a new tab) say "your Polly output belongs to you" and that the service has "no restrictions on storing and reusing generated speech". The FAQ does not use the word "commercial". The AWS Service Terms (opens in a new tab) (last updated September 15, 2026) confirm that output from AI services is Your Content, and note that AWS may use content processed by Polly to improve its services unless you use the documented opt-out.

ElevenLabs: free vs paid

ElevenLabs ties rights to your plan. Its help page "Can I publish the content I generate on the platform?" (opens in a new tab) says the free plan "does not include a commercial license", and that free-plan content you publish must credit ElevenLabs by including "elevenlabs.io" or "11.ai" in the title. All paid plans include a commercial license, and content generated during a paid subscription can be used commercially indefinitely, but content made with Beta Services cannot be used commercially. The Prohibited Use Policy (opens in a new tab) (last updated August 17, 2026) bans replicating another person's voice without consent or legal right, or in a way meant to deceive people about whether the voice is AI. Our guide to ElevenLabs voices on WordPress (opens in a new tab) covers the setup side.

OpenAI

The OpenAI Services Agreement (opens in a new tab), which covers API customers, says the customer owns all Output, and it bars using Output to develop AI models that compete with OpenAI. The text to speech guide (opens in a new tab) states that OpenAI's usage policies require "a clear disclosure to end users that the TTS voice they are hearing is AI-generated and not a human voice." The usage policies (opens in a new tab) also prohibit using someone's voice without consent in ways that could confuse authenticity. More on the voices themselves is in our OpenAI text to speech guide (opens in a new tab).

AtlasVoice (our product)

The AtlasVoice Terms of Service (opens in a new tab) (last updated September 27, 2026) say you own the text you send and the audio you create, and you may use that audio "for any lawful purpose, including commercial use", as long as you follow the terms. The acceptable use rules forbid impersonating a real person, and presenting AI-generated speech as a human recording where the law requires you to say it is AI-generated. Some AtlasVoice voices are built on third-party voice models whose licenses require these restrictions to be passed on, so if you let others use your audio, the same rules go with it. We do not store your text, do not keep the audio beyond a few minutes, and do not use either to train AI. These terms cover the AtlasVoice voice service, which powers the free AtlasVoice TTS voice (100,000 characters a month, in the public beta of the free plugin's 2.4 release), and the AtlasVoice API (opens in a new tab).

One detail for WordPress users: if you use Google Cloud, ElevenLabs or OpenAI voices through AtlasVoice Pro, you connect your own account with that provider, so the provider bills you and its terms, above, decide what you may do with the audio.

Text to speech free commercial use: where the free options stand

If you need text to speech for commercial use without paying, the free tier you pick matters. Of the pages above, only ElevenLabs' free plan explicitly rules out commercial use. The Google Cloud pages we read do not give its monthly free allowance separate usage rights, and the AtlasVoice terms allow commercial use of the audio you create on any plan. Our comparison of free text to speech APIs (opens in a new tab) covers limits and setup for each.

A practical checklist before you publish

• Save a dated copy of the terms and the plan you used.

• Confirm your plan includes commercial use, and that you did not use a beta or preview feature that excludes it.

• Add any attribution your plan requires.

• Make sure you have the rights to the text being read.

• Use a cloned or custom voice only with the speaker's written consent, and never imitate a real person without it.

• Add a short "read by an AI voice" note wherever listeners might assume a human.

• Do not use the audio to train a model that competes with the provider.

• Recording browser voices for use elsewhere? Check the operating system or browser vendor's license first.

• Re-read the terms yearly; several pages above changed in 2026.

Your next step

For WordPress, start with the free plugin: browser voices need no account, and the AtlasVoice TTS voice gives you MP3s you own. Our guide shows how to add text to speech to WordPress posts (opens in a new tab). Developers can get a free key for the AtlasVoice API (opens in a new tab).
