How to generate an AI voiceover

Three steps, no account, and your script never leaves your device.

Step 1

Write your script

Paste the text you want narrated. There is no character limit, so a full demo narration works fine.

Step 2

Pick a voice

Choose one of the nine French and English voices and set the speaking speed. The first use downloads that voice to your browser.

Step 3

Generate and download

Listen to the result, then download the WAV file. No watermark and no attribution required.

Why this voice generator is different

Every other free AI voice tool runs on a server, which is why they all ask for an account and cap how much you can generate. This one runs on your machine.

Your text never leaves your browser

The speech model runs on your device. Your script is not uploaded, not logged, and never stored on our side.

No account, ever

No email, no credit card, no trial to cancel. Open the page, type your script, and generate.

No character limit

Generate a 20-word hook or a 20-minute narration. There is no monthly quota, because there is no server bill behind it.

Works offline

Once a voice has been downloaded it stays in your browser, so you can keep generating voiceovers with no connection.

French and English voices

Four French voices plus American and British English, male and female, built on the open-source Piper speech models.

Free for commercial use

The Piper voices ship under an MIT licence. Use the audio in client work, ads, or a paid product, with no attribution.

What people use it for

A voiceover you can regenerate as many times as you need, which matters most when the script keeps changing.

Product demo videos

Narrate a SaaS walkthrough without recording your own voice, or generate a draft voiceover to time your screen recording before the real take.

Tutorials and how-tos

Give step-by-step guides a consistent narrator, and fix a wording mistake by regenerating one sentence instead of re-recording the whole video.

Internal training videos

Produce onboarding and process videos in-house, and update them whenever the process changes without booking a voice actor again.

Social media and shorts

Add narration to reels, shorts, and ads. Generate several versions of a hook and keep the one that performs best.

Frequently asked questions

• Is this AI voice generator really free?
  Yes, and there is no paid tier for it. The speech model runs on your own device instead of our servers, so generating a voiceover costs us nothing and there is nothing to meter. There is no watermark on the audio and no trial to cancel.

• Do I need to create an account?
  No. There is no sign-up, no email, and no credit card. Type your script and generate, the same way you would use a calculator.

• Which AI should I use for a voiceover?
  It depends on what you are optimising for. If you want the most expressive, human-sounding result and you accept an account plus a monthly quota, ElevenLabs is the reference. If you want something free, unlimited, and private, an on-device model like the Piper voices used here is the better trade: slightly flatter delivery, but no limits and no upload.

• How do you generate a voice with AI?
  Write or paste your script, choose a voice, and click generate. The first time you use a voice, its model is downloaded to your browser, which takes a moment. After that, generation starts instantly and works even without a connection.

• What is the best free AI voice generator?
  Most free tools are free trials in disguise: a few thousand characters a month behind an account. If your definition of free is unlimited and without sign-up, an in-browser generator like this one is the honest option. If you need dozens of voices and emotional range for a single short project, a free tier from a large platform may suit you better.

• Is there a character limit?
  No. Long scripts are automatically split sentence by sentence and stitched back together, so a full tutorial narration is fine. Very long scripts simply take longer to generate.

• Can I use the audio commercially?
  Yes. The Piper voice models are published under an MIT licence, so you can use the generated audio in client work, advertising, or a paid product without attribution.

• Why is the first generation slower?
  Each voice is a model of roughly 63 MB that has to be downloaded to your browser once, and the very first run also fetches the speech engine itself. Both are then cached, so every later generation with that voice starts immediately. Switching to a different voice downloads that one too.

• Is my text sent to a server?
  No. Synthesis happens entirely in your browser and your script is never transmitted. The only network requests are the one-time download of the voice model and the speech engine files.

• What audio format do I get?
  A WAV file, which every video editor accepts. If you specifically need an MP3, any converter will do it in a second, and the WAV keeps full quality in the meantime.

• Which browsers are supported?
  Recent versions of Chrome, Edge, Firefox, and Safari on desktop. The generator needs WebAssembly and browser storage for the voice model. On mobile it works, but the model download and generation are noticeably slower.

• How does it compare to ElevenLabs or Canva?
  Those tools have thousands of voices and more expressive delivery, and we are not pretending otherwise. What they do not have is unlimited generation with no account and no upload of your script. Pick this one for volume, privacy, and drafts, and pick them for a single hero voiceover where expressiveness matters most.
