What is the text to speech tool?

A reader that speaks any text aloud using your device's own built-in voices, with adjustable rate, pitch and volume. It plays the audio live through your speakers and works fully offline — nothing you type leaves your browser.

How to use Text to speech

  1. Enter your text — Type or paste the text you want read aloud into the box.
  2. Pick a voice — Choose from the voices your operating system provides in the Voice dropdown. The available voices depend on your device.
  3. Adjust the delivery — Use the Rate, Pitch and Volume sliders to speed up, slow down or change how the voice sounds.
  4. Play and control — Press Play to hear it, then use Pause, Resume and Stop as needed.

Frequently asked questions

Where do the voices come from?

They're the text-to-speech voices already installed on your device through your operating system. The tool simply uses them, so the list varies from one computer or phone to another.

Can I download the audio as a file?

No. This plays audio live through your speakers using your device's built-in voices — there's no audio file to save or export.

Does it work offline?

Yes. It's 100% offline and nothing you type is uploaded, since it relies on the voices already on your device.

Why are no voices showing?

If your device has no speech voices installed, the controls may stay disabled. Add at least one text-to-speech voice through your operating system's settings and reload.

Can I change the speed and pitch?

Yes. The Rate slider controls speaking speed, Pitch changes how high or low the voice sounds, and Volume sets the loudness.
