Key distinctions behind the tool.

Which voices are available?

Whatever speech voices your browser and operating system provide. The Voice list fills when the engine loads.

Can I change speaking speed?

Yes. Rate runs from about 0.5× to 2×.

Does it work offline?

If the page is already loaded and the browser has local voices, playback can work offline. Some voices need a network.

Is my text uploaded?

No. Speech synthesis runs in the browser.

Why is Speak silent?

Check device volume, unmute the tab, and confirm speech synthesis is allowed. Try Stop then Speak again.
