Why do the available voices differ between devices?

Because they come from your operating system, not from us. macOS, Windows, Android and iOS each ship a different set, and a voice you hear on one machine may not exist on another. Some browsers also load additional voices only after the page has been open a moment.

Can I download the audio as a file?

Not from the browser's speech API — it plays to your speakers and exposes no recording hook. Saving the output requires a server-side speech service, which would mean sending your text somewhere.

Is my text sent to a speech service?

No. SpeechSynthesis uses the voices installed on your own device, so the text is spoken locally. Note that a few platforms use a cloud voice for certain high-quality options — if that matters to you, pick a voice your OS lists as offline.

Text to Speech

Paste text and have it read aloud using the voices already installed on your device, with control over voice, speed and pitch. It uses the browser's built-in SpeechSynthesis API, so the audio is generated locally and your text is never sent to a speech service.
