Where do the voices come from?

They are the speech voices already installed on your device and exposed by your browser. The available list varies by operating system and browser.

Is my text sent to a server?

No. This tool uses the browser's built-in Web Speech Synthesis API, so your text never leaves your device.

Why do I see different voices on another computer?

Voices are provided by the operating system, so the selection differs between Windows, macOS, Linux, Android and iOS.

What do the rate and pitch sliders do?

Rate controls how fast the voice speaks and pitch controls how high or low it sounds. A rate of 1 and pitch of 1 are the natural defaults for the chosen voice.

Can I download the audio as a file?

No. The Web Speech API plays speech live through your speakers but does not expose a downloadable audio file, so there is nothing to save.

Does it work offline?

Once the page is loaded, speech is produced by your device's built-in voices, so it works without an internet connection on most systems.

My browser shows no voices — why?

Some browsers load voices asynchronously or require a system speech engine. Try reloading the page, or use a Chromium-based or Safari browser where system voices are reliably available.

Text to Speech — Gera Tools

Text to speech, right in your browser

This tool reads any text aloud using the voices already installed on your device — no account, no upload, no audio service. It is handy for proofreading by ear, accessibility, language practice, or simply listening to an article or note hands-free.

How it works

The tool uses the browser’s built-in Web Speech Synthesis API. When the page loads it asks the browser for the list of available voices, which come from your operating system, and selects the default. When you press Speak it creates a speech utterance from your text, applies your chosen voice, rate and pitch, and sends it to the speech engine, which plays it through your speakers. Stop cancels any in-progress speech immediately.

rate:  how fast the voice speaks (1 = natural)
pitch: how high or low it sounds (1 = natural)
voice: a system voice; the list depends on your OS and browser

Example

Paste “The meeting is at three o’clock.”, pick an English voice, set the rate to about 0.9 for a slightly slower delivery, and press Speak — the sentence is read aloud instantly. Lowering the pitch deepens the voice; raising the rate speeds it up for skimming long passages.

Because everything runs through your device’s own speech engine, no text is uploaded and it works offline on most systems.
