Processed entirely on your device

Your text script never leaves your browser tab.

Thryve Speak turns English text into clear, natural WAV audio directly in your browser. Supertonic runs locally on your device, so your script is never uploaded or stored by Thryve.

Frequently asked questions

Does Thryve Speak upload my text?

No. Speech generation runs locally in your browser. The synthesis path downloads the Supertonic model, voice data, and browser runtime assets only when they are not already cached.

Which languages are supported?

Thryve Speak currently generates English speech. The underlying Supertonic model supports additional languages, but the Speak interface currently exposes English mode only.

What audio format can I download?

Thryve Speak downloads generated speech as a WAV file.

Is there a free tier?

You can download 10 WAV files per month free. Thryve Speak Pro is a one-time $5 purchase with unlimited downloads, and Thryve OS Pro also includes Speak.
