Description

Supertonic is a collection of high-quality AI-powered text-to-speech (TTS) voices developed by Supertone, Inc. These voices are synthesized in-browser, requiring no cloud subscriptions, and are entirely free to use. Once installed the voices will be added to the browser's list of available TTS voices, and usable by websites, apps, and by other browser extensions to synthesize text to audio. Please be patient while Chrome downloads and installs this extension, as it is quite large due to the AI model being included in the distribution package.
