Piper Text-to-Speech Voices

Piper is a collection of high-quality, open-source text-to-speech (TTS) voices developed by the Piper Project, powered by machine learning technology. These voices are synthesized in-browser, requiring no cloud subscriptions, and are entirely free to use.

This extension lets you install Piper voices to your computer, then adds these voices to the browser's list of available TTS voices, which can then be used by websites, apps, and by other browser extensions to synthesize text to audio.

For example, after installing your favorite voices. You can use this tool to test them out:
