Overview

Product summary

Review the store description, core capabilities, and common use cases.

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.

love the idea behind this, but for some reason my voices have trouble reading a paragraph like this: "If you tell me which ending you got (and which parts are confusing: Old Monkey, headband, stone, Erlang, etc.), I can break down those specific scenes beat‑by‑beat."

This extension offers the best free text-to-speech voices I've found. The quality of these voices is on par with paid options like Speechify or Eleven Labs, and they are built upon open-source models readily accessible through platforms like Hugging Face and GitHub. It's my observation that high-quality text-to-speech voices often emerge from companies that also operate voice assistants. This is because these companies continuously gather and utilize vast amounts of voice data to refine and improve their models. This data-driven approach, in my opinion, is a key factor, and it might explain why Apple seems to be struggling with Siri; they haven't been as actively collecting and leveraging user data for AI development over the past decade in the same way.
