We’re seeing builders from the community move fast with Supertonic, our lightweight, on-device text-to-speech model.
From browser extensions and demos to full-fledged apps, creators are already shipping with Supertonic in real-world products. 🚀

Read Aloud, PageEcho, VoiceChat … These are just a few of the projects we witnessed make waves with Supertonic.
Curious how each team is using this on-device TTS in practice? Let’s take a closer look at the article!

Read Aloud, trusted by more than 6 million users, has added Supertonic as a new voice option to its text-to-speech Chrome extension. 📢

The Read Aloud team praised Supertonic for its ability to deliver “amazing voices that can run on commodity devices,” and shared expectations for the voices’ adoption across the platform.

Try Supertonic on Read Aloud!

⚡ MS Edge: https://t.co/BFRda7kLFJ
⚡ TTS Tool: https://t.co/yhQfO1YFJw

As a platform widely used in schools, Read Aloud’s adoption of Supertonic is expected to lower the barrier to high-quality text-to-speech without specialized hardware, as Supertonic is designed to deliver strong voice quality directly on-device. 📚

We’re grateful for the trust and feedback, and we’ll continue focusing on making voice AI more accessible.

@RachdiSham64061 Hi, the current model may occasionally mispronounce certain inputs (e.g., pluralized acronyms or text that hasn’t been fully normalized). We’re actively working to improve overall TTS stability, with updates planned for an upcoming release. Thank you for reporting this issue!

[Supertone @Supertone_ai]

Now with a Python package, Supertonic fits into your workflow even better. 📂

Fresh updates:
➤ Supertonic is available as a pip-installable Python package for use in Python and CLI environments.
➤ Six new voice presets have been added, offering ten presets in total for exploring a broader range of vocal characteristics.
➤ The model checkpoint has been updated with ONNX-level optimizations that improve inference speed.

Voice embedding functionality is currently in preparation and will allow developers to generate speaker embeddings for their own applications.

In addition, Supertonic is provided as an open-weight model: the weights are publicly available, but the training code and data are not open source. We want to ensure this distinction is communicated clearly.

Hi Lomas. For this model, we currently provide English TTS. We’re planning to release additional supported languages such as Korean, Japanese, Spanish, and Portuguese in API form.

Also, thank you for the suggestion—it actually reminded me of a phrase my Georgian friend once taught me: “ეს არის სასიამოვნო”. (Still one of my fav thing to say randomly)

We don’t have concrete plans to support it yet, but we’ll continue working to make our tools more useful in the future! Thank you.

[Supertone @Supertone_ai]

@hibaby343 Currently, the model on Hugging face supports English TTS only, with four voices (2Female/2Male).

API support for Korean, Japanese, Spanish, and Portuguese is on the way!

Appreciate the interest, thank you!

[Supertone @Supertone_ai]

@opener_ai Spine-tingling work, Thanks for tagging us for the voice part!

[Supertone @Supertone_ai]

@RachdiSham64061 Thank you for sharing this suggestion — we’re still exploring various use cases, and your input is truly appreciated!

[Supertone @Supertone_ai]

@ryanator2000000 Thanks so much for trying the demo and letting us know! Could you tell us which Android device and browser you’re using so we can look into it for future improvements?

[Supertone @Supertone_ai]

@RodFdw @xenovacom So far, yes! However, we are thinking of offering more language options in the future, maybe in API format

[Xenova @xenovacom]

Massive kudos to the @Supertone_ai team for this fantastic model release. I honestly can't believe something like this is finally possible! 🤩
