Free AI Text to Speech with Meta MMS-TTS - English TTS in Your Browser

What is MMS-TTS and how does it work?

MMS-TTS (Massively Multilingual Speech) is a text-to-speech model developed by Meta using the VITS architecture. This tool runs the English variant of MMS-TTS entirely in your browser via Transformers.js - your text is never sent to any server. The model is downloaded once from Hugging Face and cached locally for instant reuse.

How does MMS-TTS compare to KittenTTS?

While the KittenTTS models offer multiple voices and speed control, MMS-TTS provides a single English voice with a different tonal character. MMS-TTS uses Meta's VITS architecture, which produces clean, intelligible speech well-suited for straightforward narration. If you need voice variety or speed adjustment, KittenTTS Mini or Nano are better choices.

Can I download the generated audio?

Yes. After generating speech, you can play it directly in the browser and download it as a WAV file. MMS-TTS outputs 16kHz mono audio, which works well for voiceovers, e-learning content, and accessibility applications.

Is MMS-TTS free to use without limits?

Completely free with no sign-up required. The model runs locally in your browser using WebAssembly, so there are no API costs, no usage limits, and no account needed. Your device's processing power is the only limiting factor.

Is my text data private?

Yes. All inference happens locally in your browser. Your text is never uploaded to any server. The model weights are downloaded once from Hugging Face and stored in your browser cache. This makes the tool safe for sensitive or confidential content.

What browsers support MMS-TTS?

MMS-TTS works in any modern browser with WebAssembly support, including Chrome, Edge, Firefox, and Safari. For the best performance, use an up-to-date Chromium-based browser.

Free English text-to-speech for content creation

This tool is useful for generating voiceovers, creating audio versions of written content, testing how scripts sound when spoken, or producing accessibility audio for visually impaired users. Since there are no usage limits, you can process as much text as your device can handle.
