Voxtral TTS: AI Voice Generation & Cloning
Learn Voxtral TTS — Mistral's open-source voice AI that clones any voice from 3 seconds. API setup, voice cloning, 9 languages, self-hosting, and honest limits.
ElevenLabs charges $22/month for voice cloning. Voxtral does it from 3 seconds of audio at $0.016 per thousand characters — and the model weights are free to download.
Mistral released Voxtral TTS on March 26, 2026, and it immediately outperformed ElevenLabs Flash v2.5 in human evaluations. Not by a small margin — 62.8% of listeners preferred Voxtral’s voice quality. It supports 9 languages, runs on a smartphone, and can clone any voice from a few seconds of recording.
But there are important gotchas that most tutorials skip. Voice cloning is API-only right now — the codec encoder isn’t in the open weights. The license is CC-BY-NC, meaning commercial self-hosting isn’t allowed. And while the 20 preset voices are excellent, the real power is in the API.
This course covers all of it — honestly. What Voxtral does well, what it can’t do yet, and how to use it for real projects.
What You’ll Learn
8 lessons take you from zero to a finished audio project. You’ll set up the API, clone your own voice, generate multilingual content, learn when to self-host vs use the API, and build something real — a podcast episode, audiobook chapter, or voiceover reel.
No coding experience required. If you can copy-paste a URL, you can use Voxtral.

Frequently Asked Questions
Is Voxtral TTS really free?
The open weights are free to download and self-host for non-commercial use (CC-BY-NC license). The API costs $0.016 per 1,000 characters — roughly 18x cheaper than ElevenLabs. Commercial use requires the API.
Can I clone my own voice?
Yes — with just 3 seconds of audio. Voice cloning currently works via the API. Self-hosted voice cloning is not yet available in the open weights release (the codec encoder is missing).
What languages does it support?
Nine languages: English, French, German, Spanish, Dutch, Portuguese, Italian, Hindi, and Arabic. Cross-lingual cloning also works — you can use a French voice to speak English.
Do I need a powerful computer?
For self-hosting: 16GB GPU VRAM minimum. For the API: any device with internet works. The course covers both paths.
