What we know about Voxtral TTS

Voxtral TTS is a text-to-speech apis platform: open-weights-friendly voice cloning TTS from a frontier AI lab. This profile tracks what we have verified about Voxtral TTS, each fact linked to a primary source and dated.

Voxtral TTS does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Voxtral TTS quote, it is the fastest way for us to close that gap.

On capabilities, Voxtral TTS covers streaming audio output, instant voice cloning, and self-host / on-prem option, and does not offer realtime websocket api, professional voice cloning, and ssml support. Each of those is verified against Voxtral TTS's own docs or dashboard, not marketing copy.

In total we track 16 verified facts for Voxtral TTS today, and add coverage as the ingestion pass revisits it. Where a number is a vendor claim rather than our own measurement, it is labeled as such on the Voxtral TTS fact sheet below, and each row links the primary source it came from so you can check our work.

Whether Voxtral TTS is the right call depends on your use case more than any single spec, which is why the head-to-head verdicts below score it per scenario rather than crowning one overall winner. Use the fact sheet for the raw numbers, and the matchups for how Voxtral TTS actually fares against the platforms buyers most often weigh it against.
