Core Facts
Timeline (last 90 days)
Mistral claims that Voxtral 3 leads Whisper and ElevenLabs in accuracy, but this conclusion comes only from the company's own charts and has no independent benchmark support yet.
Voxtral 3 pushes the cost of full real-time voice conversation down to 4 cents per minute.
Voxtral 3 provides a unified voice stack comprising three speech recognition models, one speech generation model, and a real-time voice agent toolkit.
In early independent developer tests, Voxtral 3's full voice round-trip response was reported to be under one second.
Voxtral 3's real-time transcription model uses both acoustic signals and semantic information to determine when a caller has finished speaking, thereby reducing awkward pauses and accidental interruptions.
Voxtral 3 supports more than 50 languages and allows enterprises to write custom terminology directly into the transcription prompt.
Voxtral 3's batch transcription pricing starts at 0.35 cents per minute.
Voxtral 3's full real-time agent (paired with Mistral Small 4) is priced at 4 cents per minute; switching to a larger reasoning model doubles the cost to 8 cents per minute.
Enterprises can run the entire Voxtral 3 stack on European servers or self-host it on private hardware.
Developers report that Voxtral 3 still requires careful manual audio tuning in noisy environments, and its robustness has not yet reached plug-and-play level.
