Introducing Voxtral 3: state-of-the-art Transcribe and Speech models powering Mistral’s new voice agents API. 🧵

Voxtral Small Transcribe 3 is state-of-the-art in multilingual transcription, diarization and context-biasing.

It detects when someone has finished speaking so agents can respond without delay.

Voxtral Mini TTS 3 achieves state-of-the-art expressiveness in 35+ languages and 50+ dialects.

Implicit instruction-following reads emotion, pace, and emphasis from the conversation.

With explicit instruction-following, tags like [emotion=sad][pace=slow] set them line by line.

With Pro Voice, we’re also rolling out professional voice adaptation.

Record up to 30 minutes of audio to replicate your voice with extreme fidelity across every supported language.

Voxtral 3 also introduces a voice agent SDK, built on LiveKit.

Transcribe listens, a reasoning model thinks and calls tools, and Speech replies, streamed as one pipeline for natural, intelligent conversation.
