Mistral AI launches Voxtral 3, a multilingual voice‑agent SDK with real‑time speech‑to‑text and text‑to‑speech models

Mistral AI has released Voxtral 3, a new family of speech‑to‑text and text‑to‑speech models that support more than 50 languages and dialects. The Voxtral Small Transcribe 3 model delivers highly accurate multilingual transcription with diarization and end‑of‑turn detection, while Voxtral Mini TTS 3 offers expressive, emotion‑adaptive speech synthesis. The accompanying SDK stitches listening, reasoning, tool‑calling, and speaking into a single real‑time streaming pipeline, enabling contact‑center agents, virtual assistants, and hands‑free copilots to perform multi‑step tasks across integrated systems. Voxtral 3 is available via Mistral’s EU‑hosted API or for sovereign self‑deployment, giving organizations control over data sovereignty and low‑latency interactions.
