Voxtral 3
Voxtral 3 combines multilingual speech transcription, expressive text-to-speech, and a real-time voice agent SDK for phone and web conversations. It helps teams build assistants and workflows that can understand spoken requests, use connected tools, and respond naturally.
Overview
Voxtral 3 is Mistral’s family of speech-to-text and text-to-speech models together with a voice agent SDK. It is designed for real-time, multi-step conversations in which an agent listens, interprets requests, uses connected tools, and responds with speech.
The product supports transcription in 50 languages, expressive speech generation in more than 35 languages and 50+ dialects, and deployment through Mistral’s EU-hosted API or on an organization’s own infrastructure. Its intended applications include contact-center and service-desk agents, virtual assistants, and hands-free copilots.
Core capabilities
Diarization and contextual recognition
The transcription models identify which speaker said what, detect when a speaker has finished, and accept keyphrases or free-form context to improve recognition of domain-specific terms without fine-tuning.
Expressive text-to-speech
Voxtral Mini TTS 3 generates speech in more than 35 languages and 50+ dialects, adapting emotion, pace, and emphasis to conversational context.
Real-time voice agent orchestration
The voice agent SDK links audio input, model reasoning, tool calls, and spoken output in a real-time streaming pipeline for live interactions.
Tool-enabled workflows
Agents can retrieve information, interact with business systems, and carry out multi-step actions through connected tools during phone or web conversations.
Professional voice adaptation
Pro Voice adaptation can reproduce a speaker’s distinctive character, emotional range, and speaking style across languages using 30 minutes of audio, according to the product page.
Use cases
Contact centers and service desks
A live service agent can transcribe a caller, distinguish speakers, detect turn completion, retrieve account or case information, and complete multi-step actions through connected business tools.
Conversational virtual assistants
Organizations can build assistants that handle spoken requests, reason over context, and respond with speech that varies its pace, emphasis, and emotion during the exchange.
Hands-free copilots
Voice interfaces can let users operate workflows while driving, moving through a facility, or otherwise keeping their hands and eyes occupied, with tool calls handling connected tasks.
Domain-specific meeting and call capture
Teams can use multilingual transcription with context biasing to capture conversations containing technical, medical, operational, or other specialized terminology without fine-tuning the model.
