Mistral AI Launches Voxtral 3 Voice Agent Model Family
Mistral AI has launched Voxtral 3, a model family for real-time voice agents. It combines transcription, speech synthesis, and a LiveKit-based SDK for listening, thinking, tool use, and speaking in one streaming pipeline.
What Voxtral 3 includes
Mistral AI has launched Voxtral 3, a new family of language models built for real-time voice agents. The release brings together a speech-to-text model, Voxtral Small Transcribe 3, a text-to-speech model, Voxtral Mini TTS 3, and a voice agent SDK based on LiveKit. Mistral presents the components as a single streaming pipeline that can listen, think, use tools, and speak during the same live conversation.
Transcription covers more than 50 languages. Text-to-speech output supports over 35 languages and 50 dialects, with emotional adaptation. During a call, agents can connect to external systems for tasks such as booking appointments or checking invoices.
Deployment and data control
Mistral says Voxtral 3 can run on a customer's own infrastructure or through EU-hosted APIs, a setup aimed at keeping data under the deployer's control. Pricing starts at $0.0035 per minute for transcription. The company directs readers to its documentation for more details.
