Voxtral 3
Mistral’s speech-model family for multilingual transcription, expressive TTS, and real-time voice agents with tool calling.
Updated 2026-10-21
No free tier is documented for Voxtral 3.
Listed pricing: Transcribe from $0.0035/min; TTS $13/1M chars; voice agents $0.04–0.08/min.
Overview
Voxtral 3 is Mistral AI’s speech stack: transcription and text-to-speech models plus a LiveKit-based voice agent SDK for streaming, multilingual conversations with tool calling. It targets builders who need production voice I/O—meeting capture, IVR-style agents, or branded spoken interfaces—rather than a consumer chat app.
The launch pitch is end-to-end coverage in one vendor lane: strong multilingual ASR with diarization, expressive TTS and cloning for consistent speaker identity, and a real-time agent pipeline instead of bolting separate STT, LLM, and TTS vendors together. That matters for latency-sensitive agents where glue code and vendor sprawl usually dominate cost and failure modes.
It’s still an API/SDK product, not a polished meeting-notes SaaS like Otter or Fireflies. Teams that want zero infra will use Mistral’s hosted rates; teams that need control can self-deploy. Closest rivals are specialist voice-agent platforms (Vapi, Retell, Bland) and other speech APIs—Voxtral’s edge is Mistral’s unified model + agent surface, not a turnkey meeting product.

Worth it if
The strengths recorded against this entry.
- Unified STT, TTS, and streaming voice-agent SDK from one vendor
- Multilingual transcription with diarization positioned for production call and meeting audio
- Expressive TTS plus voice cloning for consistent branded speakers
- Tool calling in live voice sessions, not just post-hoc transcript chat
Not worth it if
Any one of these blocks your use case.
- API/SDK focused—no full meeting-notes product UI for non-builders
- Voice-agent minute rates add up fast versus batch transcription alone
- Self-deploy path shifts ops burden (latency, scaling, compliance) onto your team
- Category rivals (Vapi, Retell, Bland) may ship more turnkey telephony connectors
Key features
Multilingual ASR
Transcription models aimed at multilingual speech with diarization, suited to meetings, call centers, and mixed-language content without a separate speaker pipeline.
Expressive TTS
Text-to-speech tuned for natural, expressive delivery, including voice cloning so agents and products can keep a consistent speaker identity.
Voice agent SDK
LiveKit-based streaming voice agents with tool calling, so conversations can invoke functions while staying in real-time audio rather than turn-based chat.
API or self-host
Available through Mistral’s API pricing or self-deploy paths, giving teams a choice between managed minutes and their own infra.
