Mistral releases Voxtral 3 speech models and voice agent SDK, ranked by Artificial Analysis
Overview
Mistral AI releases Voxtral 3, three speech-to-text models and one text-to-speech model, plus a voice agent SDK that runs listening, reasoning, tool calling and speech in one real-time pipeline.
Mistral says the speech-to-text models support over 50 languages. The stack is available through Mistral's EU-hosted API or for self-deployment, which Mistral says lets organizations control where audio is processed and whether conversations are retained.
Artificial Analysis reports that Voxtral Small Transcribe 3 ranks #3 on its Speech to Text leaderboard with a 2.1% AA-WER Index, ahead of ElevenLabs Scribe v2 at 2.2%. It lists Voxtral 3 TTS at $13 per 1M characters, below Gemini 3.8 Flash TTS at $16.5 and Eleven v4 Turbo at $40, but above Simba 3.2 at $6.6.
Design Arena says Voxtral TTS 3 is available on its platform and claims 35+ languages and sub-second response times for real-time voice agents. Design Arena made that claim itself, and no independent measurement of response time is reported.
