## Speech and voice evidence

[Voxtral 3 launch evaluation](/voice-benchmarks/voxtral-3-launch-evaluation)

All results are Mistral-run. FLEURS macro-averages use CER for Japanese, Korean, Thai, and Chinese. Diarization averages AMI-IHM, AMI-SDM, Switchboard, Switchboard CallHome, and AISHELL-4, with 30-minute AMI and AISHELL versions. Realtime rows trade latency for accuracy; the Mini Transcribe 3 row on FLEURS 35 is an offline baseline. Voice Code Bench is a BeSimple AI test of numbers and names in support calls; the multilingual and expressive scores are judged by gemini-3.8-flash. The launch post and docs disagree on TTS language count (35+ vs 9) and realtime minimum latency (240 ms charted, 80 ms documented). Competitor rows from Mistral charts are not carried here. These results do not enter text-model or voice-agent rankings.

| Metric | Result |
| --- | --- |
| Voice Code Bench faithful clips | 79.7% |
| Pronunciation control accuracy | 86.8% |
| Multilingual judge score, 11 languages | 3.16 / 5 |
| Expressive English judge score | 3.13 / 5 |

Mistral launch charts retrieved October 20, 2026. Higher is better. Pronunciation and judge scores are Mistral internal evaluations; voice results are display-only.
