Summary

Voxtral Mini Transcribe 2 is Mistral’s optimized transcription service for audio files. The API alias voxtral-mini-latest supports timestamps, speaker diarization, and context terms. With context_bias, you can supply up to 100 words or phrases to improve names and domain vocabulary. The documentation says context biasing is optimized for English, while support for other languages remains experimental.

Voxtral Mini Transcribe 2 processes audio files with timestamps, speaker separation, and context terms. Mistral supports streaming in the transcription service, but documents Voxtral Mini Transcribe Realtime as the separate live path. Batch and real time therefore remain distinct model paths.

Independent evaluation. Artificial Analysis directly tested the named API endpoint; audio-duration-weighted WER across AA-AgentTalk (50%), VoxPopuli-Cleaned-AA English (25%), and Earnings22-Cleaned-AA (25%), about eight hours total. Current normalizer AA-WER v2.2.

Methodology
Vendor-reported result. Mistral's announcement explicitly attributes an approximately 4% FLEURS WER to Voxtral Mini Transcribe V2. The numeric score 4 is only a representation of that approximate claim, not an exact or unrounded result. Mistral does not publish the sample denominator, confidence interval, or full evaluation configuration here.
Context
This is an explicitly approximate vendor claim, not an exact measured value. The source does not provide the evaluation sample denominator, confidence interval, or enough protocol detail to establish comparability with other FLEURS results. Do not interpret 4% as precise or compare it directly with Artificial Analysis AA-WER.

fleurs-evaluation-denominator-protocol-and-confidence-interval

Note

Mistral publishes an approximate model-specific 4% FLEURS WER claim, recorded above as approximate. The exact unrounded score, sample denominator, confidence interval, and full evaluation protocol are not published in the cited announcement.

Not published

immutable-evaluated-api-snapshot

Note

The paper names Voxtral Mini Transcribe V2 but does not disclose the immutable API/model snapshot evaluated; the exact product name is the available profile bridge.

Not published

evaluated-denominator-and-confidence-interval

Note

The paper tables do not publish the metric-specific evaluated sample count or confidence intervals; no denominator was inferred from corpus sizes.

Note

Neither Omi nor Vals names an immutable serving revision for the Voxtral API call. The evaluators test different datasets and tasks.
