Speaker diarization
Voxtral Mini Transcribe V2 generates speaker-labeled transcripts with precise start and end times, which is useful when you need to know who said what and when.
Voxtral Transcribe 2
Voxtral Transcribe 2 is Mistral AI’s speech-to-text family for batch and live transcription. It combines diarization, timestamps, multilingual support, and an audio playground in Mistral Studio for testing before integration.
Overview
Voxtral Transcribe 2 is Mistral AI’s speech-to-text offering, introduced as two next-generation models for transcription: Voxtral Mini Transcribe V2 for batch transcription and Voxtral Realtime for live applications. The launch focuses on transcription quality, speaker diarization, low latency, and language coverage rather than on a broader conversation or agent platform.
The product page says Voxtral Mini Transcribe V2 provides state-of-the-art transcription with diarization, context biasing, and word-level timestamps in 13 languages, while Voxtral Realtime is designed for streaming audio with latency configurable down to sub-200ms. Mistral also says the Realtime model is open-weights under Apache 2.0, and that an audio playground in Mistral Studio lets users test transcription with diarization and timestamps before building against the API.
The source positions Voxtral for workflows such as meeting transcription, voice agents, contact center automation, media subtitling, and compliance documentation. Pricing details in the article indicate API access for both models, with Mini Transcribe V2 at $0.003 per minute and Realtime at $0.006 per minute, plus an open-weights release for Realtime on Hugging Face.
Key capabilities
Context biasing
You can provide up to 100 words or phrases to bias the model toward names, technical terms, and other vocabulary that standard transcription systems may miss.
Word-level timestamps
The model can return timestamps for each word, supporting subtitle creation, searchable archives, and time-aligned content workflows.
Expanded multilingual support
Both models support 13 languages: English, Chinese, Hindi, Spanish, Arabic, French, Portuguese, Russian, German, Japanese, Korean, Italian, and Dutch.
Batch and live modes
Voxtral Realtime is built for live audio and supports latency configurable down to sub-200ms, while Mini Transcribe V2 is positioned for batch transcription.
Audio playground in Studio
The product description highlights an audio playground in Mistral Studio for immediate testing with diarization, timestamps, and audio file uploads.
Common use cases
Meeting notes and recaps
Transcribe recurring meetings with speaker labels and timestamps so teams can review decisions, assignments, and discussion flow after the call.
Voice agents and assistants
Power conversational agents and assistant experiences that need transcription latency low enough to keep voice interactions responsive.
Contact center workflows
Process customer support or sales calls as they happen, using diarization to separate agent and customer speech for later analysis or CRM entry.
Media and subtitles
Generate live or near-live subtitles for multilingual media, where low latency and word-level timing help align speech with on-screen captions.
Compliance and audit records
Record regulated or sensitive conversations with diarization and timestamps to create clearer audit trails for review and documentation.
Pros and Cons
Pros
- Offers both batch and low-latency transcription options under one product family.
