Yes, two. Voxtral Mini Transcribe 2 for batch transcription with speaker diarization and context biasing and Voxtral Realtime for live streaming transcription with sub-200ms latency.
Yes, you can provide a voice sample as short as 3 seconds and Voxtral TTS, our text-to-speech model, will adapt to capture the speaker's tone, rhythm, and personality. You can also use preset voices or build your own voice library.
Transcription supports 13 languages including English, French, German, Spanish, Chinese, Hindi, Arabic, Portuguese, Russian, Japanese, Korean, Italian, and Dutch. Voice generation supports 9 languages with dialect-aware expressions in English, French, German, Spanish, Dutch, Portuguese, Italian, Hindi, and Arabic.
An example of combining Voxtral models to form a speech-to-speech pipeline is: Voxtral Realtime transcribes incoming speech, another Mistral LLM reasons over the transcript and determines a response, and Voxtral TTS generates spoken output. Each component is independently customizable and deployable. Cross-lingual voice adaptation means the pipeline can also handle live translation while preserving the speaker's accent and identity.
Yes, you can self-host Mistral Speech or deploy on Mistral Compute.
