Voxtral Transcribe 2 by Mistral

Mistral AI has introduced Voxtral Transcribe 2, a set of two advanced speech-to-text models. These models are built for high-quality transcription, accurate speaker identification, and very fast processing.

Benefits

Voxtral Transcribe 2 offers several advantages. It provides accurate transcriptions with speaker diarization, meaning it can tell who is speaking. It also includes context biasing to improve accuracy for specific terms and word-level timestamps, which are useful for creating subtitles. The models are designed to be robust even in noisy environments. Voxtral Mini Transcribe V2 can handle audio files up to three hours long and supports 13 languages, showing strong performance even in languages other than English. Voxtral Realtime offers very low latency, making it suitable for live applications, and can achieve transcription delays as low as 200 milliseconds.

Use Cases

These models are useful for a variety of voice applications. They can be used for meeting intelligence tools that summarize discussions, voice agents and virtual assistants that understand spoken commands, and automating tasks in contact centers. They are also helpful for the media and broadcast industry to generate live multilingual subtitles. Additionally, they can be used for compliance and documentation purposes. Both models can be deployed securely on-premise or in private clouds, supporting GDPR and HIPAA compliance.

Vibes

Voxtral Transcribe 2 has shown industry-leading accuracy, outperforming other models like GPT-4o mini Transcribe and Gemini 2.5 Flash on benchmarks. Its real-time version matches the accuracy of the mini version at a 2.4-second delay and maintains near-offline accuracy at a 480ms delay.

Additional Information

Voxtral Realtime is available as open-weights under the Apache 2.0 license. The models are designed to be efficient, with the real-time version having a 4B parameter footprint suitable for edge devices and privacy-focused applications. An audio playground is also available for users to test Voxtral Transcribe 2 directly.
