Voxtral Transcribe 2 is a family of next-generation speech-to-text models designed to provide state-of-the-art transcription quality, speaker diarization, and ultra-low latency for a wide range of applications. The product includes two distinct models: Voxtral Mini Transcribe V2 for batch transcription tasks and Voxtral Realtime specifically engineered for live applications requiring immediate processing. It serves developers, businesses, and organizations that need reliable, efficient, and accurate conversion of spoken language into written text, supporting use cases from meeting intelligence and contact center automation to media broadcasting and compliance documentation. The primary purpose is to deliver industry-leading accuracy at a fraction of the cost while enabling real-time voice interactions through configurable low-latency capabilities, all available via API or as open-weights for flexible deployment.
Traditional speech-to-text systems often struggle with balancing accuracy, speed, and cost, creating significant pain points for developers and enterprises. Many existing solutions force a trade-off between high-quality batch transcription and real-time processing, leaving applications like live voice agents or instant subtitling with subpar performance. Users face challenges with inaccurate transcription of domain-specific terminology, difficulty distinguishing between multiple speakers in recordings, and prohibitive costs when processing large volumes of audio content. Additionally, privacy concerns limit deployment options for sensitive data, while multilingual support frequently lags behind English-language performance, creating barriers for global applications.
The first major feature group centers on real-time transcription capabilities through Voxtral Realtime, which uses a novel streaming architecture that processes audio as it arrives rather than in chunks. This approach enables configurable latency down to sub-200 milliseconds, unlocking responsive voice-first applications that require immediate feedback. At 480 milliseconds delay, the model maintains within 1-2% word error rate compared to offline accuracy, making it suitable for voice agents and live subtitling. The technical implementation involves a 4B parameter footprint optimized for edge device deployment, ensuring privacy and security while delivering strong multilingual performance across 13 languages including English, Chinese, Hindi, Spanish, and Arabic.
The second major feature group encompasses advanced transcription and diarization capabilities in Voxtral Mini Transcribe V2, which delivers significant improvements in accuracy across languages and domains. This model achieves approximately 4% word error rate on the FLEURS benchmark while costing only $0.003 per minute, representing the best price-performance ratio of any transcription API available. It outperforms competitors like GPT-4o mini Transcribe, Gemini 2.5 Flash, Assembly Universal, and Deepgram Nova on accuracy metrics while processing audio approximately three times faster than ElevenLabs' Scribe v2 at one-fifth the cost. The model maintains robust performance in challenging acoustic environments such as factory floors and busy call centers through noise robustness features.

Additional capabilities include speaker diarization that generates transcriptions with speaker labels and precise start/end times for meeting transcription and interview analysis, though with overlapping speech the model typically transcribes one speaker. Context biasing allows users to provide up to 100 words or phrases to guide the model toward correct spellings of names, technical terms, or domain-specific vocabulary, particularly useful for proper nouns and industry terminology. Word-level timestamps enable precise start and end timestamps for each word, supporting applications like subtitle generation and audio search, while expanded language support covers 13 languages with non-English performance significantly outpacing competitors. Longer audio support processes recordings up to three hours in a single request.
The product works through two specialized models with distinct technical approaches: Voxtral Realtime employs a streaming architecture purpose-built for live applications where latency matters, transcribing audio as it arrives rather than using chunk-based adaptations of offline models. Voxtral Mini Transcribe V2 utilizes batch processing optimized for accuracy and efficiency, delivering state-of-the-art transcription with speaker diarization, context biasing, and word-level timestamps. Both models share multilingual capabilities across 13 languages and support privacy-first deployment through on-premise or private cloud setups, with Voxtral Realtime available as open-weights under Apache 2.0 license for edge deployment.
Benefits and measurable outcomes include industry-leading accuracy at the lowest price point, with Voxtral Mini Transcribe V2 achieving the lowest word error rate while costing only $0.003 per minute. Users gain the ability to process audio approximately three times faster than competing solutions while matching quality at one-fifth the cost, enabling large-scale transcription projects previously limited by budget constraints. The sub-200 millisecond latency of Voxtral Realtime unlocks new classes of voice-first applications, allowing developers to build responsive voice interfaces that feel natural and immediate rather than delayed or disjointed.
Concrete use cases include meeting intelligence applications that transcribe multilingual recordings with speaker diarization clearly attributing who said what and when, enabling annotation of large volumes of meeting content at industry-leading cost efficiency. Voice agents and virtual assistants benefit from connecting Voxtral Realtime to LLM and TTS pipelines for responsive conversational AI with sub-200ms transcription latency. Contact center automation utilizes real-time call transcription enabling AI systems to analyze sentiment, suggest responses, and populate CRM fields while conversations are still happening, with speaker diarization ensuring clear attribution between agents and customers.
Target users include developers building voice applications, enterprises requiring meeting transcription and contact center automation, media companies needing live multilingual subtitles, and organizations with compliance documentation requirements. Integrations work with existing LLM and TTS pipelines, while the tech stack supports API access, open-weights deployment via Hugging Face, and private cloud implementations. Pricing plans include Voxtral Mini Transcribe V2 at $0.003 per minute via API and Voxtral Realtime at $0.006 per minute via API, with both models supporting GDPR and HIPAA-compliant deployments through secure on-premise or private cloud setups for sensitive data handling.
The primary value of Voxtral Transcribe 2 lies in delivering state-of-the-art transcription quality with unprecedented efficiency, enabling both real-time and batch processing applications through specialized models optimized for their respective use cases. By combining industry-leading accuracy, multilingual support across 13 languages, configurable low latency, and privacy-first deployment options, the product addresses critical pain points in speech-to-text technology while maintaining the lowest price point in the market. This combination of performance, flexibility, and cost-effectiveness transforms how organizations implement voice workflows across diverse applications from live voice agents to large-scale meeting transcription projects.
