About
MAI-Transcribe-2-Streaming is a low-latency streaming transcription model built for real-time speech applications, delivering transcripts in 60 languages with automatic, continuous language detection. Rather than waiting for someone to finish speaking, it produces initial partial transcripts just over 100 ms after receiving audio, revises them as more context arrives, and commits stable text quickly. This allows voice applications to begin reasoning, calling tools, or displaying live transcripts while a person is still speaking. Microsoft reports that the model ranks No. 1 for both final and partial transcript accuracy on Artificial Analysis. MAI-Voice-2.1 complements it with multilingual text-to-speech across 23 languages and 26 locales, allowing a single voice to switch languages while maintaining the same speaker identity and adopting native accents.

About
Voxtral models are frontier open source speech‑understanding systems available in two sizes—a 24 B variant for production‑scale applications and a 3 B variant for local and edge deployments, both released under the Apache 2.0 license. They combine high‑accuracy transcription with native semantic understanding, supporting long‑form context (up to 32 K tokens), built‑in Q&A and structured summarization, automatic language detection across major languages, and direct function‑calling to trigger backend workflows from voice. Retaining the text capabilities of their Mistral Small 3.1 backbone, Voxtral handles audio up to 30 minutes for transcription or 40 minutes for understanding and outperforms leading open source and proprietary models on benchmarks such as LibriSpeech, Mozilla Common Voice, and FLEURS. Accessible via download on Hugging Face, API endpoint, or private on‑premises deployment, Voxtral also offers domain‑specific fine‑tuning and advanced enterprise features.
