Microsoft MAI-Transcribe-2 Goes GA in Foundry: One Speech Model for 60 Languages With Built-In Diarization, an Hour of Audio in About 10 Seconds, $0.10 per Hour Through 2026
Microsoft AI announced on November 12 that MAI-Transcribe-2, its in-house speech-to-text model, is generally available in Microsoft Foundry for production use at $0.10 per hour of audio, a limited-time price through the end of 2026. The model entered public preview on September 3 and covers 60 languages in one model, with built-in speaker diarization, word-level timestamps and keyword biasing. Microsoft says it transcribes an hour of audio in about ten seconds of inference and averages 3.4% word error rate on the top 25 FLEURS languages.

Key Takeaways
- From preview to production: public preview on September 3, general availability in Microsoft Foundry on November 12 (Microsoft Learn docs)
- Price: $0.10 per hour of audio, which Microsoft labels a limited-time offer through December 31, 2026; check the official pricing page for later rates
- One model, 60 languages: automatic language identification, code-switching such as Hinglish and Spanglish, and accuracy held in noisy audio
- Built in rather than bolted on: speaker diarization, word-level timestamps, keyword biasing (phraseList) and clean or verbatim transcript styles
- Speed and accuracy are Microsoft-reported: about 10 seconds of inference per hour of audio, 10x faster than GPT-Transcribe, 7x faster than Scribe v2 and 5x faster than Gemini 3.5 Transcribe; 5.2% average WER across all 60 FLEURS languages
