Microsoft AI Introduces MAI-Transcribe-1.5: 2.4% WER on Artificial Analysis, Best-in-Class FLEURS Accuracy, and Up to 5x Faster Long-Audio Transcription

Last week Microsoft AI has announced MAI-Transcribe-1.5. It is the second iteration of the company’s in-house speech-to-text family. The model targets accuracy across 43 languages, accents, and noisy environments. The Microsoft team positions it for production transcription workloads.

What is MAI-Transcribe-1.5

MAI-Transcribe-1.5 is an automatic speech recognition (ASR) model. It takes audio as input and returns text. Microsoft built it in-house, not on a third-party base. The model handles 43 languages with a single system. It is optimized for diverse accents, dialects, and real-world acoustic conditions.

Microsoft is integrating it into Copilot, Teams, GitHub, and Dynamics 365 Contact Centre. It is also available in Foundry, Microsoft’s model platform.
