Microsoft AI released MAI-Transcribe-1.5, a multilingual speech-to-text model covering 43 languages with a best-in-class Word Error Rate on the FLEURS benchmark. The model includes keyword biasing that improves recognition of domain-specific terms by up to 30% on FLEURS, and can transcribe an hour of audio in under 15 seconds. It is being integrated into Copilot, Teams, GitHub, and Dynamics 365 Contact Centre, and is available via Foundry.

## Evidence

Verbatim from https://microsoft.ai/news/mai-transcribe-1-5more-accurate-context-aware-and-built-for-production/:

> MAI-Transcribe-1.5 can now bias its predictions toward a list of domain specific keywords provided by the user. The model does not blindly force matches, it uses the shared context to decide when keyword biasing should apply.
