Microsoft Foundry adds MAI-Transcribe-1.5 to the model catalog in public preview, Microsoft's next-generation speech-to-text model. The release adds improved accuracy with noticeably lower word error rate on long-tail locales than the previous generation, plus faster real-time and batch transcription with predictable latency. Target workloads include call center analytics, media captioning, voice agent transcription, and meeting recording. MAI-Transcribe-1.5 is available via Global Standard deployments with Foundry-native governance, regional support, and content safety controls shared across MAI models. It is available through Azure Speech.
