MAI-Transcribe-1.5 is Microsoft’s speech-to-text model for 43 languages. Keyword biasing helps with domain terms, and Microsoft cites up to five times the speed of comparable models.
The endpoint accepts audio and returns text. Foundry access is a public preview without an SLA. Microsoft lists $0.36 per hour of audio. It is intended for transcription, not speech synthesis or audio-to-audio dialogue.
