# MAI-Transcribe-2-Streaming launch notes: Voice Benchmark Profile

> Microsoft launched streaming transcription in 60 languages at an introductory $0.54 per hour through the end of 2026.

- Scope: Provider-reported languages, availability, introductory audio-duration price, and first-hypothesis timing
- Measurement lanes: Voice experience, Latency
- Primary metric: Language coverage and USD per hour of audio
- Available evidence: Provider specifications published October 1, 2026; evaluator measurements are linked separately
- Owner: Microsoft AI
- Source snapshots refreshed: 2026-09-30

## Interpretation limit

Microsoft reports first hypotheses just over 100 ms after receiving audio. That timer differs from transcript latency measured after detected speech end. The non-streaming model's FLEURS result does not establish this streaming release's accuracy.
