## Summary

Microsoft announced on October 1, 2026 a new suite of voice AI tools that can return text while a speaker is still talking. The transcription service, called MAI-Transcribe-2-Streaming, shows tentative text about 100 milliseconds after audio arrives and refines it as the utterance continues. It supports 60 languages, including Japanese, while the companion text‑to‑speech models – MAI-Voice‑2.1 and the faster MAI-Voice‑2.1‑Flash – cover 23 languages but currently lack a Japanese voice option.

Pricing is published in US dollars: transcription costs $0.54 per hour of audio (introductory rate through the end of 2026), standard voice generation $22 per million characters, and Flash voice generation $15 per million characters. The services are in public preview and Microsoft warns they are not recommended for production use. Developers can try them via the MAI Playground or integrate them through Microsoft Foundry, but they must verify language support and cost implications for their applications.

Potential use cases include live subtitles for meetings or lectures, real‑time note taking, and quick voice responses in interactive apps. Accuracy for Japanese proper nouns, dialects, or noisy environments has not been independently verified, so adopters should test the tools before committing to production workloads.

## Key points

- Microsoft’s MAI-Transcribe-2-Streaming returns tentative text within 100 ms of audio input
- Pricing: $0.54 per hour for transcription; $22/$15 per million characters for standard/Flash voice generation
- Transcription supports 60 languages (including Japanese); voice generation supports 23 languages, currently no Japanese voice option

## Why it matters

Near‑instant transcription cuts latency for interactive apps, enabling smoother subtitles, live notes and faster voice‑driven experiences, while pricing and language limits shape early adoption.
