Live transcription for Korean meetings: MAI-Transcribe-2-Streaming

For a live Korean meeting, MAI-Transcribe-2-Streaming is worth a trial, but I could not confirm Korean support from the page I read. Microsoft's Oct 1, 2026 post says 60 languages with automatic language detection and first hypotheses in just over 100ms. It does not, in the text I read, list the 60 languages, so check that Korean is on the list before you plan around it. For meeting recordings after the fact, Sume can transcribe a hosted clip with a Korean language hint.

What Microsoft states

A Korean meeting test

Mixed-language meetings are where auto detection is tested. A Korean meeting often drops English product names, acronyms and numbers into the sentence. Before you pick a tool, record a real 10-minute excerpt and score it:

• Count wrong or missing proper nouns and product names per 100 words.
• Check how numbers, dates and units are written.
• Look at partial transcripts as well as final ones: a live caption that rewrites itself often is hard to read.
• Test two speakers who talk over each other, and a quiet speaker.
• Try the same clip with the language set explicitly and with auto detection.

The Sume route for recordings

Sume does not do live streaming transcription. POST /v1/video-inspect with transcribe: true reads one clip already on media.sume.com (import it first with POST /v1/media-imports) up to 1,800 seconds. Send language_code as a hint (the docs give ko as an example) or omit it to auto-detect, and segmentation.mode: "sentence" for gap-free sentence segments.

Cost for a 30-minute recording: 30 x $0.01 = $0.30 for the transcript, plus the job's compute, and a 5.5% platform fee on customer spend. MAI's introductory live rate for the same 30 minutes is 0.5 x $0.54 = $0.27. They are different products: one is live, the other works on a finished file.
