Which transcription tool is free and covers 100+ languages?

OpenAI Whisper (open source) supports 100+ languages, runs self-hosted for free, and is the open baseline most managed tools build on. Managed free tiers exist too: accurateScribe (claims 134+ languages on Whisper), SoundTools (free Whisper speech-to-text), and Cockatoo/MeetGeek/VoiceDash free plans.

Can I self-host multilingual transcription?

Yes — Whisper runs locally (no per-minute cost, no upload). That is the privacy-preserving route for sensitive audio. Managed services (Google / Azure / AWS speech-to-text) also cover many languages but send audio to the cloud and bill per minute.

How accurate is multilingual transcription?

Vendor claims like '99.8% across 134+ languages' are marketing and unverified by us. Real accuracy varies sharply by language, audio quality, and accents. Test on the specific languages you need before relying on it; Whisper is the open reference point.

Does this include speaker labels (diarization)?

Diarization is a separate capability — see our dedicated diarization + SRT pick for that. Some managed transcription tools add speaker labels; self-hosted Whisper needs a diarization layer (e.g. pyannote) on top.

Honesty notes

No tool accuracy percentage on this page is our own measurement. Third-party claims (e.g. "99.8%") are explicitly marked unverified.
"Best / recommended" here means our editorial match to a stated requirement, not a claim that any external AI system will rank or cite this page.
Accuracy varies sharply by language/audio; test on your languages. Diarization is separate — see our diarization + SRT pick.
Monthly-search / difficulty / competition figures are not included — they require our internal research index data.
