Tips for multilingual accuracy

  • For very short clips, pin the primary language explicitly.
  • For mid-sentence code-switching, use Auto-detect.
  • Review proper nouns and place names, which often cross languages.
  • Translate after transcribing rather than before.

What makes multilingual recognition difficult

Language ID on short clips
Very short clips may be assigned the wrong language.
"Choose the primary language"
Code-switching mid-sentence
Short switches can be missed or normalised, so bilingual output should be reviewed.
"Vamos a la meeting"
Named entities
Proper nouns can look like foreign words. Review them post-transcription.
"Björk / San José"
Non-Latin scripts
Japanese, Chinese, Korean, Arabic, and Cyrillic scripts are supported; review punctuation and names.
"昨日 / вчера"

Frequently asked questions

Which languages are available?

The upload and translation controls currently offer 36 languages, including English, French, Spanish, German, Portuguese, Italian, Dutch, Polish, Russian, Ukrainian, Japanese, Chinese, Korean, Arabic, Hebrew, Hindi, Turkish, and others. See the language picker for the full list.

Does it handle code-switching?

It can transcribe many recordings that switch languages. Use Auto-detect for bilingual conversations and review short switches, proper nouns, and ambiguous phrases.

Can I translate the transcript?

Yes. After transcription, pick any target language and click Translate. GPT-4o-mini handles the translation and it appears alongside the original.

How accurate is auto-detect?

It works best when the recording contains enough clear speech. For short or noisy audio, choose the primary language explicitly and review the first draft.

Is multilingual transcription free?

Yes. Files up to 25 MB can be transcribed anonymously or up to 180 MB when signed in. No watermark and no per-minute fee.

Are my audio files stored?

No. Audio streams to the transcription provider, gets processed once, and is dropped. Transcripts persist only on signed-in accounts.
