Why use Mictoo for multilingual audio?
Multilingual audio that works well
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.

Transcribing French
Whisper handles French well, and the errors it does make cluster in three predictable places. Knowing them tells you what to skim when you proofread.
- Liaison
- Words run together in speech: les amis is spoken le-za-mi. The model usually gets it, but it can attach the linking sound to the wrong word on fast speech
- Elision
- J’ai, l’homme, qu’il. Apostrophes come back correctly in most cases; check them in proper nouns, where there is no dictionary to fall back on
- Nasal vowels
- Sans, bon, brun. These carry meaning and are the most common source of a wrong-but-plausible word
- Varieties
- Metropolitan, Quebec, Belgian, Swiss and West African French all work. Quebec vocabulary such as char for car or courriel for email transcribes fine; heavy joual is where it slips
- Worth doing
- Set the language explicitly rather than relying on auto-detect if the recording is under five minutes
Transcribing Spanish
The dialect spread is wider than in French, and Whisper is trained across it. What varies is which spelling it picks, not whether it understands.
- Voseo
- Vos tenes instead of tu tienes. Common in Argentina, Uruguay, Paraguay and much of Central America, and transcribed as spoken
- Seseo and distincion
- Gracias is spoken with an s across Latin America and with a th in most of Spain. Both come back spelled the same way, which is what you want
- Yeismo
- Calle sounds different in Madrid, Buenos Aires and Bogota. Spelling is unaffected
- Varieties
- Castilian, Mexican, Rioplatense, Caribbean, Andean, Chilean and US Spanish. Chilean and Caribbean speech at speed is the hardest case
- Worth doing
- Review names and place names. Regional vocabulary is handled better than proper nouns
Transcribing German
German gives the model two structural problems that no amount of audio quality fixes, because they are about how the language is written rather than how it sounds.
- Compound nouns
- Krankenversicherung, Geschwindigkeitsbegrenzung. Whisper mostly joins them correctly, but an unfamiliar compound can come back split into two words
- Separable verbs
- Ich rufe dich spaeter an. The prefix lands at the end of the clause, sometimes many words from the verb it belongs to
- Umlauts and eszett
- Returned properly rather than transliterated to ae, oe, ue and ss
- Varieties
- Standard German plus Austrian and Swiss. Austrian vocabulary such as Jaenner for January or Marille for apricot works; Swiss German dialect, as opposed to Swiss Standard German, is genuinely hard
- Worth doing
- Proofread technical compounds and any Swiss dialect passages first, they are where the errors concentrate
Frequently asked questions

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.
