Transcribe Portuguese nowHow well Portuguese works on Sprechverlauf
Portuguese works in the free trial: three transcriptions of up to 10 minutes per calendar month, no account, as text with timestamps. It runs on Whisper Large v3 Turbo, a model trained on roughly 100 languages.
With a day pass, credit or Pro, Microsoft MAI-Transcribe-2 takes over. It separates speakers, so the transcript shows who said what — useful for interviews, meetings and conversations in Portuguese. Microsoft reports an average word error rate of 5.2% across the model's 60 languages (FLEURS benchmark); individual languages score above or below that.
What matters for Portuguese
Portuguese sounds different across Brazil, Portugal, Angola, and Mozambique. The models are trained on many varieties; the stronger the dialect and slang, the more the transcript drifts toward the standard language or mishears regional words.
Portuguese is close to Galician and Spanish. On short clips, automatic detection can mix them up — select Portuguese explicitly before you start.
Tips for better Portuguese transcripts
- In step two, pick "Portuguese" instead of automatic detection if the recording is short or starts with music.
- Record close to the microphone; a clip-on mic beats a built-in laptop mic by a wide margin.
- Overlapping speech hurts every recognizer. Short pauses between speakers help more than any editing afterwards.
- Check names, numbers and technical terms: click a timestamp to hear that exact passage.
Frequently asked questions
Can I transcribe Portuguese for free?+
Yes. The free trial transcribes Portuguese without an account: three files of up to 10 minutes per calendar month, as text with timestamps. Longer files and speaker separation start at €2.99, no subscription.
Does Sprechverlauf separate speakers in Portuguese?+
Yes, with a plan. Microsoft MAI-Transcribe-2 separates speakers in Portuguese too; the transcript then shows "Speaker 1", "Speaker 2" and so on. The free trial gives plain text.
Do I have to select Portuguese before starting?+
No, the language is detected automatically. Selecting it helps with very short recordings and because Portuguese is easily confused with Galician and Spanish.
Which files can I upload?+
MP3, WAV, M4A, OGG/Opus, FLAC, WebM, AAC, MP4, MOV — upload up to 100 MB or paste a direct link to the audio file. Download the result as Word, PDF, TXT, SRT or VTT.
