Brazilian vs European Portuguese
Brazilian Portuguese differs noticeably from the European Portuguese spoken in Portugal. Brazilian speech tends to use more open vowels, palatalises the sounds in words like "dia" and "tia", and favours "você" for "you". Vocabulary and everyday expressions differ too. ConvertSpeech is tuned specifically for the Brazilian variety on this page.
If your recording is European Portuguese from Portugal or Africa, use our separate Portuguese page, which is set up for pt-PT. Choosing the variety that matches your audio gives the most accurate transcript — though in every case, clean recordings matter more than anything else.
Tips for accurate Brazilian Portuguese transcription
- Record with a good microphone and low background noise for the best accuracy.
- Match the variety to your audio: use this Brazilian page for pt-BR, the Portuguese page for pt-PT.
- One speaker at a time transcribes best; heavy overlap reduces accuracy.
- For interviews, enable speaker detection (a free registered feature) to label each speaker.
