Understanding Portuguese transcription

Who transcribes Portuguese content?

Podcast producers, broadcasters, and video teams in Brazil and Portugal transcribe Portuguese interviews and episodes for editing, captions, and show notes. Researchers, legal professionals, NGOs working in Lusophone Africa, and diaspora media in countries like the United States, France, and Luxembourg also rely on Portuguese transcription.

Portuguese dialects and accents

Portuguese has two major standards: Brazilian Portuguese and European Portuguese, which differ noticeably in pronunciation, rhythm, and some vocabulary. African varieties spoken in Angola, Mozambique, and other Lusophone countries generally follow the European standard, while Brazil itself has distinct regional accents such as Carioca, Paulista, and Northeastern speech.

Where Portuguese is spoken

Portuguese is spoken in Portugal, Angola, Cape Verde, Guinea-Bissau, Mozambique, Sao Tome and Principe, Brazil, and parts of Namibia, Germany, France, Luxembourg, and Spain.
