The Challenge of doing Portuguese subtitles

Portuguese (Português) is a Romance language spoken by 250 million people in Portugal, Brazil and other Portuguese-rooted countries. As Portuguese is the most widespread language in South America, Portuguese video content are more and more in demand in the web and TV industry. Yet, this Latin-based language can be hard to transcribe or translate, since Portuguese speakers show various accent differences (especially in Brazil) which makes it hard to understand them. So Portuguese subtitlers need to know how to discriminate many pronunciation variations. Fortunately, our Portuguese subtitle experts are aware of the specificities of the Portuguese language and will provide you the best subtitles.
