How can you practice Brazilian Portuguese out loud?

Practice it in short, real exchanges, out loud. CiaoSpeak's Brazilian Portuguese course teaches everyday words like legal and valeu with a recording in a Brazilian accent, and in the Speak tab people across Brazil (a São Paulo baker, a Rio ride-app driver, your language-exchange partner Ana) ask you one question at a time. You answer by voice or typing, and the app tells you whether a Brazilian would understand you. Lessons are free; in the Speak tab, today's questions (up to five a day) are free too, and CiaoSpeak+ adds practice in any scene whenever you like. More words like this one: the Brazilian slang list.
