Brazilian Portuguese TTS audio on tts.audio runs on four MAI Voice 2 voices: Caio (male), Luana (female), Pedro (male), and Rafael (male). All four produce Brazilian Portuguese, the variety spoken by roughly 215 million people in Brazil and the de facto standard for Brazilian broadcast media, music, and online content. Brazilian and European Portuguese differ enough in pronunciation, vocabulary, and grammar that audio produced for one is noticeably foreign to the other. If your audience is Brazilian, use this page. If your audience is Portuguese (Portugal, PALOP countries), switch to the pt-PT page and use Rui. Caio, Luana, and Pedro support the full eighteen MAI expressive styles. Rafael supports a thirteen-style set, missing five of the darker emotional colors. Use cases for Brazilian Portuguese TTS include YouTube voiceovers for the Brazilian market, e-learning localization, accessibility audio for Brazilian government and corporate documentation, and pronunciation reference for English-speaking learners of Portuguese.
