Portuguese is most often started by people who already have some Spanish, and the place they come unstuck is the sound rather than the grammar. iLexiBox puts the nose first: Portuguese sends a great many of its vowels through it, the spelling signals that in three different ways, and not one of them is obvious from Spanish or from English.
The Portuguese on-ramp is written by hand, not generated, and it is 200 cards long. Every card is spoken in a recorded Portuguese voice, and what you get right is scheduled for review rather than shown again at random.
Three of the pronunciation cards, exactly as the course teaches them:
Once you are reading, the level is the point. The Text Generator writes Portuguese at the CEFR level, length, topic and format you ask for, so the step up is a setting rather than a new book. Speaking scores you word by word as you read aloud. The Conversation Partner talks back. The Translator explains a sentence instead of replacing it, and the Corrector marks what you wrote and says why.
Above the on-ramp sits the Path — a station map from A1 to C2 with grammar, vocabulary and checkpoint stations — and Words & Notes, where everything you save comes back on a spaced-repetition schedule in seven quiz styles.
The album is a photograph for every word, shelved by category, each caption written in Portuguese and spoken in a real recorded voice rather than synthesised on the fly. It doubles as a game: see the picture, spell the word. Free to replay.
An m at the end of a word is not an m at all — the lips never close, and the vowel goes out through the nose instead. The same happens to an n inside a word before another consonant, in canto and mundo, where the n itself disappears. And ão, the ending you will meet more than any other, is an ow through the nose finished with a hum, never an o and an n said one after the other. Nasality is not something a page can teach, so each of these is a card with a recorded Brazilian voice — the same voice the album is spoken in.
