Swahili is the most regular language in this list and the one whose pronunciation costs an English speaker least: five vowels that never change value, stress always on the second-to-last syllable, and a spelling that says exactly what it means. iLexiBox spends the on-ramp on the vowels and then moves fast, because very little stands between a beginner and a Swahili sentence.
The Swahili on-ramp is written by hand, not generated, and it is 196 cards long. Every card is spoken in a recorded Swahili 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. Make a text writes Swahili 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. Lexi talks back. The Translator fixes your mistakes as it translates and can give a simpler version at your level, and Writing marks what you wrote and says why.
Above the on-ramp sits the Course — a map of practice steps from A1 to C2 with grammar, vocabulary and a level test at the top of each level — and My words, where everything you save comes back on a spaced-repetition schedule in eight quiz styles.
The album is a photograph for every word, shelved by category, each caption written in Swahili 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.
The vowels are the whole of the early work, and the work is unlearning English. a is always ah, e is always eh and never ee, i is always ee and never eye, and no vowel is ever reduced to an uh however unstressed it is. That last habit is the hard one to break, and it is what makes an English speaker's Swahili hard to follow. Beyond the sounds, Swahili's real subject is the noun-class system — every noun belongs to a class, and the class agrees across the whole sentence — which the course meets in sentences rather than as a table of prefixes.
