Learn Indonesian by speaking it

Indonesian is the best-kept secret in language learning. It has around 200 million speakers, it is the national language of the fourth most populous country on earth, and it is dramatically easier for an English speaker than anything else in this app.

What it does not have

No tones. No grammatical gender. No case system. No verb conjugation for person or tense. No plural agreement, and you can indicate a plural by saying the word twice, which is exactly as pleasant as it sounds. Articles are largely absent. The spelling is close to perfectly phonetic, and the alphabet is the one you already use.

The usual first-year grind, where you cannot say anything because the machinery is not built yet, is largely absent. People get to real conversation faster here than in any other language on this list.

Which means the bottleneck arrives sooner

That is genuinely the point. In French or Russian you can spend a year with grammar as an alibi for not speaking. Indonesian removes the alibi within weeks, and what is left is the actual difficulty, which was always going to be having a conversation with somebody in real time.

Sessions here are unscripted conversation. The tutor talks back out loud, you interrupt it, you lose the thread and recover. Behind it sits an authored CEFR syllabus of 316 items from A1.1 to C1, of which 113 are capabilities: concrete things you can do rather than grammar points.

Why the tutor hearing you still matters

Indonesian pronunciation is forgiving, but three habits mark an English speaker immediately: gliding the vowels, reducing the unstressed ones to a schwa, and aspirating p, t and k with a puff of air that Indonesian does not use.

All three transcribe perfectly. Say selamat with English vowel reduction and the transcript reads selamat. So a text-based app can never mention it, and most learners go years without anybody doing so.

Here the audio goes to the model directly and comes back as audio, so the tutor is responding to how you sound.

Formality, which is where the real subtlety lives

The grammar being simple does not make the language simple. Indonesian carries a great deal of social nuance in word choice, in pronouns and in indirectness, and being blunt in perfectly correct Indonesian is a much easier mistake to make than being ungrammatical.

That is exactly the sort of thing that only shows up in conversation, and the five tutors give you real range: Yogyakarta is measured and polite, Surabaya is direct, Makassar more emphatic still.

Travel

Travel Mode changes the app for the length of a trip: rehearsal before you go, one real-world mission a day while you are there set in the city you are in, and a debrief with your tutor afterwards.

Indonesia is close to ideal for it. Effort is met with warmth almost everywhere, the everyday transactions are simple enough to rehearse in a morning, and the country is large and varied enough that a daily mission stays interesting for weeks.

The five Indonesian tutors

Every language has five, each from a different place and each sounding like it. You can switch whenever you like, and the app remembers where you are regardless of who you talk to.

• PutriJakarta

  Clear standard Bahasa Indonesia with a relaxed, urban delivery.

• SariBandung

  Standard Indonesian carried with the soft, melodic warmth of Sundanese West Java.

• ArjunaYogyakarta

  Standard Indonesian spoken with the gentle, measured politeness of Central Java.

• RinaSurabaya

  Standard Indonesian delivered with the direct, bright energy of East Java.

• BayuMakassar

  Eastern Indonesian from South Sulawesi, with firm, percussive consonants and a direct, emphatic delivery.

What English speakers usually find hard

These are drawn from the pronunciation patterns the tutor listens for in Indonesian. Because it hears your voice rather than a transcript of it, they are things it can actually notice and work on with you.

Five vowels that stay put

Short, pure, and no English-style gliding. The English o in go moves through two sounds and the Indonesian o does not. Holding vowels still is half of sounding natural, and it is mostly a matter of resisting an English habit rather than learning anything new.

One letter e, two sounds, no clue which

Indonesian writes both a full e and a schwa with the same letter, and nothing in the spelling tells you which one a word takes. It has to be learned per word, and it is the one place where the otherwise honest spelling system lets you down.

c is always ch

Cinta is chinta and bicara is bichara. Never an s, never a k. Similarly ny is a single palatal sound like the Spanish ñ, and ng is a single sound that can start a word, which English never does.

Final k becomes a catch in the throat

A word-final k is usually not released as a k at all but as a glottal stop. Tidak comes out closer to tida with a catch at the end, and anak likewise. English speakers release it fully, which sounds foreign.

Stress sits on the second-to-last syllable

Selamat is se-LA-mat and bahasa is ba-HA-sa. Just as important, unstressed vowels keep their full value: it is not sə-LA-mət. English vowel reduction is the single most persistent accent marker here, as it is in Spanish and Italian.
