Mandarin tone practice with AI feedback · iOS & Android
Your words. Your voice.
Know which tone you actually said.
Add the words you're learning right now - this week's chapter, yesterday's conversation - and say them out loud. Atone's AI hears which tone came out, corrects the ones you got wrong, and shows you the pairs you keep mixing up.

Inside the app



Your personal error map
Most learners don't make random tone mistakes - they make the same mistake, thousands of times, without hearing it. Atone's Tone Confusion Analysis maps exactly what your voice does when each tone is the answer: which tones you swap, on which words, and how often.
So instead of practicing everything harder, you fix the one habit that's actually in your way.

How it works
See a character or pinyin and record yourself saying it - real production practice, not multiple choice.
Atone's speech AI reads the pitch contour of your voice and identifies the tone you actually produced.
Correct? Next word. Wrong? See the tone you produced next to the one you were aiming for - and every miss feeds your personal confusion map.
Smart card selection knows which word you need next. Your ten minutes go to the tones you keep missing - not the ones you nailed weeks ago.
Twenty focused minutes at your desk or two in a queue, out loud or completely silent - there's a way to practice that fits, so the day you can't record isn't a day you skip.
Each word carries its own accuracy. Sort a deck by score and you always know exactly what to practice next.
Built differently
Almost every Chinese learner starts with the same shortcut: memorize the word, wing the tone. Atone is where you make that right - the name is a promise.
Every miss is recorded, mapped, and fed straight back into what Smart puts in front of you next. In Atone, a wrong tone is the most useful data you produce.
Atone tells you which tone your voice actually produced - so every attempt ends with something concrete to change, not just a score.
All HSK 1–9 decks are included free, and Smart mode plans your reviews from day one. Add your own words whenever you're ready.
Guides
Practical guides written for the questions Chinese learners actually search - each one ends with a way to put the answer into practice.
A four-step method that sticks: train your ear, speak with feedback, drill real words, and hunt down your own error pattern.
Read the guide →Recognition quizzes aren't enough. What separates a real tone trainer from a flashcard app with audio — a checklist for choosing one.
Read the guide →Why two-syllable combinations are the highest-leverage tone drill in Mandarin, the 20 patterns, and a practice plan that targets your weak ones.
Read the guide →How AI identifies your Mandarin tones from a recording, what it can and can't catch, and how to use it well.
Read the guide →If the four tones all sound the same to you, your ear needs training — not talent. Here is why, and the loop that fixes it.
Read the guide →The textbook "dipping tone" is a half-truth. What tone 3 really sounds like in speech, the two rules that tame it, and why it blurs with tone 2.
Read the guide →The 3-3 rule, the half-third, and the shape-shifting 不 and 一 — every tone sandhi rule that matters, with why pinyin hides them.
Read the guide →Your textbook words, your HSK list, the words from yesterday's conversation — drill the tones of vocabulary you'll actually use, and track accuracy word by word.
Read the guide →Building the deck yourself is half the learning. The right size, one source per deck, the words that almost fooled you — decks you'll actually finish.
Read the guide →A first-week guide: what each tone sounds like, English anchors that make them click, and the neutral tone everyone forgets.
Read the guide →You know the words, you've studied for years — and you still get blank stares. The fix is finding, and then dismantling, your fossilized tone errors.

FAQ
Mandarin has four main tones - high-flat (mā), rising (má), low/dipping (mǎ) and falling (mà) - plus a light neutral tone. The tone is part of the word: the same syllable with a different tone is a different word. Learn more →
Tone pairs are the 20 two-tone combinations that cover almost every two-syllable Mandarin word. Drilling pairs trains the transitions between tones - the part that falls apart in real sentences. Learn more →
Because the textbook 'dipping' contour almost never appears in real speech - tone 3 is usually just a low tone, and before another third tone it turns into a second tone (你好 = ní hǎo). Learning it as 'low' fixes most of the struggle. Learn more →
Tone sandhi are the rules that change tones when words meet: 3-3 becomes 2-3, tone 3 loses its rise before other tones, and 不 and 一 shift tones depending on what follows. Pinyin doesn't write these changes - you have to drill them. Learn more →
Pair recognition practice (see a word, name its tone) with speaking practice that tells you what you actually produced. Atone covers both: a Recall session has you name the tone, and a Speak session records your voice and uses AI to identify the tone you produced. Learn more →
Your brain learned to treat pitch as emotion, not meaning - so it filters tones out. Forced-choice drills with instant feedback retrain that filter, usually within weeks of short daily practice. Learn more →
Yes. Tones are pitch shapes, and speech AI can extract the pitch contour from your recording and classify which tone you actually produced. Atone tells you your tone vs. the correct tone on every attempt. Learn more →
For intermediate learners it's almost always fossilized tone errors - systematic habits you can no longer hear yourself. Atone's Tone Confusion Analysis maps exactly which tones you swap so you can fix them one at a time. Learn more →
Small enough to finish (15-30 words), built from one source (a chapter, a conversation), with tone-confusable pairs included - and built by you: creating the deck yourself measurably boosts memory (the generation effect). Atone's dictionary makes it take minutes, and Smart mode handles the review schedule. Learn more →
In Atone, yes - type any word and the built-in dictionary (100,000+ entries) fills in characters, pinyin and meaning, so you can build custom decks around your course or HSK level. Atone Pro also imports vocabulary lists straight from Pleco, Quizlet and other apps, so a list you already keep becomes a tone deck without retyping. Every word tracks its own accuracy so you always know what to drill next. Learn more →
Yes, with Atone Pro. Import a vocabulary list from Pleco, Quizlet and other apps, and Atone turns it into a practice deck - so the words you have already collected become tone practice without retyping them. Learn more →
Two independent choices. The session type sets what each rep asks of you: Recall shows a character and you pick its tone, Speak shows the pinyin and you record it, and Recall & Speak shows a character and you record it, so reading and pronunciation train together. The practice mode sets which cards come up: Smart schedules your weakest words for you, while Shuffle and Ordered let you run a deck the way you want. Learn more →
Yes - it's the default. Smart decides which cards come up next, automatically scheduling reviews of the words you're weakest on, Anki-style, without you managing a queue. Shuffle and Ordered are there for when you'd rather run through a deck yourself. Learn more →
Yes - decks for every HSK level 1 through 9 are included free. Practice them in any mode, or use them as a starting point and build custom decks around your own course. Learn more →
Atone is a free download on iOS and Android with no ads: every practice mode and ready-to-practice decks for all HSK levels 1-9 are free.
