About this app

Chinese pronunciation is not “hard.” It’s precise — and most language apps train it wrong.

TonePerfect is an AI-powered Mandarin speaking coach. You talk. The AI listens, scores every syllable, and tells you exactly what went wrong — the initial, the final, the tone, or the transition between them. No vague “try again.” No gamified noise. Real feedback on real speech.

▶ WHAT’S INSIDE

• AI Voice Call — have a real Mandarin conversation with an AI tutor. Pick a topic, speak naturally, and get a full post-call review with every mistake, every tone slip, and what to practice next. This is the closest thing to a private native tutor that fits in your pocket.

• Instant Pronunciation Analysis — record a syllable, word, or full sentence and get objective 0–100% scoring on tone accuracy AND pronunciation accuracy, with a syllable-by-syllable breakdown.

• Tone & Tone-Pair Mastery — Mandarin lives in the transitions. Dedicated drills for every tone pair (1-2, 2-3, 3-4, neutral combinations…), not just isolated tones.

• Targeted Initial & Final Correction — the AI isolates whether your b/p, zh/ch/sh, or -ang/-eng/-ong was off, and drills that specific sound until it clicks.

• Arcade Mode — Falling Tones, Tone Sprint, Tone Twins, Tone Rush, Tone Drill. Fast, competitive games that train your ear and mouth at the same time.

• Adaptive Placement Test — a quick assessment picks your real starting level so you don’t waste time on what you already know.

• Daily Sessions & Missions — short, focused daily routines with streaks, energy, and weekly goals. Duolingo rhythm, actual pronunciation content.

• Smart Spaced Repetition — the app learns your weak syllables, tones, and tone pairs, and forces you to face them until they’re solid.

• Interactive Pinyin Chart — every valid Mandarin syllable, tappable, in one screen. Drill any cell on demand.

• HSK 1–6 Content Packs — vocabulary and sentences aligned with the HSK levels you actually need.

• Native Reference Audio — compare your recording to a native speaker, A/B style.

• Progress You Can Measure — a full stats screen with tone accuracy over time, initial/final mastery, sentence-level trends, and leaderboard.

▶ WHO THIS APP IS FOR

• Learners stuck at “people understand me, but I sound wrong.”
• HSK 1 – HSK 6 students prepping for listening and speaking.
• Self-study learners who want an honest AI coach, not more flashcards.
• Heritage speakers polishing their accent.
• Anyone who’s ever been told “your tones are off” and given up guessing why.

▶ WHAT THIS APP IS NOT

❌ Not a vocabulary flashcard app.
❌ Not a grammar course.
❌ Not a toy.

TonePerfect is a dedicated speaking tool. You practice out loud. The AI tells you the truth.

▶ WHY IT WORKS

Most apps grade you on whether a pattern-matcher recognized your word. TonePerfect evaluates three independent channels on every syllable:

1. Initial (b, p, m, zh, ch, sh, r, j, q, x…)
2. Final (-an, -en, -ang, -eng, -ong, -ian, -üe…)
3. Tone (1st, 2nd, 3rd, 4th, neutral) — and the tone PAIR, because real Mandarin is transitions.

You see exactly where the error is. You fix that specific layer. You move on.
