TonePerfect is an AI pronunciation coach for 8 languages: Chinese (Mandarin), English, Spanish, French, German, Russian, Japanese and Korean. Working on your English accent? Record yourself and see a score for every sound.

Mandarin Chinese is the most complete course. 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." Real feedback on real speech.

▶ CHINESE (MANDARIN): WHAT'S INSIDE
- AI Voice Call — have a real Mandarin conversation with an AI Chinese tutor. Pick a topic, speak naturally, and get a full post-call review with every mistake, every tone slip, and what to practice next.
- 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 pinyin breakdown.
- Tone & Tone-Pair Mastery — Mandarin lives in the transitions. Dedicated tone practice 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 Chinese practice with streaks, energy, and weekly goals.
- 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 pinyin 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.
- Reference Audio — hear the target, then compare it with your own recording.
- Progress You Can Measure — tone accuracy over time, initial/final mastery and a weekly leaderboard.

▶ 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.

▶ BUILT FOR DAILY USE
