PinYintone

Mandarin tones are hard to hear — so Pinyintone lets you see them.

Speak a word and your voice becomes a live pitch curve, overlaid on a native speaker's. You immediately see whether your tone rose, fell, or stayed flat — and which syllable went wrong.

WHAT YOU GET • Live pitch (F0) curve as you speak • Per-character diagnosis with direction hints • Aspiration practice for p / t / k sounds • Practice any Chinese text you paste in • Works fully offline — no data charges • Interface in English, French, Arabic and Chinese

Built for learners whose first language has no tones. Just five minutes a day.

Your audio never leaves your device — only anonymous practice scores are used, to improve the app.
