ToneYin

Early access. New lessons and sound drills ship every few weeks. Tell us what to add next at hello@toneyin.ai.

ToneYin listens to you speak Mandarin and shows you exactly which tone slipped, syllable by syllable. Record a sentence, get a grade in seconds, and hear a native speaker say it back.

Most apps test whether you can read or tap the right answer. ToneYin tests the thing that actually makes Chinese hard to understand: your tones. Every recording is scored by a model trained on real learner speech, so the feedback reflects how a native listener would hear you, not just whether the pitch went up or down.

WHAT YOU GET

• Syllable-level tone feedback. See which syllables landed and which need work, with the pinyin and tone marks right there. • A guided path. Short lessons build from first hellos to confident everyday conversation, each one recycling the words you just learned. • Hear it. Every lesson line has native-speaker audio, so you can listen, then record, then compare. • Sound Library and Pronunciation Guide. Drill the sounds English speakers mix up most, with side-by-side pairs and clear mouth-position guidance. • Pick Your Own Topics. Type any situation, such as ordering coffee or a job interview, and ToneYin writes practice lines or a short dialogue for you to speak. • Free practice. Paste or type any Chinese sentence and grade yourself on it. • Bookmarks, daily goals, and streaks to keep you coming back.

WHO IT IS FOR

Beginners who want good habits from day one, intermediate learners whose tones still get corrected, and anyone preparing to speak Mandarin at work, with family, or on a trip.
