Hey PH! I’m Nikolai, founder of TonePerfect. If you’ve practiced Mandarin pronunciation, you know the drill: You listen. You repeat. Maybe you see a pitch curve. But you don’t actually know what was wrong. Was it the tone? The initial? The final? Tone sandhi? Most tools stop at imitation. Very few give structural feedback. I built TonePerfect to fix that. It analyzes your pronunciation per character - breaking it down into tone, initial, and final - so you can see exactly what needs work. What you get: - Free 2-minute placement test → level + weak sounds - Adaptive spaced repetition → mistakes come back automatically - 4,000+ practice items (tones, initials, finals, sandhi, contrasts) - Custom text analysis - Works on iOS, Android, Web, Telegram Free tier: 10 detailed assessments/day Premium: unlimited I’d love sharp feedback: What’s missing from pronunciation tools today? What would make this indispensable? What would make you pay? Happy to answer anything - product, tech, or language side.
