TonePerfect is the AI-powered Mandarin pronunciation coach that gives learners instant, syllable-level feedback on tones, initials, and finals.

TonePerfect is a Chinese pronunciation training app that uses on-device AI to score every tone, initial, and final you say. Learners record themselves reading Mandarin and receive an instant breakdown showing exactly which sounds and pitches need work — replacing vague "try again" feedback with measurable, syllable-level coaching.

TonePerfect is the first language app built end-to-end around Mandarin pronunciation. Founded in 2025, it combines a custom-trained tone model with phoneme-level pronunciation scoring to grade what learners actually say — not just whether the AI can recognize the sentence. The product spans Web, iOS, Android, and Telegram, with shared progress, spaced-repetition reviews, a 2-minute placement test, and a personalized daily workout. More than 10,000 learners worldwide — from HSK 1 beginners to heritage speakers polishing their accent — use TonePerfect to turn fuzzy pronunciation feedback into specific, measurable goals.
