Chinese AI Pronunciation Trainer — by TonePerfect.app Learn to speak Mandarin Chinese the right way. TonePerfect.app turns your browser into a personal pronunciation coach: select Chinese text on any page, right-click, and get detailed AI feedback on your pinyin, initials, finals, and tones. ▶ WHAT IT DOES A toolbar popup gives you a quick four-tone reference (mā · má · mǎ · mà) so you don't have to guess whether you just said "mother" or "horse." Type Hanzi or pinyin into the popup and jump straight into a recording session on toneperfect.app/practice with the text already filled in. Select Chinese text anywhere in your browser, right-click, and choose "Practice pronunciation on TonePerfect.app" to send it to the practice page. No retyping, no copy-pasting. The AI assessment gives you an overall score plus a syllable-by-syllable breakdown — so you can see exactly which initial, final, or tone needs more work, instead of just being told "try again." Your practice history is stored locally so you can come back and improve the same phrases. ▶ WHO IT'S FOR HSK learners at every level, beginners who can't yet hear the difference between mā and má, intermediate speakers fixing accent and tone habits, heritage speakers polishing their Mandarin, and tutors and teachers who want a quick recording tool for their students. ▶ WHY TONEPERFECT.app Most apps just say "try again." TonePerfect's AI tells you what actually went wrong: whether the initial or final was off, which tone you produced versus the one you intended, and whether you merged syllables or dropped a nasal ending. Every drill leaves you with measurable feedback. ▶ PART OF THE TONEPERFECT ECOSYSTEM Free companion to TonePerfect on web (https://toneperfect.app), iOS, and Android. Use the extension for quick sessions from any page; use the mobile apps for longer spaced-repetition practice and progress tracking. ▶ FEATURES AI-powered pronunciation assessment with tone analysis, per-syllable scoring for initial, final, and tone, audio playback of your recording, support for Hanzi and pinyin input, and a right-click context menu. Lightweight — no background polling and nothing injected into the pages you visit. ▶ PRIVACY The extension does not collect, store, or transmit personal data. It has no host permissions and does not read or modify webpage content. The only permission it requests is contextMenus, used solely to add the practice menu item when you select text. Selected text is sent to toneperfect.app only when you explicitly click the menu item or press Practice in the popup, and it's sent as a standard URL parameter — the same as if you had typed it yourself. Audio recording and AI assessment happen on toneperfect.app under its own privacy policy: https://toneperfect.app/privacy ▶ GET STARTED Install the extension and pin it to your toolbar. Click the icon to open the popup, or highlight Chinese text on any page and right-click to send it to the practice page. Read it aloud, get instant feedback, improve. 加油!
