What You'll See in Your Results
After you record, the AI gives you:
Overall Score
A number out of 100 telling you how close your pronunciation is to a native speaker. Color-coded: green is excellent, blue is good, amber needs work, red needs significant practice.
Per-Character Breakdown
Each Chinese character gets its own score tile. You can see at a glance which characters you nailed and which ones need work. If you said the wrong tone, a red dot appears next to that character.
Tone vs. Pronunciation Split
Your score is broken into two components:
- Tone accuracy — did your pitch pattern match the correct tone?
- Pronunciation clarity — were the consonant and vowel sounds correct?
This distinction matters because the fix is different for each. A tone problem means you need to adjust your pitch. A pronunciation problem means you need to adjust your mouth position or airflow.
Why We Built This
We built the free browser demo because we believe everyone should be able to check their Chinese pronunciation — not just people who can afford a tutor.
The reality is:
- Private Mandarin tutors cost $20-60/hour
- Most language exchange partners can't explain what you're doing wrong
- Generic voice assistants (Siri, Alexa) are designed to tolerate bad pronunciation, not correct it
- Recording yourself and listening back is subjective and unreliable
The browser demo gives you objective, AI-powered feedback in seconds, for free.
Limitations of the Free Demo
To keep the demo free for everyone, we limit it to 5 tries per day. This is enough to check a few phrases and get a feel for how the AI works.

Common Questions
Does it work on mobile browsers?
Yes. The demo works on any modern browser — Chrome, Safari, Firefox — on both desktop and mobile. You just need to allow microphone access when prompted.
Is my recording stored?
No. Your audio is processed for pronunciation analysis and then discarded. We don't store your recordings, sell your voice data, or use it for anything other than giving you feedback. See our privacy policy for details.
How accurate is the AI?
The AI uses the same speech analysis engine (SpeechSuper) that powers pronunciation assessment for language testing companies. It evaluates tone contour, consonant accuracy, and vowel quality against native Mandarin speaker data. It's not perfect on every edge case, but it's significantly more accurate (and more honest) than most human listeners.
Can I practice longer sentences?
The homepage demo is limited to short phrases. For full custom text practice (any sentence or paragraph), visit toneperfect.app/practice — also free, no account needed.
Why Not Just Use ChatGPT?
Large language models like ChatGPT can help with grammar, vocabulary, and even conversation practice. But they cannot evaluate your pronunciation — they can't hear you. They work with text, not audio.
TonePerfect works with actual audio recording and analysis. It measures the acoustic properties of your voice — pitch, formants, spectral features — and compares them mathematically against native speaker data. This is a fundamentally different capability from text-based AI.
What to Test First: Five Phrases That Reveal Your Level
Not all phrases are equally revealing. These five each probe a different classic weakness — test them in order and you will know exactly where you stand:
- 你好 (nǐ hǎo) — the third-tone sandhi trap: it should come out as ní hǎo, with the first syllable rising. Hear the reference on the nǐ hǎo page.
- 谢谢 (xiè xie) — a falling fourth tone followed by a light neutral tone; most beginners make the second syllable too heavy. Reference: xiè xie.
- 再见 (zài jiàn) — two fourth tones in a row. Each must fall sharply; learners tend to soften the second one. Reference: zài jiàn.
- 中国 (Zhōngguó) — first tone into second tone, the transition English speakers flatten most often. Reference: Zhōngguó.
- 对不起 (duì bu qǐ) — falling tone, neutral tone, then a proper low third tone at the end. Reference: duì bu qǐ.
Say all five in the free checker and note which syllables go red. That is your personal priority list.
How to Read Your Score Like a Teacher Would
The number matters less than the split behind it. Here is how to act on each pattern:
- Tone score low, pronunciation score fine. Your pitch is the problem: wrong contour, or right contour with too little range. Work through tone drills in our complete guide to learning Chinese tones — most tone problems respond to a week of focused contrast practice.
- Pronunciation score low, tone score fine. Your mouth position is off on specific initials or finals. Find the offending syllable on the interactive pinyin chart, read its articulation tip, and drill it against its confusable neighbours.
- Both low on one specific character. Usually a sign you learned that word from reading rather than listening. Listen to the native audio several times before re-attempting.
- Everything green. Move to harder material: longer sentences in the custom text tool, faster speed, new vocabulary.
Turn One Check Into a Weekly Routine
A single check tells you where you are; a routine changes where you are going. A loop that works for thousands of our learners:
- Monday: run the free test and write down your two weakest syllables or tones.
- Tuesday–Friday: ten minutes a day drilling exactly those weaknesses — syllable pages, tone pairs, then short sentences containing the problem sounds.
- Weekend: re-test with the same phrases and compare scores.
Week over week, the red tiles turn amber, then green. That visible progress is what keeps practice going — and it is why more than 20,000 learners have used TonePerfect to check and fix their Mandarin pronunciation.
Free Checker vs. Paid Options: What Do You Actually Need?
Honest answer: for finding out whether your pronunciation has problems, the free tools are enough — the homepage demo, the free test, and the custom text practice page all work without an account. You only need more if you want more volume and structure: unlimited assessments, spaced-repetition reviews of your weak syllables, placement tracking over months. That is what the paid tier adds. Start free, and upgrade only if the routine sticks.
Whichever tier you use, the workflow stays identical: record, read the per-syllable split, drill the weakest sound, re-test. The tool matters less than the loop — but a loop without objective measurement is just talking to yourself. That is the one thing a free browser checker genuinely changes: it turns "I think my tones are okay" into a number you can watch improve week after week. TonePerfect's apps hold a 4.6 rating largely because of this loop — learners can finally see their pronunciation moving.
