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.

Try It Right Now

Stop reading and go test your pronunciation. Open toneperfect.app, click the mic button, and say 你好.

Your result might surprise you — in a good way, or in a "I need to practice more" way. Either way, you'll know where you stand. And that's the first step to getting better.

The best time to check your pronunciation is now. It takes 30 seconds and it's free.
