JYUTONE 
Plastic Cantonese
isn’t because you didn’t try hard enough.
What’s missing is millisecond correction, not another culture class. Jyutone traces the pitch of all nine tones. Speak 10–30 minutes a day and lock in the sounds and the tones.
Core · Correction
Say it right — not just say it.
Shadow a Cantonese line and AI scores every syllable: pronunciation, tone, completeness, and fluency, plus which character and which tone missed. Cantonese tones are hard to self-check. Here you see them syllable by syllable.
- Pitch traces for all nine tones
- Millisecond acoustic diagnosis
- Pinpoints the character and the tone
Nine tones · pitch reference
Core · Speaking practice
10–30 minutes a day builds muscle memory.
No history lecture, no cultural baggage. The loop is short: listen → shadow → record → review. A couple thousand everyday words, said and toned right, and the fear of opening your mouth drops.
- Short, frequent sessions that fit a workday
- A clear “today” practice you can stick with
- Culture comes from conversation — get the sound first

- Tone contrast at a glance
- Actionable next hints
- Offline preview + API-ready engine

Why Jyutone
Versus a traditional Cantonese course
What’s missing isn’t a textbook. It’s speaking feedback you can use immediately, and a practice rhythm that isn’t afraid of mistakes.
Traditional class / textbook
- History and culture first — the bar rises before you speak
- Standard written Cantonese, still “plastic” when you talk
- You finish a line and nobody names the wrong tone
- Fixed class times — one busy week and it breaks
Jyutone
- Straight to sound and tone — speaking is communication
- Tracks all nine tones; you train muscle memory
- Syllable-level correction; you know which tone missed
- 10–30 minutes a day, whenever you can
Start speaking. Get the tones right first.
