Chinese teacher pain · Essai solution
30-student class — teachers can’t give 1-on-1 Cantonese oral practice to each kid.
AI as personal practice partner. At partner schools, every student speaks with AI ~4 times a month.
Generic AI voice tools only handle Mandarin — Cantonese-native HK students have nowhere to practise.
Cantonese natively trained on HK usage, TSA / DSE prompts, colloquial + book-style vocabulary.
SEN and weaker students avoid speaking in class — end up practising the least.
Private AI dialogue with SEN pacing, repeat prompts, forgiving feedback. Weaker students +59% gain.
