How real is this example

Timing and transcript are real. The scripted score only counts words, speed and filler words; real grading of grammar and vocabulary needs the AI key. Prep's Virtual Speaking Room is the Vietnamese model.

AI: the page first asks our small server function (/api/chat) which holds the AI key; the key is never in the page. No key is set yet, so every reply you see now comes from a script we wrote (badge: 'Bản kịch bản'). Once a key is added on Cloudflare the same page switches to real AI with no code change. Typing works everywhere; the 🎤 button needs Chrome or Edge outside the claude.ai frame.
