Voice Cloning — record once, use everywhere

Record 20-30s of your voice, then any TTS in your lessons sounds like YOU.

How to clone

Teacher Admin → Voice Cloning → give it a name → click Start recording → read aloud for 20-30 seconds. Suggested script: “The quick brown fox jumps over the lazy dog. My students love English. Today is a good day to learn.”

Where your voice plays

  • 🎧 Async lesson playback (when student does homework alone)
  • 📯 Milestone certificate emails (“Congratulations Sofia!”)
  • ✨ AI Co-Teacher “speak this” button (teacher-triggered, never automatic)
  • 🎓 Live classroom PRE-CONFIGURED triggers (lesson PPT events you set up ahead of time)

Live classroom rules

In a live class, your cloned voice plays ONLY when YOU configured it to. Two paths: (1) lesson PPT events you set up ahead of time (e.g. "on correct answer → say Good Job"), and (2) the manual teacher reward button. There is NO random AI auto-fire during a live class because your real voice is already in the room.

Each TTS clip counts as 1 AI call. We recommend reserving the cloned voice for high-impact moments — not every micro-interaction.
