Children talk with AI characters in real time through free conversation, everyday role-play scenarios, and narrated storybooks, while parents follow their progress in a web dashboard.
Technology
AI at the core of every lesson
01
Real-time voice conversation
Speech-to-speech dialogue over WebRTC on OpenAI's realtime models, with turn-taking and echo control tuned for young speakers.
02
Phoneme-level pronunciation feedback
Azure AI Speech scores every word and phoneme, so children get specific, encouraging feedback instead of a single grade.
03
Level-aware conversation design
Dialogue calibrated to CEFR levels from pre-A1 to B1, with distinct AI characters, role-play scenarios, and narrated storybooks.
04
Learning analytics for parents
Daily and weekly reports built from conversation and pronunciation data, delivered through a web dashboard.
