JustTalk AI
English speaking practice with AI
JustTalk AI offers English conversations with an AI partner, everyday role-play scenarios, and IELTS Speaking mock tests. It transcribes speech, flags grammar mistakes, and gives pronunciation feedback. Session history helps users track their progress.
I am a technical partner on the project. The stack includes Laravel, Python, and PostgreSQL. AssemblyAI handles speech recognition, while Sapling.ai and spaCy support grammar checks. Lesson data is sent over WebSocket.
