Intelligent AI Speaking Assignment Corrector

Before detailing the current setup, I’d like to highlight that I’m looking not only to improve the stability and automation of the existing system but also to explore better long-term solutions. In particular, I’m very interested in replacing the current AI service (Speak AI) with a custom-built recorder, as well as implementing an AI-powered avatar that could interact with students, ask them questions, record their answers, and provide feedback. My goal is to enhance the overall student experience and automate the evaluation process more intelligently and affordably. Please read description in word document attached.
