Overview
A platform that helps students study more easily—especially chronically ill students and their teachers—by bringing lecture recordings, clear summaries, quizzes, and materials together in one place.
The Problem
Frequent or long absences lead to gaps in knowledge and limited practice. While the platform is designed primarily for chronically ill students, it is also useful for anyone who wants to study more efficiently. Many students rely on classmates' handwritten notes or have to gather missed materials in cumbersome ways, which adds stress and makes learning harder.
Our Solution
We built a platform that processes lecture audio (MP3). It uses speech-to-text for transcription, a large language model (Gemini 2.0 Flash) for analysis and summarization, and text-to-speech for accessibility. It automatically creates text summaries, generates quizzes and flashcards, and keeps all materials in one place. Students can also ask questions about the lecture in a simple chat.
Key Features
- Speech-to-Text: Transcribes lecture recordings (MP3) using advanced speech recognition (UWebASR ZCU)
- Summaries with AI: Clear summaries with key points and keywords (LLM Gemini 2.0 Flash)
- Text-to-Speech: Audio summaries for accessible listening (SpeechCloud ZCU)
- Interactive Quizzes: Automatically generated knowledge checks
- Flashcards: AI-generated cards for memorization
- Chat: Ask simple questions about the lecture content
- Material Organization: Materials organized by subject and topic in one place
- Cloud Storage: Secure storage on AWS S3 and DynamoDB
The platform works best with recordings made in a quieter environment where the teacher's voice is clear. Modern speech-to-text can handle a certain amount of background noise.
My Role
I coordinated a 10-person team and contributed to platform development.
