Fraud Call Detection

This application is designed to detect fraudulent calls by analyzing audio recordings. Upload an audio file to see if it is classified as a fraud call or a normal call. This project was developed as part of the GSLab Hackathon 2024, showcasing our innovative approach to fraud detection using speech recognition and machine learning techniques.
