Deepfake Audio Detection using LLM
Project Goal
I am studying audio gereation using machine learning, i also do an online course of Audio processing, then i want to improve my skills. At that time i also do an assessment of Sony Audio Research intership and passed that so i think i should know audio processing and its related things, this is how i came up with this project idea.
Project Overview
With increase in tech; bad acitivities also increased on Internet so to reduce the risk of fake audio i developed an innovative deepfake Audio detection system using wav2vec 2.0 framework, achieving 94% accuracy in identifying AI-generated speech. The project addresses the growing challenge of audio deepfakes in security and authentication systems.
