A Survey on Deepfake Generation and Detection using Deep Learning
Year: 2025
Type: article
Abstract: This fast-evolving artificial intelligence has opened the gates to new multimedia technologies with unprecedented abilities to alter the human voice and appearance. Voice cloning, which allows the synthesis of speech that is similar to a specific individual, presents exciting opportunities for creating personalized experiences across various domains-from virtual assistants to entertainment. Concurrently, the advancements in lip synchronization algorithms, such as the Wav2Lip model, have allowed for the smooth alignment of lip movements with spoken words, thus enhancing the realism of synthesized speech and improving accessibility for people with hearing impairments. However, these powerful technologies also present significant challenges. The potential for misuse of voice cloning, such as creating deceptive audio or impersonating individuals, raises serious ethical concerns. Furthermore, the increasing prominence of deepfakes - a kind of synthetic media where an individual can be depicted convincingly saying or doing things that he or she never actually did - poses a serious threat to information integrity and social and political implications can be grave. This paper reports the state-of-the-art in this regard, covering the methods, challenges, and issues surrounding each. We delve into the details of voice cloning techniques, discussing various approaches to audio feature extraction, speaker encoding, speech synthesis, and vocoding. Finally, we analyze the Wav2Lip model and other advanced methods for achieving accurate and realistic lip synchronization. Finally, we discuss the changing landscape of deepfake detection, discussing the strengths and weaknesses of current approaches, including those based on deep learning architectures such as convolutional neural networks and recurrent neural networks. This survey paper covers these cutting-edge technologies in an all-inclusive manner, pointing out their potential and limitations, and identifying key research directions for future advancements, including the development of more robust and ethical frameworks for their development and deployment.
