An audio deepfake (also known as voice cloning or deepfake audio) is a product of artificial intelligence[1] used to create convincing speech sentences that sound like specific people saying things they did not say.[2][3][4] This technology was initially developed for various applications to improve human life. For example, it can be used to produce audiobooks,[5] and also to help people who have lost their voices (due to throat disease or other medical problems) to get them back.[6][7] Commercially, it has opened the door to several opportunities. This technology can also create more personalized digital assistants and natural-sounding text-to-speech as well as speech translation services.
