FakeYou is a Text-to-speech voice generator that offers a wide variety of character voices, in many languages, including celebrity and copyright character voices. From their terms of service: “This is a research technology for fun. You may not use FakeYou deepfakes for commercial use (unless otherwise stated, and only with specially denoted commercial voices).”
Obviously, it would not be wise to use the celebrity or other well-known character voices for videos or other commercial projects. I hoped some of the voices I didn’t recognize would be allowable for commercial use. However, in my testing, I was not able to find any voices that were specifically marked as commercial. Perhaps I wasn’t looking in the right place. But, with so many other text-to-speech options for content creators, it wasn’t worth it for me to keep digging to find voices I could use in my project (or figure out where such an indicator is on the voices I’m looking at.)
FakeYou provides tools beyond text-to-speech including, video style transfer, voice cloning, image generation, and a nifty looking tool called ‘Face Animator’ that lets you upload a photo and an audiofile and the tool will animate the face in the photo and lip-sync it to the supplied audio. However, the statement in their terms prohibiting commercial use except where explicitly noted, makes even the coolest looking technology uninteresting to me.
