Is There a Law to Watermark Quote Unquote Audio and Audio and Watermark Text?

There's like a lot of uncanny valley stuff or multiple tech people I've seen who've been experimenting with it have said there's this one AI thing that makes it so your eyes are always looking at the camera no matter where your head is. So we're still in that uncanny valley part but then what's also interesting is how people are trying to figure out how do we watermark quote unquote audio and text in a way where people can tell that it's been AI generated for these purposes. It's a blessing and a curse when anyone can do this.
