I'm unsure what you're getting at, but when people sing copyright songs or act copyright plays that do, in fact, get a license. So yes, if you train a human on someone's copyright content I do expect you to have a license to it.
I'm sure you've heard of covers? Well every cover that is published affords a royalty to (at least) the original authors of both the lyrics and composition. The artist may get some money, depending on how the work was licensed.
