Using AI to Replace Voice Actors

A recent story from Motherboard shows that the entertainment industry is also trying to automate voice acting. The outlet reports that voice over actors are being asked to sign away the rights to their own voices so that AI programs can be used to create “synthetic” versions of their voices. The outlet reports these new “contractual obligations are just one of the many concerns actors have about the rise of voice-generating artificial intelligence, which they say threaten to push entire segments of the industry out of work.”
Again, why? What is the point of doing this? The benefits of the technology seem minimal to me. Is it that a company can save money by generating huge swaths of bargain-bin voice acting? Let’s just leave that for robots to listen to.
