Compare this performance by the real James Earl Jones from Rogue One… …with the A.I.-augmented Vader from Obi-Wan Kenobi… It doesn’t sound artificial; in fact, the work by Respeecher is remarkably seamless.
It certainly didn’t sound like a different actor was providing his voice; James Earl Jones’ signature bass came through loud and clear.
But it does sound like the young James Earl Jones, not the 91-year-old version.
You’d swear that’s the young James Earl Jones talking.
