A new plan by Amazon to use artificial intelligence (AI) to dub films could spell the end for voiceover actors. The technology giant has patented a system that would see computers learn the voices of Hollywood stars such as Tom Cruise by studying their films. Amazon's computer systems could then automatically generate foreign language versions without any need for voiceover actors to dub the audio. The company used the example of "The Last Samurai" as an example use of the technology in its patent filing. By analysing how Cruise sounds in other films such as "Mission Impossible" and "Rain Man," Amazon could recreate his lines from "The Last Samurai" in French or Polish while still sounding recognisable.
