Like A Baby
Who could ever forget R2-D2? He is one of the many astromech droids on Queen Padmé Amidala’s Naboo Royal Starship during the invasion of Naboo. Aside from Queen Padmé, he also served Anakin and Luke Skywalker, where he showed great bravery in rescuing his masters and their friends. But did you know that his robotic sounds actually come from the sounds that a baby makes?
Although it does sound unlikely, the sound samples were heavily processed to achieve the pitch that will make it more robotic and electronic. According to the sound team, this is a common method that they use to create sound effects for several scenes of the film, as well as the sounds and languages of other species in the Star Wars universe.
