[Star Wars] Why aren't the R2 (or the R4) units programmed to speak English, when they clearly understand it and are able to communicate in some form of language?

Because they're made cheap and replaceable. Specialized vocoders make that droid just that bit more expensive. Most of the time if they have to relay information back to organics, they are near mechanics who have learned to "understand" the Binary droid language, or they're hooked into a separate system with a built-in communication screen that translates for them.

[Also, it's not English. It's Galactic Basic.]
