When aliens helpfully speak English (or any other Earth language), an issue comes up - what sort of accent do they have? As is the case for any language, "unaccented" English doesn't exist (although if argued, it could be in Oxfordshire, the origin of the modern English vernacular and the RP dialect) When you don't notice someone's accent, that's because they're speaking with a very familiar accent - either your own, or a "broadcast standard" like American Broadcast English in the US and Received Pronunciation in the UK. So what sort of accent would an alien, a being with a wholly unearthly language background, have?
