Here's the real question: how do you pronounce 'Cubeo'?
Is the 'CU' pronounced like 'ice cube" or 'bear cub' or 'river current' or 'cumin spice'? Is the 'EO' pronounced like 'Oreo cookie' or 'Rodeo Drive'? Is the emphasis on the first syllable (CUBE-ee-oh) or second (cube-EE-oh)? That's like 16 possible combinations right there.
Inquiring minds want to know.
KEW-bee-oh. Or, to go full Achenarian accent, ka-YOO-bee-yo.
Given that David Braben himself pronounces Cobra as "Cob-Rah" I'd argue that you can pronounce the names in Elite Dangerous any way you want.
I've had disagreements with people who insist that Aisling is pronounced "Ash ling" saying that it's an old Irish name, even though she's a fictional character in a space sim game from another planet .... and there isn't a h in Aisling (I pronounce it as "A-ling", the A as in hay with "is" being silent because while silent letters is a part of word pronunciation, inserting letters that aren't in a word, isn't otherwise you could pronounce Aisling as Ais-Llanfairpwyllgwyngogerycheerwyndrobwyllantysilliogogoch-ling Duval)
I have a hard time sometimes watching Malic (he of Malic_VR) and the way he pronounces some of the system names in the game. But I accept that the way he pronounces names is just as valid as the way I pronounce them.
