Thank you for saying it's one of your favourite concepts! That means a lot to me!
I'm afraid they are not from Age of Empires - they're Russian phrases downloaded from a language pronunciation website. However, the idea of them speaking when you select them or give them instructions is inspired by AoE so I can definitely see why you thought they could be the same sound effects!
As for your pronunciations, I'd actually say you were fairly accurate! :)
