You can easily find professionals that could do it for free in the internet, only to have this kind of work in their curriculum and not to mention using AI sound creation apps, anyway, they can use also voices that are already in the game as some droid voices from Iokath mobs or even rework some sound archives that are already in the game, easy and fast.
I'm sure this kind of simple solution could improve the players' experience and, of course, selling more of these kind of companions. The coolest it is, more popular it gets.
