I'm not a fan of full PC voice at all but I don't think that matters since it's obviously incompatible with the origin system. You'd have to voice every line at the very least with every origin character and then probably twice more for a custom male and custom female character. Even voicing everything the PC says twice massively cuts down on the choice of options you get in conversation so 7+ is a non starter.
If we can get a few barks, reaction phrases and so on then sure I can see how that will help. But full voice surely isn't happening.
