In all honesty, I don't think in Black Ops and Black Ops II the character actually spoke too much during levels aside from occasional dialogue that was nothing more than a response to someone. With a game like CoD you can sort of get away with non-talking protagonists since most of the time it's never too dialogue heavy in the levels themselves. Between CoD 1 until Modern Warfare 2, you never spoke in the level, and that didn't ruin the game at all. The only game to feature a silent protagonist and it failed in terms of lore was Ghosts, but aside from that, it's all worked fine in every other scenario. Sometimes a character doesn't need to respond in a level. And assuming you're more or less "just a soldier" this time around, most of the things you'll be hearing are nothing more than commands and action shout-outs, something you don't really need to respond to directly.
