Hearing voices in his head? Possibly.
I admit it's hard for me to go back to how I first "heard" them in my head these days, dating back to when I started watching Shudaki of Halved Studios' Let's Play of Marathon (though he has sadly privated his entire LP along with 70% of all his other ones too) where he used Microsoft Mike, Sam & Mary for the AI voices. So long I forgot what my originals mental voices for them sounded like.
It makes sense they'd have voice in the game universe though, as while it was only text on a screen for us and could easily be in the world too, Durandal did use his voice at least once to talk to Marcus in the manual's intro while he was on the Mirata. It's a bit hard to give out a faint chuckle in text only, plus it makes the world feel more alive. The only problem is that it makes the text harder to skim without cutting off their speech.
