I think the actor comes out. Like when you are doing an impression you don't just change the tone and speech rate. But you add things like body gestures. You don't continue to use the same words, but change to fit where they are from and what they did in their life. This is applied to reading in another's voice as it slightly changes the thoughts in your brain to fit the person you are trying to be.
I think the phrase "fake it till you make it" applies here also, as it shows over time the profound effect this can have on your brain.
