If nothing changed from when they said that there will be full voiceover, we don't really know how the writing looks for our character. In many cases we have options like "tell about", which obviously will turn in full monologue from our character in voiceover.
I just used alt-f4 to get out of conversations to start them over cause my character's response did not turn out like I expected, at all.
Allow me to ease your pain for the future: Esc works as abort for cutscenes in SWTOR, so you can restart them without restarting the game.
