My family complains that I speak too loudly on the phone. I can't argue with that. But I can't help it sometimes (speak loudly, I mean. Not arguing). If the person on the other end of the line's voice is barely above a whisper, I feel like I have to talk loudly. I don't know why. And if the person is practically shouting, I TEND TO SPEAK LOUDLY TO MATCH THEIR TONE.
