I have to admit when I would be away on business trips and called home, and got the answering machine...well I knew our lab, would hear my voice and not understand where I was..so yes I talked to him and called him by name. My family claimed he loved it when they played back the answering machine to get messages and he heard my voice and then reheard me talking to him. He always would tilt his head from side to side when he heard my voice.
