I am an isfp and am a major motor mouth and a story teller. But I can also listen. I love to get other people to tell their stories. I will encourage them until I've gotten them into story telling mode.
Also, despite being an introvert, I really do not like to be alone unless I am outside walking. And, then, I might get bored and start talking to myself because I really need to verbalize.
As for silence in the room, no, I don't like that, either. I don't like lots of noise and competing conversations because I can't tune out the extraneous sounds... but a silent room for me is not silent. I hear the little noises that conversations covers up... the buzz of the electricity, etc. When I am by myself, I turn on music to listen to. I sing when I'm washing the dishes.
Hope that helps you to understand your dad a little better (if, indeed, he is a major motor mouth, too).
