It seems like there are lots of people who have a problem with talking loud as soon as they get on the phone. Myself included - usually. If I am in a long conversation this isn't the case.
I was thinking, why this might be the case, and this is my theory: You can't see the person you're talking too. Normally if you can't see the person you’re talking to, you will speak in a louder voice to be heard. Suppose you were in the woods, or on the other side of a wall or cubicle. So I think we speak up without thinking about it because it is what we have become accustomed to do.
What do you think? Do you talk loud on the phone?
