Guys voice gets lower/sweeter/calmer when asking “how are you doing”… why lower?

He has a deep masculine voice but when asking he came closer, looked at me and asked in a nice, low, less deep way.

I was doing something so he was asking about the thing

Guys do not like to be quizzed. How are you doing means the quiz is a bout to begin for the guy. The inquisition has begun, therefore, we are being gently in our approach. We want you to know that we care... but we really don't care anyway. I am willing to listen to your drama for a little while until I can get what I came for...

That's from "Friends".
It's what Joey would say and how he'd say it when he saw an attractive woman.
