Maybe It's Just Me, Over Precise Doesn't Always Work

Maybe it's just me, and it usually is, but when someone asks me more than once to repeat myself, the third time is worse than the first two. 

Let me illustrate. If somebody asks me the capital of Wisconsin. I'd say, "Madison, Wisconsin."

"What?"

"Madison, Wisconsin!"

They are not cupping their hand around their ear, so I assume that volume is not the issue. I may be speaking too fast. 

I'll slow it down to 33 and1/3 RPMs and be very precise. I twist your mouth all around to make sure every syllable is just right. "Ma di son, West con son."

The listener looks at me as if I'm trying to give directions to a tourist from Japan. 

The thing is, you usually say it right at 78 RPMs, but when you slow it down, you really have to deal with all the individual parts.
