This speaker I am working on right now is a mushmouth, and he is driving me bananas. He rolls over his words, and if you don't listen carefully, you miss what he is saying.
If you listen to the 10-second recording, this man spits out words like a machine gun. There is one portion where he spits out 7 words in less than one second. I couldn't believe it.
People like this are difficult to transcribe. When you encounter somebody like this, do you ask them to slow down or what?
